900MB SeriesModbus-RTU I/O ModulesThe 900MB series is a high-performance line ofmulti-function I/O modules. These units featureuniversal input/output ranges and an intelligentmicrocontroller to provide extreme flexibility andpowerful monitoring and control capabilities.Select from a variety of analog and discrete I/Omodels to meet your application requirements.
To ensure unsurpassed performance, these I/Omodules employ the latest digital technology.State-of-the-art flash microcontrollers plus opti-cally isolated input, output, power, and networkcircuits increase noise/transient immunity andprevent ground loops. Status LEDs provide diagnostic feedback and visually indicate whichchannels are outside their calibrated range.
Sophisticated watchdog timer functions allowthe application to define the module's failsafeoutput state. The watchdog timer invokes thefailsafe condition when communication betweenthe host and module exceed a duration specifiedby the application. For further security, a secondhardware watchdog timer monitors the micro-controller for failed operations or a “lock-up”condition and automatically resets the unit.

n DescriptionThis signal conditioner is a four-channel analoginput module with four discrete outputs. It provides isolation between input, output, power,and network circuits. Network communicationadheres to the industry-standard RS-485 ModbusRTU protocol. AC and DC power sources aresupported with nonpolarized, diode-coupled terminals.
The inputs accommodate wide DC voltage orcurrent ranges. Flexible discrete outputs operateas alarms or on/off controllers. As limit alarms,each discrete output can be configured with highand/or low setpoints exclusively tied to an analoginput channel. Alarm trips function without hostcommunication enabling low-cost stand-alonealarms, as well as local backup for the primarycontrol system. Otherwise, on/off control isbased on commands issued by the host system.
Combining flexible transmitter functions, mixedsignal I/O, alarm support, and a network inter-face in a single package, makes this instrumentextremely powerful. Multi-channel design addscost-efficiency and allows high-density mounting.Plus, safe, rugged construction makes thesemodules reliable for use in both control roomand distributed field I/O applications. Custommodule configurations are also possible (consultfactory for details).

n DescriptionThis signal conditioner is a dual or quad-channelanalog input module with one discrete/relay out-put per input channel and a Modbus interface. Itfilters and linearizes RTD or resistance inputswhile providing isolation between input, output,power, and network circuits. Lead wire compen-sation and upscale/downscale sensor breakdetection are standard. Low voltage AC and DCpower sources are supported with nonpolarized,diode-coupled terminals.
The programmable inputs accommodate fourRTD types plus wide-range resistance signals.Flexible discrete outputs operate as alarms oron/off controllers. As limit alarms, each discreteoutput can be configured with high and/or lowsetpoints exclusively tied to an analog inputchannel. Alarm trips function without host com-munication enabling low-cost stand-alone alarmsas well as local backup for the primary controlsystem. Otherwise, on/off control is based oncommands issued by the host system.
Combining flexible transmitter functions, mixedsignal I/O, alarm support, and a network inter-face in a single package, makes this instrumentextremely powerful. Multi-channel design addscost-efficiency and allows high-density mounting.Plus, safe, rugged construction makes thesemodules reliable for use in both control roomand distributed field I/O applications. Custommodule configurations are also possible (consultfactory for details).

n DescriptionThis signal conditioner is a two-channel analoginput module with discrete outputs and Modbuscommunication. It conditions periodic or pulsewaveform inputs and provides solid-state relaysfor limit alarms or ON/OFF control.
Versatile inputs accommodate many applicationsusing TTL, magnetic pickups, proximity sensors,or a variety of switches (high/low-side transistor,dry contact, open drain, open collector). Bipolarand unipolar waveforms are supported with aselectable input bias that accepts both zero andnon-zero crossing signals. Voltage threshold andrelative hysteresis are also user selectable.
Inputs may also function as event counters withseparate microcontrollers for each channel. Themodule counts pulses on the positive or negativeedge. It can wrap around to zero for continuouscounting, latch at a programmed count value(setpoint), or automatically reset itself to zeroafter reaching a setpoint value. Software controlsenable remote resets. A variety of filters helpremove noise, jitter, and other mechanical effectsto prevent false counts.
The discrete outputs can operate as independentalarms or provide on/off control regulated by thehost system. As limit alarms, each output can beset for high and/or low setpoints exclusively tiedto an analog input. These low cost modules areideal for standalone alarms as well as for localbackup of the primary control system.

Acromag’s RS-485 network repeater device allows users to take full advantage of the RS-485 standard’s extended communication distances and multi-dropping capabilities. In addition, these devices offer field selectable End-of-Line Network (EOLN) terminations on both the A and B networks.
Operation is transparent to all devices and no handshaking is required. Up to thirty-two RS-485 devices can be driven. Network repeaters are ready to mount on any base plate. Or, for a harsh environment, it can be installed in a NEMA enclosure of your choice. No enclosure is necessary for use in a laboratory or office. Installation requires mounting, connecting power and cables, and setting the baud rate.
ApprovalsUL/cUL listed: Energy management equipment
Key Features & Benefits■ Designed for use with Johnson Controls
N2 or BACnet bus
■ No handshaking
■ No extra control lines
■ I/O signal isolation
■ Baud rates of 600, 1200, 2400, 4800, 9600, 19.2K, 38.4K, and 76.8K are switch selectable
■ Field-selectable end-of-line network terminations on both A and B sides
■ Electrical transient protection is provided. This protects the host computer from destructive noise spikes and other transient signals.
■ Status LED’s indicate transmission direction and power applied.
■ 24/115/230V AC power available
■ No separate transformer required with 24V AC units (4683-TTM-3F)
OperationModel 4683-TTM-xF network repeaters isolate and boost RS-485 signals allowing communication signals to travel another 4000 ft. Each repeater permits the addition of another 32 unit load to a network.
The repeater has two RS-485 “sides” known as the A and B sides. The A side typically connects to the network towards the host and the B side connects to the extended network. Functionally, the A and B sides are equivalent.
Repeaters receive AC power through a 3-screw terminal strip. Transient signal protection is provided on both RS-485 sides.
When both RS-485 lines are idle, each side is in receive mode. When a ‘1’ to ‘0’ transition is detected (signifying a start bit) on either side, the opposite side’s transmitter is enabled. The transmitter stays enabled for one character’s time (based on the baud rate switch setting). The received character is then passed through.
For N2 or BACnet MS/TP bus ◆ Drives up to 32 RS-485 devices ◆ Isolates and boosts signal up to 4000 ft.

■ Communication SpecificationsBaud RatesSwitch settings on unit for 600, 1200, 2400, 4800, 9600, 19.2K, 38.4K, and 76.8K baud rates. Switch must be in the proper baud rate position for proper operation.RS-485 Bus LoadingOne unit load equivalent.RS-485 Bus DriveComplete RS-485 compliance for up to 32 unit loads (31 unit loads if a repeater is used).End-of-Line Termination NetworkThe EOLN termination network is shown on the right and is individually selected on both the A and B sides by a pair of shorting clips. The A-side is controlled by jumper pair J1, J2 and the B-side is controlled by jumper pair J3 and J4.The EOLN termination network is enabled for the A side or B side when the associated pair of jumpers are positioned over pins 1 and 2. Conversely, the EOLN is disabled (out of the circuit) when the pair jumpers are positioned over pins 2 and 3.DuplexHalf duplex only.Data FormatTen bits typical (1 start bit, 8 data bits, and 1 stop bit). Other formats are supported.
