Introduction Dynamic Ratings is a leading supplier of monitoring and control products to the electrical power industry. The B100 extends the company’s product range and provides a reliable and cost-effective electronic temperature monitor (ETM) and controller with numerous communications options.

Figure 1: B100

Hardware Features and Specifications

The B100 is a single unit housed in an aluminium enclosure, with a day and night readable LCD screen and four external user interface buttons.

The design life of the B100 is 20 years. It is expected to last much longer.

The electrical connections are made using screw terminal blocks, and the unit has multiple cable entry ports at the base of the enclosure. The internal operating system contains many functions to make sure the control system is in a healthy operating condition.

The permitted operating temperature range is -40°C to +70°C (-40°F to 158°F).

Enclosure Features

The B100 is supplied in a robust cast aluminium enclosure that is rated to IP66 ingress protection (NEMA 4 equivalent). Mounting is via four mounting holes (with supplied vibration mounts) on the sides of the housing. Cable entry is via multiple M20 (3/4 inch) and M25 (1 inch) ports in the bottom of the unit – spare ports are to be sealed to maintain the ingress protection. Additional enclosure features include a Gore® air vent for pressure and temperature compensation, and a padlock loop for locking of the enclosure.

I/O Type Electrical Data

The following I/O types are used in the B100, described here in detail.

Digital Input

The electrical characteristics of digital inputs are:

Absolute maximum voltage input range: ±390 V (276 VAC)

DC voltage range 15 – 390 VDC

AC voltage range 30 – 276 VAC

AC voltage frequency range: 47 to 63 Hz

Each digital input provides the following internal protection:

A self-resetting protection against over current conditions

Protection against over voltage transients and surges

Over voltage protection

Current limiting protection

Digital Output

Digital outputs are hardware relays that are configured in one of two ways:

1 x Form B (Fixed mapping for system alarm)

6 x Form C (User configurable outputs)

Digital outputs do not share any common pins and are electrically isolated. The digital outputs are electrically rated to the following:

Maximum AC carrying capacity: 10 A @ 250 VAC

Maximum DC carrying capacity: 10 A @ 30 VDC, 1 A @ 125 VDC resistive

Maximum making capacity: 30 A

Maximum AC breaking capacity: 3 A @ 120 VAC, 1.5 A @ 240 VAC

Maximum DC breaking capacity: 0.75 A @ 24 VDC, 0.4 A @ 125 VDC, 0.2 A @ 250 VDC

Each digital output provides internal protection against voltage spikes caused by inductive loads.

Analog Output – AO

Analog outputs do not share any pins and are electrically isolated. Analog outputs may be of either a current sink or voltage output type. Two DIP switches located on the board directly above the outputs are used to switch between volts and milliamps (mA). When the switch is in the up position, volts will be used. When the switch is in the down position, mA will be used. The electrical characteristics of each are:

Analog Current Output

Current range: 0 mA to 24 mA

Current resolution: 24 uA (0.1% of range)

Current accuracy: ±240 uA (±1% of range)

Maximum loop resistance 450 Ω

Analog Voltage Output

Voltage range: 0 V to 10 V

Voltage resolution: 10 mV (0.1% of range)

Voltage accuracy: ±100 mV (±1% of range)

Maximum output current: 5 mA

Each analog output provides protection against over voltage conditions.

Resistance Temperature Detector Input – RTD

An RTD input provides a three conductor connection that is intended to be used with a 3-wire, Pt100 (Platinum 100Ω) RTD. Each RTD input possesses an RTD+, RTD-, and common connection. The electrical characteristics are:

Temperature range: -50°C to +200°C

Temperature accuracy when using IEC 60751 Class A sensors: o ± 0.5°C between 0°C to 100°C o ± 1.0°C between -50°C to 0°C and 100°C to 200°C

Mounting

The B100 is suitable for external mounting on the transformer, but can be installed inside an equipment cubicle if required. If externally mounted, it is recommended that it is mounted in a height and location that is easily visible and accessible.

Mounting is achieved via four mounting holes (with supplied vibration mounts) on the sides of the housing. The metal ferrules have a hole diameter of 6.4mm (0.25 in.), suited to metric M6 or imperial 1/4-28 fasteners – 316 grade stainless steel is recommended.
