    Intelligent control and diagnostic positioner ready to suit the most extreme environments This Intelligent Diagnostic Positioner (IDP) from Val Controls offers the best control, monitoring and diagnostic in a very compact enclosure of all type of valve systems. Since no programming is needed for our customers, this product is plug and play and with the graphical display and the 4 buttons it is very user-friendly. The flexible software included in the IDP, makes it very easy for our customers, to configure this unit exactly for their specific valve system. This product is very unique because of following advantages:

    - The units are already programmed - Very compact design - Cost saving for our customers - No extra cost for software, display etc. - Easy to install on existing valve systems

    The positioner fits following actuators on the market:

    - Hydraulic and pneumatic - Rotary and linear - Double acting and spring return

    It offers further advantages:

    - Control and diagnostic for hydraulic and pneumatic systems - Automatic intelligent calibration - Valve signatures with Val Controls Diagnostics Centre - Monitoring of auxiliary inputs and Dual solenoid configuration - Flexible and configurable with user- friendly menu - Local control panel - Multiple communication protocols - Ultra low power design - Installation on SIL systems without affecting the SIL level - Compact flameproof (Ex d) version in SS316 - All software for control and diagnostics included

    Standard Emergency Shutdown System vs. Val Controls Intelligent Diagnostic Positioner A standard ESD system is usually only tested during shutdown or when an emergency occurs. The problem is that the system cannot be tested when the factory is running. Since it can disturb the process and can give problems reaching the maximum production capacity. A standard ESD system can be designed as shown in the picture below. The controller sends a signal to the IO module that will de-energize the solenoid valve and the valve will close.

    The IDP from Val Controls can be used on already installed systems with few modifications. It is easy to add the ability for extra testing, security and diagnostic. The picture below shows how the IDP can be added to an existing system or used on a new installation.

    Models The Val Controls Intelligent Diagnostic Positioner is available in two different hardware versions. We can offer these units in a flameproof version or in a version for DIN rail mounting. Both versions have the same flexible software.

    IDP24-AF: The Val Controls Intelligent Diagnostic Positioner Flameproof This model is designed in a SS316 flameproof enclosure approved for hazardous areas. With this compact design it is cost saving, it can be fitted on existing or on new systems. If needed we can offer this version with a customized local control panel.

    - Dimensions: LxWxH 155 x 140 x130mm - Weight: 5kg - Gland entries: 6 x M20x1.5 - Ingress protection IP68/66 - Flameproof version, ex d - SS316 enclosure - ATEX and IECEx approved - Compliance to EN 60079-0 and EN 60079-1

    IDP24-A: The Val Controls Intelligent Diagnostic Positioner Advanced The DIN rail housing is intended for already installed systems or customers who have their own housing and installation.

    - Dimensions: LxWxH 157x86x57mm - 35mm DIN rail mounting according to EN50022 - Easy mounting of wires

    The Val Controls Intelligent Diagnostic Positioner This advanced IDP offers a large range of connection possibilities. By connecting a battery or separate power supply, the IDP can record a full stroke profile in case of an ESD for later analyzing. Features: - Valve testing and operation - Automatic intelligent calibration - Intelligent diagnostic - User-friendly menu - 4-20mA position transmitter - 4-20mA pressure transmitter - Val Controls Diagnostic Centre for configuration of IDP and analysis of valve

    signature on PC - Store configuration and analysis data on a memory card (micro SD) - Local control panel with button to initiate a test - Multiple communication protocols - Multiple solenoid valves, i.e. one for ESD and one for diagnostic - Automatic detection of ESD signal - Battery backup or separate 24VDC to provide full stroke signature in case of ESD - Temperature sensor - Any 4-20mA sensor - Pump unit controller

    Configurations The IPD can be configured to use the ESD solenoid valve for the partial stroke testing. It can also be configured for a separate solenoid valve. The configuration with only one solenoid valve makes the IDP easy to install on existing systems. It does not require extra wiring to the control room. By adding an external power supply the IDP can record the full stroke signature during an ESD. This signature can then later be retrieved. The electrical circuit in the IDP which is connected to the ESD will not affect the SIL level The IDP can also be connected to a separate solenoid valve. This makes the IDP ideal for control and diagnostic for a large range of setups.

    SIL

    The IVC is designed to be used in safety instrument systems for partial stroke testing of emergency shut-down valves with no negative impact on the safety function. The IVC does not adversely affect the execution of the safety function. There exist two types of SIL circuits, which both are optional.

    IVC with SIL expansion card This solution makes it easy to retrofit the IVC as no extra wiring is required. The unit is powered through the ESD line, which means that the IVC will lose power during an ESD.

    IVC with SIL expansion card + extra 24 VDC When using an external power supply then the IVC can measure performance data in case of an ESD. This is beneficial as data from ESDs can be used to verify the status of the valve system.
