EHPC210 Diagnostic Controller SIL 3
25 July 2018
Bifold has announced that the Partial Stroke Function of the EHPC210 Diagnostic Controller is now SIL3 Certified according to IEC 61508 : 2010 Parts 1-7 and meets requirements providing a level of integrity to: Systematic Integrity: SIL3 Capable.

The EHPC210 is a smart controller solution operating a single solenoid for partial stroke testing in pneumatic and hydraulic valve actuation. It is designed to meet the basic legislation requirements to perform a partial stroke test and to record the results.
The controller can interface with a valve switch box or has the added benefit of integral position feedback. The EHPC210 can be retrofitted onto existing systems to allow partial stroke testing to be performed.
The controller incorporates graphic display integrated rotary feedback measurement, low power modes, ESD monitoring and control. The enclosure assembly allows installation in zone 1 or zone 2 hazardous areas.
The controller features HART and Modbus communication as well as fully configurable control logic allowing hard wired interface to a local control panel or the clients control system.
Using the controller in association with Bifold zero bleed (in steady state position) solenoid technology can improve valve control, system power efficiency and reliability.
