The relay control module type PMS consists of three separate devices. Each of the modules can operate independently or they can be interconnected with each other.

The actuating relay module PMS-0/*/* can be powered from a non-intrinsically safe or an intrinsically power supply.

Measuring module: PMS-1/*/*, PMS-2/*/*, PMS-3/*/*, PMS-9/*/*, have two intrinsically safe measurement channels, and PMS-5/*/*, PMS-6/*/*, PMS-7/*/*, PMS-8/*/*, have four channels. These modules differ in the permissible measurement line resistance.

Intrinsically safe measuring inputs with the protection rating of ia are controlled by a rectifier diode e.g. 1N4007. Each (measurement) input circuit is controlled by a short circuit, a break and a current flow direction.

Depending on the user’s needs, the relay control module can be used for galvanic separation of intrinsically safe and/or non-intrinsically safe circuits.

The dual-channel measuring module of the relay control module has a SIL-3 safety integrity level.

The actuating module of the relay control module has a SIL-2 or SIL-3 safety integrity level. The 4-channel measuring module has a SIL-1 integrity level.

The relay control module is designed in accordance with the good engineering practice with respect to their safety and meet the requirements of the standards PN-EN 60079-0; PN-EN 60079-11; IEC 61508; PN-EN ISO 13849-1; PN-EN 62061.
