Long specification

Ex valve control modules, 35 mA ignition protection group IIC, 2 channel
2-channel valve control modules in 22.5 mm width with external power supply,
to control valves in Ex zones 0,1,2 from the safe zone.

The module comes with full four-way, 2.6 kV separation.
On the input side, NPN/PNP switching sensors can be connected.
On the output side, there are optionally three 35 mA driver steps per channel for ignition protection group IIC with
a minimum driver voltage of 12.5 V/13.5 V or 14.5 V available.
 An additional alarm contact ("a" contact) reports status and error messages
The module can be configured using standard FDT/DTM software.
