Long specification

Ex valve control modules, 35 mA ignition protection group IIC, 2 channel2-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.
