General Description:
The D1045 is a dual channel, actuated in alternative, DIN Rail Digital Output module enabling a Safe Area contact, logic level or drive signal, to control a device
in Hazardous Area, providing 3 port isolation (input/output/supply). Typical applications include driving 1 or 2 positions directional solenoid valves or other process control devices.
It can also be used as a controllable supply to power measuring or process control equipments in Hazardous Area.
Output channels have the capability of driving loads both in Gas Groups IIC and IIB/IIA with different safety parameters.
Function:
