The 2-channel IMX12-DO01-2U-2UPR/24VDC solenoid driver provides an intrinsically safe output voltage limited in current

and voltage. Loads in the Ex area can thus

be supplied directly. Typical applications are

the control of Ex i pilot valves, the powering of

displays and transmitters. The device can be

powered from a power bridge that also transmits a collective fault signal.

The device is ready for operation when power is applied. The Pwr LED lights green to indicate operational readiness. A yellow LED indicates the switching state of the associated

output.

The device can detect a wire break or short

circuit when a high is present at the input.

The input then switches to high impedance

and the common alarm output becomes conducting. An error in the output circuit causes

the red LED to flash according to NE44.

The device can be used in safety circuits up

to SIL2 (high and low demand according to

IEC 61508) and meets the requirements of

the NE21. It is equipped with removable screw

terminals.
