4 Product Description
In the following chapter the individual variants are described.
All information provided in this chapter is not part of safety function.
The devices are intended exclusively for industrial use. The relay couplers of the IM12-CD…
series ensure safe galvanic isolation between contact and control circuits. Possible applications
are e.g. remote reset, fire alarm test or the remote calibration of strain gauges.
The devices can also be used for safety-related applications up to and including SIL3 (high and
low demand according to IEC 61508) (hardware fault tolerance HFT = 1).
IMX12-CD01-2R-2U The IMX12-CD… relay couplers are equipped with three relay outputs (change-
over switches). Depending on the input level, the input signals are interpreted
as low or high level and provided as a corresponding output signal. The inputs
are not polarized. Input E1 and input E2 switch output A1 or output A2 With
input E3, output A1, output A2 and output A3 are controlled simultaneously. The
device is powered by the input signal (Loop Powered)
