Description
The 2-channel IM1-22EX-R isolating switching amplifier is equipped with intrinsically safe input circuits.Sensors according to EN 60947-5-6 (NAMUR)or potential-free contact transmitters can be connected to the device.The output circuits feature 2 relays, each with 1 NO contact.
Via six switches on the front, you can set the operating behaviour for each channel separately and short-circuit monitoring (SC) on and off.
When using mechanical contacts, wire-break and short-circuit monitoring must be switchedoff or the contacts must be wired to resistors(II) (see circuit diagram).The Pwr LED lights green to indicate operational readiness. The 2-color LEDs 1 and 2 light yellow to indicate the switching status of the associated output. In the event of an input circuit error, the 2-color LED of the assigned faulty input turns red, with the input circuit monitoring switched on. Thereupon the output relay drops out.
