Isolating switching amplifier2-channelIM1-22EX-R/24VDC

The 2-channel isolating switching amplifierIM1-22EX-R/24VDC is equipped with intrinsi-cally safe input circuits.

Sensors according to EN 60947-5-6 (NA-MUR) can be connected to the device or po-tential-free contactors.

The output circuits feature 2 relays, each withone NO contact.

Six front panel switches are available to setthe output mode separately for each channel(NO/NC mode), as well as to enable/disablewire-break (WB) and short-circuit (SC) moni-toring separately.

When using mechanical contacts, wire-breakand short-circuit monitoring must be switchedoff or the contact must be wired with resistors(II) (see circuit diagram).

The Pwr LED lights green to indicate oper-ational readiness. The 2-color LEDs 1 and2 below light yellow to indicate the switch-ing status of the corresponding output. In theevent of an input circuit error, the associated2-color LED turns red, provided the input cir-cuit monitoring function is activated. There-upon the corresponding output relay dropsout.

■ ATEX, FM

■ Installation in zone 2

■ Adjustable output mode (NO/NC)

■ Input circuits monitored for wire-break/short-circuit (ON/OFF switchable)

Isolating switching amplifier2-channelIM1-22EX-R/K51

The 2-channel isolating switching amplifierIM1-22EX-R/K51 is equipped with intrinsicallysafe input circuits.

Sensors according to EN 60947-5-6 (NAMUR)or potential-free contact transmitters can beconnected to the device.


You can set each channel separately to work/closed current, i.e. NO/NC mode and multiplysignals via 3 switches at the front. The switch-ing state of channel 1 is thereby transmitted tothe outputs 1 and 2. You can also set the out-put mode separately for each channel.

The Pwr LED lights green to indicate oper-ational readiness. The 2-color LEDs 1 and2 below light yellow to indicate the outputswitching status. In the event of an input cir-cuit error, the associated 2-color LED turnsred, provided the input circuit monitoring func-tion is activated. Thereupon the correspon-dent output relay drops out.
