The 2-channel IM1-22EX-R/24VDC 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 (work or quiescent current behavior, i.e.

NO/NC) as well as switch wire-break (WB)

and short-circuit monitoring (SC) on and off.

When using mechanical contacts, wire-break

and short-circuit monitoring must be switched

off 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 below light yellow to indicate the switching status of the corresponding 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 being switched on.

Thereupon the belonging output relay is deenergized.

■ Adjustable output mode (NO/NC)

■ Input circuits monitored for wire-break/

short-circuit (ON/OFF switchable)

■ Complete galvanic isolation
