Isolating switching amplifier
2-channel
IM1-22EX-T
The dual-channel isolating switching amplifier
IM1-22EX-T is equipped with an intrinsically
safe input circuit.
Sensors according to EN 60947-5-6 (NA-
MUR) can be connected to the device or po-
tential-free contactors.
The output circuits feature two potential-free
and short-circuit protected transistors.
Six front panel switches are available to set
the output mode separately for each channel
(NO/NC mode), as well as to enable/disable
wire-break (WB) and short-circuit (SC) moni-
toring separately.
When using mechanical contacts, wire-break
and short-circuit monitoring must be switched
off or the contact must be wired with resistors
(II) (see circuit diagram).
The green LED indicates operational readi-
ness. The switching status of the correspond-
ing output is indicated yellow by the two col-
or LED. In the event of input circuit errors the
dual color LED changes to red, provided the
input circuit monitoring function is activated.
Thereupon the related output transistor is de-
energized.
