Both sensors of the opposed mode pair are wired to model CI3RC2 us-
ing the two-wire hookup, which requires the use of two single channel
or one dual channel intrinsic safety barrier(s). In this mode, the SMI30
receiver sinks less than or equal to 10 milliamps in the "OFF" state and
greater than or equal to 20 milliamps in the "ON" state. The CI3RC2
senses this current change and switches internal relays that are easily
wired to most loads and/or additional control circuitry.
Model CI3RC2 is powered by either 105 to 130 or 210 to 250V ac. The
CI3RC2 supplies power to operate both the emitter and receiver.
Inputs are protected against short circuits. Built-in circuit diagnostics in-
dicate an overload of either input by pulsing an LED status light.
The CI3RC2 module has two isolated output switches. There is a 5
amp rated SPDT electromechanical relay, and a solid-state transistor
switch which may be used for logic-level interfaces.
For more information, refer to the datasheet packed with the CI3RC2.
