MAXI-AMP^™ CI3RC2 Module
Banner MAXI-AMP module model CI3RC2 (part number 36606)
is a self-contained module which converts the current output signal
of an SMI30 Series sensor to a trip point switch.
Both sensors of the opposed mode pair are wired to model CI3RC2
using 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 ≤10 milliamps in the "OFF" state and ≥20
milliamps in the "ON" state. The CI3RC2 senses this current change
and switches internal relays which are easily wired to most loads and/
or additional control circuitry.
Model CI3RC2 is powered by either 105-130 or 210-250V ac. The
CI3RC2 supplies power to operate both the emitter and receiver.
Inputs are protected against short circuits. Built-in circuit diagnos-
tics indicate 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.
