The Banner MAXI-AMP model CI3RC2 (p/n 36606) is a selfcontained module which converts the current output signal of an SMI Series intrinsically safe sensor to a trip point switch. 

Banner SMI Series intrinsically safe sensors carry Factory Mutual Research's rating for use in hazardous areas.  Sensors are wired to model CI3RC2 using the two-wire hookup through an intrinsically safe barrier. Refer to the hookups, page 2. The SMI Series sensor sinks ≤ 10 milliamps in the "OFF" state and ≥ 20 milliamps in the "ON" state.  The CI3RC2 module senses this current change and switches internal relays that may be easily wired to most loads and/or additional control circuitry. 

Model CI3RC2 is powered by either 105-130 or 210-250V ac.  It supplies dc power to operate a single sensor or both the emitter and receiver of one SMI Series opposed mode sensor pair. The sensor's input to the CI3RC2 is protected against short circuits. 

Built-in circuit diagnostics indicate an input overload by flashing an LED status light. 

The MAXI-AMP 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 logiclevel interfaces. 

Banner also offers the CI3RC2 Current Trip Point Module as part of a kit.  See page 2 for further information.  The CI3RC2 may be used with the following Banner Intrinsically Safe sensors: SMI30 Series, SMI912 Series.

**WARNING** This photoelectric sensing product does NOT ! include the self-checking redundant circuitry necessary to allow its use in personnel safety applications.  A failure or malfunction can result in _either_ an energized or a de-energized output condition. 

Never use this product as a sensing device for personnel protection.  Its use as a safety device may create an unsafe condition which could lead to serious injury or death. 

Only MACHINE-GUARD and PERIMETER-GUARD Systems, and other systems so designated, are designed to meet OSHA and ANSI machine safety standards for point-of-operation guarding devices.  No other Banner sensors or controls are designed to meet these standards, and they must NOT be used as sensing devices for personnel protection. 

_SMI Series sensors are certified intrinsically safe ONLY when used with certified energy-limiting intrinsically-safe barriers._ Banner does not itself manufacture intrinsically-safe barriers.  Barriers may, however, be purchased from Banner.  Kit CI2BK-1 includes one each of the following: single channel barrier, CI3RC2 amplifier, RS-11 socket, DIN rail mount, and a 70 mm DIN rail for mounting the socket. Kit CI2BK-2 provides a dual channel barrier in place of the single channel barrier. Barriers are available separately (below right). 

An SMI Series sensor  is wired through a barrier using the 2-wire hookup. In the 2-wire hookup configuration, the sensor acts as a current sink, drawing less than 10mA in the OFF state and more than 20mA in the ON state.  Model CI3RC2 senses this current change and switches internal relays.  The SPDT electromechanical relay in the CI3RC2 can switch a 

load which draws up to 5 amps (see specifications).  The SPST solid-state relay can switch a dc load of up to 30V dc, max.; 20mA, max. 

SMI Series emitter-only units also use the 2-wire hookup through a barrier (see hookup diagram "B").   Emitter power (24V dc, 25 mA maximum) is obtained at pin #3.   This is sufficient to power _one_ emitter. 

The user of this equipment is responsible for the proper installation and maintenance of the equipment, and must conform with certification requirements relating to barriers and to maximum allowable capacitance and inductance of field wiring. If you have questions about these requirements, Banner applications engineers can refer you to the proper authority.
