DETAILED DESCRIPTION

S142 A….

μ-Processor controlled amplifier for one set of photoelectric sensors (type MOFT/R), plug in 11-pin base. The S142 A RN…. have relay and NPN / PNP transistor output, diagnostics for sensors, test during operation, alignment help via LED or alternation of alarm output, level indication for dirt accumulation, manual or automatic emitter power regulation and two emitter codes for high neighbor immunity.
LED indication: Automatic gain, output, level, emitter or receiver fault. Diagnostic: If a fault occurs on either the emitter or receiver the Alarm LED and output will turn ON.
Emitter fault: If the wires are short-circuited the “Code A, Yellow LED” flashes at a rate of 2 Hz. If the wires are broken the “Code A, Yellow LED” flashes at a rate of 4 Hz.
Receiver fault: If the wires are short-circuited the “Code B, Green LED” flashes at a rate of 2 Hz.If the wires are broken the “Code B, Green LED” flashes at a rate of 4 Hz.

Note1: Replacement for S1420156xxx : S142ARNT924, S142ARNT024, S142ARNT115, S142ARNT230
Note2: By selecting sensors for explosive environments can cover the ATEX requirements
