The S142CRXM115 is a microprocessor-controlled amplifier relay designed for photoelectric sensor systems, specifically rated for 115 VAC operation (98 to 132 VAC, 45 to 65 Hz). It features an 8 A/250 VAC SPDT relay output with manual emitter power regulation, self-diagnostic functions, and alignment help via LED indication. The amplifier supports a multiplexed master/slave system with a 20 ms cycle time, allowing up to 11 photoelectric switches to operate in close proximity without optical crosstalk. Key technical specifications include a receiver supply voltage of 5 VDC, emitter supply of 15 V square wave, response times of 20 ms per system, and operating temperature range of -20°C to +50°C. This amplifier is ideal for industrial automation applications requiring reliable sensor signal processing with built-in diagnostics and neighbor immunity features.
