115VAC Infrared Photoelectric Amplifier with Time Delay 

This 115vac amplifier operates with modulated infrared lights that provide high immunity to ambient light. It has an electronic circuit that is designed to detect only those signals with the correct frequency and phase relation. This however, excludes interference from other barriers.  This amplifier manual features relay output, test input, 4 different selectable transmit frequencies and detection range up to 70m. 

Includes:

• Transistor output npn/pnp
• Relay output
• Adjustable switch-ON and switch-OFF delay 
• System power 20%/ 100% switchable
