Banner Engineering Multi-Beam® 2PBA 2-Wire Power Block, Photoelectric Sensor, 105 to 130 VAC

MULTI-BEAM 2-wire power block models 2PBA , 2PBB and 2PBD contain a low voltage power supply which utilizes a unique circuit to take a very small leakage current through the load and convert it to the dc power required to run the scanner block and logic module. They also contain the solid-state switch that operates the load, and a transient suppression circuit to prevent false operation from high voltage spikes on the incoming line. They are completely solid-state for unlimited operating life. MULTI-BEAM 2-wire power blocks offer the ultimate in simplicity of sensor hookup. They wire directly in series with an ac load, exactly like a limit switch. Response time of 2-wire power blocks is determined by the scanner block, which is 10 milliseconds on/off. A built-in false pulse protection circuit holds the output OFF for 100 milliseconds after power is initially applied to the power block.
