PULSE AND POWER CYCLE
NOTE: Remove power when changing Configuration settings
(2)
Pulsed configurations require current limiting in the operator. The IRB-RET will pulse the
power lines when no obstruction is present.
(3)
Four-wire output provides an emitter and collector connection to the operator. The emitter is
generally connected to the circuit common (ground) and the collector is typically an open-
collector output using a pull-up resistor to low-voltage DC power.
