Micro Detectors URA/TA Amplifier Control Unit 24VDC (Timer + Alarm Output)
URA/TA 24VDC
The Micro Detectors URA/TA is the amplifier / control unit for the UR+DG family of remote photoelectric sensor heads. It drives a matched pair of miniature DG-series heads (such as the DGE/01-2C emitter and DGR/01-2C receiver), processing the optical signal and providing switched relay outputs, adjustable timing and an alarm output from a panel-mountable enclosure.
Running on 24 VDC, the URA/TA features a double timer with independent adjustments, sensitivity adjustment, and clear LED indication for supply, output state, alignment stability and alarm — making setup and fault-finding straightforward on long-range through-beam installations.
