The Banner Engineering OPBA3 Power Block is an analog power block module for Banner’s OMNI-BEAM sensor family that combines power delivery with a dual analog output to drive and condition the sensor signal. It accepts 105–130 V ac at 50/60 Hz and provides two outputs: a non-inverting 0–10 V dc channel and an inverting 10–0 V dc channel, with a maximum combined load of 10 mA when both outputs are used. Available configurations include a 6‑ft, 5‑conductor PVC-covered cable version (OPBA3) and a Quick-Disconnect variant (OPBA3QD) that uses MBCC-512 cabling, tying into the sensor head power block while adhering to the 10 mA total load limit.
