Banner Engineering's OPBA2QDA3 Power Block Module is a power block for OMNI-BEAM modular photoelectric sensors, providing the regulated low-voltage DC power required to run the sensor head and, when used, its logic module. The OPBA2QDA3 variant, described as “Omni Wiring Changed” (model 31782), accepts 105–130 VAC input at 50/60 Hz and supports up to 500 mA of output current at 130 VAC, with a maximum 200 mA alarm output. Weighing about 0.39 lb, this unit is designed to pair with OMNI-BEAM scanner blocks and logic modules to interface the sensor with external circuitry and loads.
