A-B 1771-OJ

1771-OJ is a pulse output expansion module under the Allen Bradley PLC-5 series, designed specifically for motion control scenarios that require high-frequency pulses and multiple independent channels. In the 1771 I/O system, this module is positioned as a critical pulse interface between the processor and the stepper/servo driver, responsible for the core task of accurately converting the internal calculation results of the PLC into high-speed pulse sequences and allocating them to multi axis actuators
