Description
The Allen-Bradley 1771-OBD module is a DC output module that has 16 outputs. It is located on Allen-Bradley 1771-A1B and 1771-A4B I/O chassis, and its user supply voltage can range from 10 to 60 Volts of DC power. With a current rating of 2 Amps per output of resistive current and of 0.2 Amps per output pilot duty current, the nominal on-state output voltage of the 1771-OBD module is 48 Volts DC. It has a maximum surge current of 4 Amps per output for 10 milliseconds, which is repeatable every 2 seconds. The 1771-OBD module has a minimal load current of 2.5 mA, and its maximum on-state voltage drop is 1.5 Volts DC while its maximum off-state leakage current is 0.5 mA.
