Product Description
The Allen-Bradley 1794-OB32P is a FLEX I/O 24V DC digital output module with 32 electronically fused outputs, divided into two isolated groups of 16. Each output is protected against temperature overloads and shocks, with yellow status indicators for each channel. It measures 1.8 x 3.7 x 2.1 inches, mounts on a DIN rail, and is compatible with 1794-TB32 and 1794-TB32S terminal bases. Key specifications include an on-state voltage of 10-31.2V DC (with a 0.5V DC drop), a per-channel output current of 1-500 mA (14A total), a surge current of 2A for 50ms (repeatable every 2s), and a leakage current of 0.5 mA. The module draws 103-273 mA at 10-31.2V DC, has a 0.5ms OFF-to-ON delay and a 1ms ON-to-OFF delay, and provides 50V continuous isolation. It dissipates a maximum of 18.1 BTU/hr (5.3W) at 31.2V DC. Channels 0-15 can deliver a total of 6A, while channels 16-31 can deliver a total of 8A. It's a sourcing discrete output module ideal for controlling 24V DC devices like indicators, sounders, and electrical loads in PLC applications.
Is Your Device Showing These Signs?
The Allen Bradley 1794-OB32P FLEX I/O output module commonly experiences failures due to blown output fuses, often caused by inductive load spikes or wiring shorts. Technicians frequently address issues stemming from backplane communication errors, requiring inspection and reseating of the module within the chassis, or replacement of the FLEX I/O adapter. Field wiring terminations at the terminal block are a source of problems, so ensure proper torque and wire gauge to prevent intermittent connections and module malfunction. Overvoltage conditions and exceeding the module's current rating lead to component degradation, necessitating repair or replacement of the output module.
