EtherNet/IP and PLC-5 I/O Signal Processing Characteristics
The 1771-OFE3 operates within the Allen-Bradley PLC-5 1771 I/O architecture and exchanges output data through the chassis backplane interface. The module supports four individually isolated differential analog outputs, allowing separate current loops to be controlled from PLC-generated digital values.
The module design includes PLC-5 I/O density scaling characteristics through four-channel analog output integration. The conformal coating provides a protective layer over electronic assemblies for installations where humidity and corrosive chemical exposure may affect circuit surfaces. The module is configured with installed jumpers, allowing operation without additional operator configuration before activation.
Frequently Asked Questions
Q: What type of analog signals does the 1771-OFE3 generate?
A: The module provides four differential analog current outputs with a 0-50 mA output range.
Q: Does the 1771-OFE3 require an external field power supply?
A: No. The module operates from the PLC-5 backplane interface and does not require an external power source.
Q: What isolation method is provided between output channels?
A: Each analog output channel is individually isolated with a rated isolation voltage of 1000 V.
Field Installation Guidelines
Install the 1771-OFE3 module in a compatible PLC-5 1771 I/O rack following the chassis slot assignment and keying requirements. Confirm backplane power availability before inserting the module.
Connect analog field wiring through the specified 1771-WH wiring arm. Use shielded cables for low-level current signal circuits where electromagnetic interference may affect measurement stability. Terminate cable shields according to the site grounding standard and avoid multiple ground points that may introduce ground loops.
Route analog output wiring separately from high-voltage power cables, motor conductors, and switching devices. Verify channel isolation requirements before connecting external field instruments.
