- Installs in the leftmost slot of a 1771 I/O chassis
- Requires 1.25 A from the chassis backplane
- Uses a self-contained lithium battery to retain memory for one year without AC power
1772-LX serves the Mini-PLC-2/16 configuration with a documented capacity of up to 256 I/O points.
Half-slot, one-slot, or two-slot addressing changes the I/O image, making the installed rack map essential replacement information.
The processor, external power design, EEPROM image, and saved application must be treated as one matched system rather than independent parts.
Availability, condition, price, and shipping time for 1772-LX are confirmed during quotation.

- The official manual identifies 1772-LX as the Mini-PLC-2/16 processor.
- Mini-PLC-2/16 supports the documented maximum of 256 I/O.
- The non-powered LX catalog must match the cabinet power arrangement.
- Half-slot, one-slot, and two-slot addressing are documented for the processor family.
- The addressing selection determines how field modules map into the I/O image.
- The saved program and any EEPROM image must use the installed addressing mode.
- Preserve the complete application before removing processor power.
- Confirm chassis, external supply, EEPROM, and I/O layout against the machine records.
- Prove inputs, controlled outputs, and processor diagnostics before return to service.
- Legacy Mini-PLC-2/16 systems requiring the documented 256-I/O capacity.
- PLC-2 machine-control maintenance with retained rack addressing and application data.
- Like-for-like processor replacement where the external power design remains unchanged.
