Features:
- 24-point controller: DC input groups with ten relay outputs
- High-speed sensing: four inputs support the documented fast counter path
- Service interface: Channel 0 serial communication with DCOMM recovery control
1762-L24BWA supports MicroLogix 1200 equipment that needs DC sensing and relay actuation from an AC-powered controller.
Its high-speed input group, relay commons, sensor supply, and serial recovery controls have distinct roles that must be retained during service.
For discontinued-system support, the exact L24BWA suffix should remain tied to the project, firmware, memory module, serial settings, terminal schedule, expansion bank, and tested machine behavior.
Apter Power can coordinate official-document checks, quotation, and sourcing support for 1762-L24BWA.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Fast group: use inputs 0…3 for qualified high-speed counting within the configured filter boundary.
- Standard group: place ordinary sensor states on inputs 4…13 and account for scan-dependent response.
- Polarity: wire the two DC input groups for the approved sinking or sourcing arrangement and verify commons at the terminals.
- Terminal groups: map every relay common and field voltage from the official L24BWA diagram.
- Load protection: apply qualified suppression to inductive relays, contactors, starters, and solenoids.
- Release test: prove on, off, program, and fault behavior under representative load before returning the machine to service.
- DCOMM control: use the communication-toggle function to distinguish a user configuration fault from a hardware communication fault.
- Protocol record: preserve DF1, DH-485, Modbus RTU, or ASCII settings together with the correct cable and peer role.
- Expansion bank: verify Bulletin 1762 module order and complete the system-loading worksheet before reconnecting up to six modules.
- Compact discrete machines: monitor 24 V DC sensors and switch qualified relay loads.
- High-speed counting: use the first input group for documented pulse or event-counting tasks.
- Serially connected equipment: exchange controller data through the supported Channel 0 protocols.
