Features:
- Forty embedded I/O points combine 24 DC inputs with 16 relay outputs.
- Operates from a 100 to 240 V AC supply and provides 6 KB of controller memory.
- The RS-232C port supports documented DF1, DH-485, Modbus RTU and ASCII communication.
The 1762-L40BWA combines a MicroLogix 1200 processor, AC power supply and forty embedded I/O points in one compact controller. It accepts a 100 to 240 V AC supply and provides 24 embedded 24 V DC inputs, including four fast inputs, together with 16 relay outputs and 6 KB of controller memory for machine and small-process applications.
Its RS-232C communication port supports the documented DF1, DH-485, Modbus RTU and ASCII modes for connection to compatible programming, operator-interface and field devices. Replacement requires the application and data, controller series and firmware, input commons, relay supply groups, expansion-I/O order, power budget and complete serial protocol settings to be recorded and restored.
The 1762-L40BWA Allen-Bradley MicroLogix 1200 40-point Controller may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
