This 40-point controller module provides a balanced I\/O architecture, featuring 24 discrete inputs and 16 discrete relay outputs, making it an ideal choice for machine control, process monitoring, and localized automation tasks where space and reliability are critical.\u003c\/p\u003e\n\u003cp\u003eEngineered with versatility in mind, the 1762-L40BWA accepts an AC input power range of 100-240V AC, allowing it to function in diverse global power environments. Its input section supports both sinking and sourcing wiring configurations, providing engineers with the flexibility needed to interface with various sensor types, including those requiring 24V DC. The output section is equally adaptable, featuring mechanical relay contacts that support a wide range of switching voltages—from 5V up to 265V AC or 125V DC—ensuring compatibility with standard contactors, motor starters, and solenoid valves. With an integrated RS-232 communication port supporting multiple industrial protocols like DF1, Modbus, and DH-485, the 1762-L40BWA excels as a standalone controller or as part of a broader, networked industrial control system.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr
