Main Features and Advantages
Mixed-load flexibility with relay contacts: The standout feature of the 1762‑OW16 is its ability to handle both AC and DC loads on the same module without external conversion devices. Each output is a dry contact that can switch 24V DC logic circuits, 120V AC indicator lamps, or 240V AC motor starters (within current limits). This eliminates the need for separate transistor (DC) and triac (AC) output modules in compact control systems, significantly reducing cabinet space and BOM complexity.Cost-effective expansion for small PLCs: As a 1762-series module, it connects directly to the right side of MicroLogix 1100/1200/1400 controllers via a ribbon cable, creating a seamless I/O chain. With 16 points in a compact form factor, it offers a high point density for relay-based control, making it a budget-friendly solution for adding discrete outputs to a base controller that has run out of onboard capacity.
Application Field
The 1762‑OW16 is widely used in small to mid-size industrial machines requiring versatile output control. Typical applications include material handling conveyors (controlling motor contactors and DC brake releases), packaging machinery (actuating solenoids and heaters), and HVAC control panels (switching fans and dampers). Its relay outputs are particularly suited for interface applications where the PLC must drive loads of varying voltages or provide complete electrical isolation between the control logic and the power circuit.
