Technical Specifications

Engineering Advantages

Space-Saving Combination Architecture
The 1746-IO12DC maximizes your SLC 500 chassis capacity by combining 6 inputs and 6 outputs into a single I/O slot. This design drastically reduces the physical footprint required for your control system, allowing you to fit more functionality into smaller control panels and minimizing the overall hardware costs of your automation project.

Optimized 24V DC Industrial Control
Engineered for standard industrial logic levels, this module operates seamlessly within a 10-30V DC range. Each of the 6 output channels delivers up to 1.2 amps of current, providing ample power to directly drive solenoids, indicator lights, and small contactors without the need for external intermediate relays.

Efficient Backplane Integration
Drawing only 60-80 milliamps from the SLC 500 backplane, the 1746-IO12DC maintains high energy efficiency. This low power consumption ensures stable operation across your entire PLC rack, preventing power supply overloads even when multiple combination modules are installed side-by-side.
