Information About 1746-IB32
The 1746-IB32 is part of the SLC 500 digital I/O family and provides thirty-two sinking input points for monitoring discrete field signals. It operates within defined voltage ranges depending on ambient temperature and maintains consistent input performance with typical input currents around 5 mA at 24 VDC. This module features complete channel isolation from the backplane, tested at 1500 VAC, ensuring robust electrical protection. Designed for modular and remote SLC 500 systems, the 1746-IB32 utilizes removable terminal blocks for streamlined wiring and simplified field replacement, making it suitable for distributed control and general-purpose automation tasks.
Key Features
- High-Density 32-Point Input Module: Supports up to thirty-two sinking 24 VDC field inputs.
- Broad Input Voltage Range: Accepts 15–30 VDC at 50 °C and 15–26.4 VDC at 60 °C.
- Fast Response Time: Provides 3 ms delay for both OFF-to-ON and ON-to-OFF transitions.
- Backplane Isolation: Dielectric withstand of 1500 VAC for enhanced electrical protection.
- Removable Terminal Block Design: Simplifies field wiring and module replacement.
- Compatible with All SLC 500 Chassis: Installs in local, expansion, or remote racks (except slot 1).
- Wide Environmental Ratings: Operates from 0–60 °C with resistance to vibration and shock.
- General-Purpose DC Input Capability: Supports switches, sensors, and discrete devices.
The 1746-IB32 delivers the reliability and precision required for high-density digital monitoring in SLC 500 automation systems.
