The Allen-Bradley 1794-IV32 is a high-density discrete input module within the Flex I/O platform, ideal for distributed I/O topologies, featuring 32 current sourcing input channels compatible with 24 VDC nominal signals. Designed for seamless integration in industrial environments, it offers configurable filter times, enhancing signal accuracy by eliminating noise-induced false activation, and operates efficiently with a FlexBus current draw of 40 mA at 5 VDC. Securely installed via an alignment bar and latching mechanism, this module is equipped with 32 status indicators for alerting users to operational conditions and must be grounded appropriately using a zinc-plated chromate-passivated steel DIN rail for optimal performance.
