Schneider Electric AS-B829-116 Fast Input Module

Schneider Electric's AS-B829-116 Fast Input Module is a 16-point TTL-input card designed for Modicon 800-series controllers, delivering fast-response 5 V digital inputs to the PLC. The module accepts standard 5 V TTL signals from sensors, switches, and other digital sources and converts them into PLC-detectable input states for rapid scanning and responsive control. As part of the Modicon I/O family, the AS-B829-116 slots into a compatible I/O rack and interfaces with a Modicon controller to expand discrete input capacity. Each of the 16 inputs is TTL-compatible, with 5 V thresholds suitable for common industrial devices, enabling reliable detection of on/off conditions across a range of industrial environments. Typical applications include real-time digital signaling for machine control, safety interlocks, limit switches, proximity sensor networks, and other input-intensive automation tasks.
