Bailey IMDSM05 Digital Input Output Module

The Bailey IMDSM05 Digital Input/Output Module is a Bailey Infi 90 digital I/O slave that interfaces discrete 5/24 V DC signals to a Bailey Infi 90/Net 90 control network, serving as a small, self-contained I/O node within the master‑driven architecture. It connects to the network via a 30‑pin card‑edge connector (P3) and includes front‑panel LEDs that indicate I/O activity for each point, helping operators verify operation at a glance. The IMDSM05 draws about 125 mA, is housed in a compact enclosure measuring roughly 125 × 50 × 30 mm, and weighs around 0.87 kg, making it suitable for installation in control cabinets without excessive footprint. As part of the Infi 90 family, it functions as a digital I/O slave for both inputs and outputs, enabling field devices such as sensors and actuators to communicate with the master controller in real time, with typical use in process automation and sequencing tasks. Documentation describes the module’s input and output circuitry, including transistor‑based outputs and per‑I/O indicators, and notes that on power‑up the outputs may hold off until the master re‑establishes communication, after which the module resumes normal operation within the configured network.
