Smart Relays With Modular I/O Scale to 48 Points on DIN Rail
Monitoring and controlling small to mid-size systems often demands a balance between compact footprint and the flexibility to scale as application requirements change. The Altech Smart Relay series addresses both with a modular, DIN rail-mounted control solution available in AC and DC base versions, designed for real-time monitoring and control without requiring prior programming knowledge.
The relays ship in a 3 x 3.5 x 2.5 in (72 x 90 x 65 mm) housing that snaps directly onto a DIN rail. Free configuration software allows users to generate programs, project simulations, and documentation through an interface that requires no prior programming background. A communication module adds Modbus protocol support for high-speed, real-time monitoring and compatibility across a broad range of devices.
Each unit starts with 8 inputs and 4 outputs, with support for up to 3 expansion modules that bring total I/O capacity to 48 points—32 digital inputs and 16 digital outputs—allowing users to scale up as application demands grow.
Also available is a universal multitimer offering two or 10 timing functions, a timing range of 0.1 s to 100 h, an LED indicator for power and relay status, DIN rail compatibility, and a 17.5 mm (0.7 in) width.
