SRT2

Fast and easy over CompoBus/S

Omron’s unique CompoBus/S is the most efficient I/O bus for machine automation. With free topology and up to 500 m bus length in long-distance mode, it can be used as a remote I/O system. In high-speed mode
(100 m max.) the guaranteed sub-millisecond cycle time makes it ideal for efficient machine control. Used with the compact CPM2C-S PLC as master, your machine control system will fit in the smallest spaces.

Compact size in IP20 housing
Fast cycle time; less than 1 ms per 256 I/O points
Easy set-up; no software required
Choice of 4- 8- and 16-point Digital I/O; transistor-, and relay models
Analog In/Outputs and customisable modules available
