The range of wireless I/O provides a alternative to expensive signal wire installations,over short or long distances. Transducer / control signals and PLC signals connected at onemodule (input signals) are transmitted to other modules where the signals are re-created asoutput signals or passed via a data bus to a host device such as a PLC, DCS or SCADA system.
