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 one module (input signals) are transmitted to other modules where the signals are re-created as output signals or passed via a data bus to a host device such as a PLC, DCS or SCADA system. Expandable up to 16 Expansions. 32 bit RISC RTU Processor. Can be configured as Modbus Master / Slave. Third party device interface on serial / Ethernet port. DC powered unit (24VDC).
