Wireless serial communications system
Omron’s WT30 Wireless Serial Communications system eliminates barriers to communicating with moving equipment, retrofitting networking on running devices, and evading obstacles where wiring is impractical.
The WT30 system consists of one master and multiple slave I/O stations with expansion capability for up to 64 slaves (over 1,000 I/O). The wireless serial master collects ON/OFF data and provides an RS-232C (CompoWay/F) interface to a personal computer or PLC. Pre-tested function blocks in CX-One software simplify WT30 communications setup using Omron’s CS, CJ and CP1 families of PLCs. The I/O slave terminals are available with 16 inputs or a combination of 8 inputs and 8 outputs. Antennas for slave stations, cables and mounting brackets are ordered separately to match installation requirements. The WT30 conforms to FCC part 15.247 (USA) and international standards.
