MReX-Multi Telemetry I/O Expansion Module
The MReX Multi-IO is a 16-input 16-output addressable digital IO module with RF and RS422/485 serial connectivity. This product is ideally suited towards applications that require either an expansion to the PLC capabilities of the TReX-PLC or remote monitoring and control of large amounts of I/O. The MReX Multi-IO provides flexibility and customisability to suit the needs of many different projects. The MReX-Multi can operate as a POCSAG paging transceiver, and can directly message POCSAG pagers or DMR radios.
Flexible IO Expansion
Many IO configurations are possible. Expansion is possible up to 10 units directly wired via RS422, or an unlimited number of wireless units - allowing for system support of any number of inputs or outputs. Because the MReX-Multi also acts as a standalone paging transmitter, messages can be sent directly to a pager or DMR radio, meaning that a complete system could be a simple as a single MReX-Multi and a receiving belt pager or DMR radio. The MReX-Multi is well suited as a POCSAG output control module for simple telemetry control applications.
As an example, a central control unit (either a Multi-IO unit or a TReX-460) needs to control the outputs of 5 units remotely via RF link. The remote units consist of one RS422 master unit that maintains an RF link with the control unit and 4 RS422 slave units which report their I/O to the RS422 master unit.
