MicroBrick Distributed I/O Modules

MicroBricks provide larger blocks of modular distributed I/O in a very compact package. A unique built-in operator interface saves time during installation and system troubleshooting. MicroBricks can be used as I/O expansion slaves to a PLC or PC Host, as SCADA system RTUs, or to “mirror” analog and discrete signals over long distances. MicroBricks support radios, leased line modems, RS-232 and RS-485 communications.
