New expansion I/O modules from AutomationDirect for the BRX stackable micro brick PLC include communications modules, universal analog I/O modules, and universal temperature combination I/O modules. Expansion modules snap onto the side of any BRX Micro PLC Unit (MPU) or BRX Remote I/O controller, creating a sturdy and rugged PLC platform.
Added BRX serial communications modules provide four isolated RS-232 ports that
Automation Direct's BRX stackable micro brick PLC
support communications-flow control or RS-422 serial ports. Also available are BRX single-channel RS-232 (with flow control) and RS-422 Pluggable Option Modules. Supported protocols include Do-more! Protocol, Modbus RTU (Master/Slave), K-Sequence, and ASCII (In/Out). Data rates are 1200 to 115,200 bps.
Universal analog I/O modules have combined current and voltage options. Universal temperature modules provide thermocouple, mV level voltage, RTD or thermistor selection with 24-bit resolution. The 4-channel combination temperature I/O expansion module has universal temperature inputs and analog outputs. Four-channel combination temperature input / discrete output modules provide universal temperature inputs and discrete sink, source or relay outputs.
