AutomationDirect has added more I/O expansion modules to its BRX Micro PLC product line. BRX I/O expansion modules add digital and analog I/O as needed to expand machine and process control applications. BRX expansion modules snap onto the side of any BRX Micro PLC Unit (MPU) or the BRX Remote I/O controller.

Three 32-point discrete I/O and five analog I/O expansion modules as well as three new temperature input modules have been added. Three 4-channel analog input and two 4-channel analog output modules are now available with current and voltage signal options.

Current signal ranges are 0-20 mA, 4-20 mA; voltage ranges are 0-5 VDC, 0-10 VDC, +/- 5 VDC, +/- 10 VDC. Max input and output signal resolution is 16-bits.

Also added are 8-channel Thermocouple input, 6-channel RTD input and 8-channel Thermistor input modules; all with 16-bit resolution.
