BRX micro PLC modules include digital and analog I/O as needed to expand machine and process control applications. The 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 have been as well as three temperature input modules. Three four-channel analog input and two four-channel analog output modules are available with current and voltage signal options. Current signal ranges are 0-20 mA and 4-20 mA; voltage ranges are 0-5 Vdc, 0-10 Vdc, ±5 Vdc and ±10 Vdc.
