One of the unique features of the BRX platform is its ability to expand its capability to fit the application. New analog I/O expansion modules are available in high-resolution current/voltage and temperature models.
Two 8-channel analog current and voltage input modules and two 8-channel current and voltage output modules are available. Current signal ranges are 0-20 mA, 4-20 mA; voltage ranges are 0-5 VDC, 0-10 VDC, +/- 5 VDC, +/- 10 VDC. Input and output signal resolution is 16-bits (external 24 VDC required).
The new 4-channel temperature module supports type J, E, K, R, S, T, B, N, C thermocouples. The module can also be configured for 4-channel millivolt level analog inputs.
These analog expansion modules give the user the ability to add analog I/O as needed for process control applications. Each is clearly identified by the module's front panel color scheme and symbol. Expansion modules easily snap onto the side of any BRX Micro PLC Unit (MPU) creating a rugged PLC platform. Once the expansion module has been snapped in place, the software automatically discovers the I/O with little to no additional setup required. Designer programming software for the BRX PLC is a free download with no key code required.
