The BM-CRIO-20P series is aimed at affordable canned solutions for standalone applications, such as roof top units, fan coils, AHU’s, package units, etc.

The BM-CRIO-20P is the first product in the CRIO range, designed to complement the BM-CMP-30P and the awarding winning BM-CH series. All of the CRIO series products are equipped with two RS485 ports. For Ethernet applications you can upscale to the 30P or one of the BM-CH series controllers. All BM-CRIO products are BACnet and Modbus selectable and can be programmed live and free via Programming Tools.

The CRIO-20 has 20 points of I/O and is priced to meet most high volume applications and price points. The microprocessor based controller has 20 I/O to accommodate general and specific applications featuring BACnet MSTP and Modbus RTU communication protocols. The 20 IOs include, 12 Universal Inputs (UI) supporting current, voltage and resistance based sensor, 4 electrically isolated Digital Outputs (DO) and 4 Analog Outputs supporting current and voltage outputs.
