Capable of controlling multiple pieces of equipment simultaneously, this robust multi-protocol native controller can support complex control strategies with plenty of memory for schedules, alarms and trends.




I/O Pro 812u

The I/O Pro 812u is a general-use controller that can be easily customized to meet any sequence of operation needs. Fully capable of operating in a 100% stand-alone control mode, the I/O Pro 812u can connect to a Building Automation System (BAS) using any of today’s four leading protocols: BACnet (IP, Ethernet, ARC156, MS/TP, and PTP), Modbus (RTU & ASCII), N2, and LonWorks. The point mapping to all of these protocols can be pre-set, so that the protocol and baud rates desired can be easily field-selected without the need for any additional downloads or technician assistance. The I/O Pro 812u provides ample input/output capacity on the base controller, plus support for multiple expansion boards if additional I/O capacity is needed.
