Storage: -40°F to 185°F (-40°C to 85°C); 5% to 95% RH noncondensing


BACnet® MS/TP: valid field controller device addresses 4 to 127. Device addresses 0 to 3 and 128 to 255 are reserved and not valid field controller addresses.

N2: valid field controller device addresses 1 to 255.

Communications bus

BACnet® MS/TP:

3-wire zone bus between the supervisory controller and the field controller.

3-wire sensor bus between the controller, network sensors, and other sensor and actuator devices. Includes a lead to source 15 VDC supply power from the controller to bus devices.

Processor RX631 Renesas® 32-bit microcontroller
Memory 16 MB flash memory and 8 MB RAM
Input and output capabilities
Five universal inputs, application-specific, three available modes:
  • Voltage input: 0 VDC to 10 VDC
