  • 8 Digital Inputs (dry contact or open-collector)
  • 8 Digital Outputs (relay, N.O.)

The Smart I/O™ Di160 programmable controller incorporates 16 channels of cost effective isolated digital I/O. The I/O is monitored and controlled by a Neuron™ 3150™ Chip with Free topology communication over a LonWorks® network. The Di160 can be utilized in many distributed control applications requiring digital I/O. The I/O of the Di160 makes it perfect for a variety of equipment control applications. The wide operating temperature range, -20 to 70°C, makes the Di160 well suited for many demanding applications.

The eight signal-isolated digital inputs can be used for a variety of functions such as alarm inputs, switch inputs, occupancy sensor inputs, or any other dry contact input. The digital relay outputs can be used to control HVAC outputs, small motors, valves, alarm outputs, lights, or other loads where the current does not exceed 1A at 24 Vac.

The Di160 controller is protected from reverse power supply input wiring, over-voltages, transients, and other common events that can damage unprotected inputs and outputs. User defined algorithms and functions can be programmed using VisualControl, NodeBuilder, LonBuilder or other third party LONWORKS programming tools. The program can be downloaded over the free topology network and is stored in non-volatile memory so it is retained even after loss of power.

The enclosure snaps right onto a 35mm DIN-rail for quick and easy mounting. Its spring-loaded latching mechanism makes it easy to remove.
