SenTRI 4 Channel Mains Switching Interface Unit

The SenTRI 4 channel mains switching Interface units connect directly to the loop of SenTRI 2 and 4 loop systems. These interface units are designed to provide heavy duty relay switching for both 24V and 230V applications with contacts rated at 13A.

The SenTRI 4 channel mains switching Interface units connect directly to the loop of SenTRI 2 and 4 loop systems. These interface units are designed to provide heavy duty relay switching for both 24V and 230V applications with contacts rated at 13A. These interface units are particularly suitable for switching damper control units and other building controls requiring a high contact rating for mains shutdown. These units are operated in various modes such as input, output, input and output, input with confirmation output, and output with confirmation input, etc.

Features & Benefits:
  • Flexible input or output
  • Controlling outputs and monitoring inputs simultaneously
  • Configurable delay to filter noise and spurious signals
  • Outputs can be individually sectored
Certifications:
  • EN54: Part 17 and EN54: Part 18
