The Pertronic R2H Relay Board (or Relay2 Board) contains two transistor-assisted relays, and it has been designed for connection to Pertronic F16e, F100 and F120 Panels. An Isolate Switch is provided for when Local Isolation of the relays is required. The Switch is also protected by an Interlock Connection. 

Two Inputs are available for controlling each relay. IN1 connections control the operation of Relay 1, and IN2 connections control the operation of Relay 2. 

Each relay provides change-over contacts (no-c-nc), rated 5 A, 30 Vdc, and each relay state is indicated by an on-board Green LED. The relay contacts are not monitored.
