The Single Relay Module (SRM) enables a controller output signal to drive a single changeover relay. The 2SRM houses two single relays. |

The Two Relay Module (2RM) may be configured as a high/low or a raise/lower relay module by link selection. |
| • |
The Three Relay Module (3RM) may be configured as a Fan/Heating/Cooling sequence controller (HCM) or a 3 stage sequence controller (TRM) using the operating mode link. |

The Six Relay Module (6RM) converts an analogue output of an IQ controller to six stages of relay output. |
| • |
The Voltage to Current Driver is a two channel output interface which converts two 0 to 10V signals into two 0 to 20 mA outputs. |

The Latching Relay Module (LRM) is designed for two applications:- 1) to enable an audible alarm to be generated by a communications node on receipt of a message. 2) to provide instantaneous action when a contact is pulsed. |
| • |
The Dual Phase Cut Module converts two controller analogue output signals to two 20 V phase cut signals for controlling valves and actuators in heating and ventilating equipment. Opto-isolation is used to isolate the control signals from the outputs to ensure that no ground conflicts can occur. |
