Use
The SRIF is purpose built as a 6 channel 24v powered relay interface module allowing control of 6 independent input / output control interlock circuits. The 6 relays respond to switched 24vAC or DC inputs from external control interlocks that control 6 on board double pole c/o relays. Each relay has 2 c/o sets of contacts which allow connection to 2 output circuits ..ie to operate a drive open/drive close damper motor & an indicating lamp. Each relay is also subject to an on board Auto / Off / Manual control switch to assist in circuit setup & testing.

Technical Data
Electrical Specifications
Input Power Supply 24vAC +/- 10% OR 24vDC +/- 5% @ 8mA per input
Output Indication 6 x 3mm green led (1 per input ) On = Relay energized
Input Terminals 24v sourced from “G” terminal or from an external 24v source but linked & referenced to the “GO” terminal.
Voltage free Relay outputs 1 Amp @ 24vac , 0.5 Amp @ 240v
Note : Due to the close proximity of output circuit board tracks between the different relays and connection terminals etc, and in keeping with Australian electrical segregation safety regulations, DO NOT MIX voltages on the relay connections.
