Two relay boxes are available for use with our TIC controllers:
- A small backing pump relay box is compatible with TIC turbo only and turbo and instrument controllers
- A small backing pump and instruments relay box is compatible with TIC turbo and instrument controllers
The small backing pump relay boxes are able to control mains backing pumps up to RV12/XDS10. The relay box also controls a mains heater band and backing line isolation valve. In addition the small backing pump and instrument relay box includes three 250 V a.c. 3 A changeover relays, which are activated by the gauge open collector set point outputs.
