Appendix 3: External Relays

The relays on the alpha TDS 200 series controller are rated for 6 amps at 110 VAC and

can be wired directly to your final control element (provided its power requirements does

not exceed this). However, to preserve the life of your controller, or if higher power is

needed, it is recommended that you use the controller relay to drive an external relay.

Diagram below shows a typical installation. Wiring should be changed appropriately if

normally closed (N.C.) operation is desired.
