12-15. Relay selection for the pump control connection
The maximum current capacity of T-H2-DV or T-H2-OS pump control connection is 1 amp.
Before using any relay with the pump control, please check the specifications of that particular relay to
ensure that the current value through the coil will not exceed 1 amp.
For example:
To the right, there is a sample of relay
specifications from an arbitrary brochure. You
can select either the 120 VAC or 240 VAC relay,
because their current values are less than 1 A
(1,000 mA).
