12-13. Relay selection for the pump control connection
The maximum current capacity of T-K3’s pump control connection is 1 amp
.
Before using any relay w ith the pump control, please check the specifications of that particular
relay to ensure that the current value through the coil w ill not exceed 1 amp.
For example:
To the r ight, there is a sample of relay
specifications from an arbitrary brochure.
You can select either the 120VAC or 240VAC
relay, because their current values are less
than 1A (1,000mA).
Through this circuit, the
m axim um current capacity is 1A
Typically
120VAC
