Figure 4.8.
Example of digital output relay power supply connections.
Each relay allows independent pole switching; it can thus control the switching on/off of the units, including those powered with a
different voltage. The capacity of the relays is 8A/250Vac per pole. If the equipment to be controlled exceeds this capacity, an
external relay or contactor must be installed. Shown below are examples of connections between circulator pumps and 3-way
valves with controls at 2 or 3 points.
NOTE
Pay special attention to the maximum consumption allowed by each relay. Use an intermediate
relay or a contactor for the connection, if necessary.

Power supply
The supervisor only requires one electrical connection. The power supply to the 24Vac transformer connects to it to power the
controller and other devices with low power consumption. The following table shows the characteristics of the necessary electrical
connection:
