  • Page 21: Power Supply

    Sharing 24 Vac power between controllers could result in equipment damage. A separate transformer is recommended for each Symbio 500 controller. The line input to the transformer must be equipped with a circuit breaker sized to handle the maximum transformer line current.

  • Page 22: Transformer Recommendations

    Transformer Recommendations The Symbio 500 controller can be powered with 24 Vac or 24 Vdc. You must use a 24 Vac power supply for proper operation of the binary inputs, which require 24 Vac detection, and also to use the spare 24 Vac outputs to power relays and TRIACS.

    DO NOT run input/output wires or communication wires in the same wire bundle with AC power wires. Providing Low-voltage Power for I/Os The Symbio 500 controller can provide low-voltage power to the inputs/outputs. More than one input or output can receive power from a given screw terminal as long as the total amount of power consumed does not exceed the terminal’s limit.
