Isolation Relay (optional)
The Form C relay can control a device that draws less than 10Amps of current. If
a device draws more than 10Amp of current, or the sum of all devices controlled
by the Form C relay exceeds 10Amps, an isolation relay must be used. Refer to
Figures5 and 6 for isolation relay wiring.
