Relay Outputs

Each relay output is rated at 24 Vac or Vdc at 0.5A. Relay outputs have MOV (metal oxide varistor) suppressors to
support inductive-type loads such as heavy-duty relay coils.
Relays are not rated for AC mains (line level) powered loads (instead, 24V maximum).
Warning
Use an external 24V transformer or a 24Vdc power supply to power loads.
Use a RelayOutputWritable in the station for each output.
