2.2.3
Relay Outputs
The four Form A (SPST-single pole single throw) normally open relay outputs can control a
wide range of devices such as motor starters, solenoids, and indicators. Power for the
internal relay coils is provided by the +24-volt DC internal supply. An external source of AC
or DC power must be supplied to operate field devices.
The relay outputs can be used as up to three High-Speed Counter outputs. They cannot be
used as Pulse Train or Pulse-Width Modulated outputs. Connections and specifications for
High-Speed Counter outputs are the same as for standard relay outputs.
