Using Intelligent Output Terminals

Operations and Monitoring

The intelligent output terminals are programmable in a similar way to the intelligent input terminals. The inverter has several output functions that you can assign individually to five physical logic outputs. Along with these solid-state outputs, the alarm relay output has type Form C (normally open and normally closed) contacts. The relay is assigned the alarm function by default, but you can assign it to any of the functions that the open-collector outputs can use.

TIP: The open-collector transistor outputs can handle up to 50mA each. We highly recommend that you use an external power source as shown. It must be capable of providing at least 250mA to drive the outputs at full load.

If you need output current greater than 50mA, use the inverter output to drive a small relay. Be sure to use a diode across the coil of the relay as shown (reverse- biased) in order to suppress the turn-off spike, or use a solid-state relay.
