Hitachi X200 Series Using Intelligent Output Terminals, Sinking Outputs, Open Collector

Using Intelligent Output Terminals

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 two physical logic outputs. One of the outputs are open-collector transistors, and the other output is the alarm relay (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 use.

Sinking Outputs, Open Collector

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 100mA to drive both outputs at full load. To drive loads that require more than 50mA, use external relay circuits as shown to the right.

Sinking Outputs, Open Collector

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.
