7-7-2 Contactor control signal (MC) output circuit
A relay or photo coupler can be driven. When using an inductive load, install a diode.
(Tolerable current: 40mA or less, rush current: 100mA or less)

When using the internal power supply, the power can be directly connected to
VDD if using only the digital output (MC, MBR). When using the digital input
(EMGX), always connect across VDD-COM.
