circuit is isolated from the internal control circuit by photocoupler.
• In the source logic, terminal PC is a common terminal for the contact input terminals (RES, OH, RDI). The open collector
circuit is isolated from the internal control circuit by photocoupler.
• Terminal SE is a common terminal for the open collector output terminals (RDA, RDB, RSO, IPF, FAN). The contact input
circuit is isolated from the internal control circuit by photocoupler.
