E2C
E2C-WH4A(F)
The E2C-WH4A(F) has NPN and PNP open collector outputs. Therefore, there is a degree of freedom in load types and power supply polarity.

on the load if the load is connected to an
independent power supply.
E2C-AK4A, E2C-AM4A
The E2C-AK4A has relay contact and transistor photocoupler outputs and the E2C-AM4A has NPN and PNP open collector outputs. There-
fore, there is a degree of freedom in load types and power supply polarity.
