2-Channel 120/230 V AC Digital Input Terminal

Product Description

The KL1702, KL1712 and KL1722 digital input terminals acquire the binary control signals
from the processing level and transport them as electrically isolated signals to the
higher-level control system. Direct connection of 120 V / 230 V AC actuators is possible.
The bus terminals contain two channels each, which indicate their signal status by LEDs.
The KL1722 variant has no power contacts. In this way individual potential groups can be
constructed.
