2-Channel 24 V DC Digital Input Terminal

Product Description

The KL1052 digital input terminal acquires the binary control signals from the process
level and transports them as electrically isolated signals to the higher-level control
system. Sensors that are positive or negative (0 V) switching can be connected to the
KL1052 variant. The bus terminal contains two channels, which indicate their signal states
with LEDs.
