4-Channel 24 V DC Digital Input Terminal
Product Description

The KL1154 and KL1164 digital input terminals acquire the binary control signals from the
process level and transport them as electrically isolated signals to the higher-level
control-system. Sensors that are positive or negative 0 V (earth) switching can be
connected to the KL1154 and KL1164 variants. The KL1154 and KL1164 have different filter
delays. The bus terminals contain four channels each, which indicate their signal status
with LEDS.
