KL1154, KL1164 | 4-channel digital input terminals 24 V DC, switching to positive and negative potentials
The KL1154 and KL1164 digital input terminals acquire the binary control signals from the process level and transmit them, in an electrically isolated form, to the higher-level automation unit. The KL1154 and KL1164 versions have input filters of different speeds. Sensors that switch to the positive potential or to 0 V (ground) can be connected to the KL1154 and KL1164 versions. The Bus Terminals contain four channels that indicate their signal state by means of light emitting diodes.
