KL1154 | 4-channel digital input terminal 24 V DC, switching to positive and negative potentials

The KL1154 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. Sensors that switch to the positive potential or to 0 V (ground) can be connected to the KL1154. The Bus Terminal contains four channels that indicate their signal state by means of light emitting diodes.
