KL1184 | 4-channel digital input terminal 24 V DC, switching to negative potential

The KL1184 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 0 V (ground) can be connected to the KL1184. The Bus Terminal contains four channels that indicate their signal state by means of light emitting diodes.
