KL1312 | 2-channel digital input terminal 24 V DC for type 2 sensors

The KL1312 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. The Bus Terminal contains two channels that indicate their signal state by means of light emitting diodes. The input signal corresponds to the standard EN 61131-2, type 2. This way, it is possible to connect 2-wire sensors.
