Connection
KL1302, KL1312 | 2-channel digital input terminals 24 V DC for type 2 sensors
The KL1302 and KL1312 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 KL1302 and KL1312 versions have input filters of different speeds. The Bus Terminals contain two channels that indicate their signal state by means of light emitting diodes. The input signal corresponds to the standard IEC 61131-2, type 2. So it is possible to connect 2-wire sensors.
