Bus terminal, 4-channel digital input, 24 V_DC, 2-wire connection

The KL1404 and KL1414 digital input terminals acquire the binary control signals (24 V_DC) and transmit them, in an electrically isolated form, to the higher-level automation system. The bus terminals contain four channels that indicate their signal state by means of light emitting diodes. The KL1404 and KL1414 versions have different input filters. The input signal of KL1404 and KL1414 corresponds to IEC 61131-2, type 1/3. In addition, these bus terminals enable the direct connection of four 2-wire sensors. Four connection points for +24 V are provided.
