KL1404, KL1414, KL1434 | 4-channel digital input terminals 24 V DC

The KL1404, KL1414 and KL1434 digital input terminals acquire the binary 24 V control signals and transmit them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminals contain four channels that indicate their signal state by means of LEDs. The KL1404, KL1414 and KL1434 versions have different input filters. The input signal of the KL1404 and KL1414 corresponds to IEC 61131-2 type 3 and is compatible with type 1. The input signal of the KL1434 corresponds to type 2. Additionally, the 4-channel Bus Terminals enable the direct connection of four 2-wire sensors. Four +24 V connection points are provided.
