KL1434 | 4-channel digital input terminal 24 V DC

The KL1434 digital input terminal acquires the binary 24 V control signals and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains four channels that indicate their signal state by means of LEDs. The input signal of the KL1434 corresponds to corresponds to EN 61131-2 type 2. The 4-channel Bus Terminals enable the direct connection of four 2-wire sensors. Four +24 V connection points are provided.
