KL1404 | 4-channel digital input terminal 24 V DC
The KL1404 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 corresponds to EN 61131-2 type 3 and is compatible with type 1. Additionally, the 4-channel Bus Terminal enables the direct connection of four 2-wire sensors. Four +24 V connection points are provided.
