KL1232 | 2-channel digital input terminal 24 V DC with edge triggered pulse expansion

The KL1232 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The KL1232 has an input circuit that extends plus-switched signals, triggered on the rising edge, to 100 ms. The Bus Terminal contains two channels that indicate their signal state by means of LEDs. The KL1232 is particularly suitable for recording very short signals in control systems with a longer processing time than the signal length.
