Beckhoff Automation kl1232

The KL1232 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal has two channels, whose signal state is displayed by light emitting diodes. The KL1232 has an input circuit that extends positively switched signals to 100 ms. The trigger takes place on the positive edge. The Bus Terminal is particularly well suited for the acquisition of very short signals in control systems with a longer processing time than the signal length.   Special features: low delay due to 0.2 ms input filter edge-controlled pulse extension of 100 ms   In addition to the KL1232, there are other KL1232-xxxx versions with pulse extension of 10, 20, 100 or 200 ms 3 ms or 0.2 ms input filter positive or ground switching logic positive or negative edge-triggered inputs
