KL1408 | Bus Terminal, 8-channel digital input, 24 V DC, 3 ms, 1-wire connection
The KL1408 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. Each Bus Terminal contains eight channels which indicate their signal state by means of light emitting diodes.
Special features:
- input specification type 1/3
- no bouncing due to mechanical switches thanks to 3 ms input filter
