The KL1498 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 contains eight channels, whose signal states are indicated by light emitting diodes. The KL1498 has the 24 V DC power contact as the reference point for all inputs. The power contacts are connected through.
Special features:
- ground switching
- low delay due to 0.2 ms input filter
- direct connection of multi-channel sensors in 1-wire connection technology in the smallest space
Product status:
regular delivery
