The KL1704 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 direct connection of 120 V/230 V AC signals is possible. The Bus Terminal contains four channels that indicate its signal state by means of light emitting diodes.
Special features:
- direct connection of 120 V/230 V AC signals
- for AC voltage
Product status:
regular delivery
