The KL1124 digital input terminal acquires the binary 5 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 four channels that indicate its signal state by means of light emitting diodes. The 5 V supply voltage can be generated with the power supply terminal and fed into the power contacts.
Special features:
- 5 V inputs
- low delay due to 0.2 ms input filter
- +5 V and 0 V DC sensor supply connections
