KL1124 | 4-channel digital input terminal 5 V DC
The KL1124 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 Bus Terminal contains four channels that indicate their signal state by means of light emitting diodes. The 5 V supply voltage can be generated with the KL9505 power supply unit terminal, and fed into the power contacts.
