Beckhoff KL1104

Beckhoff KL1104 Digital Input Terminal

The KL1104 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 four channels that indicate its signal state by means of light emitting diodes.
