Product Name: BECKHOFF KL1704 Channel Digital Input Terminal Product Brand: BECKHOFF Product Code: KL1704 Product Artikel: BECKHOFF KL1704 Channel Digital Input Terminal
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. It is possible to connect 120 V/230 V AC sensors directly. The Bus Terminal contains four channels that indicate their signal state by means of light emitting diodes.
