Product Name: BECKHOFF KL 1408 Channel Digital Input Terminal Product Brand: BECKHOFF Product Code: KL 1408 Product Artikel: BECKHOFF KL 1408 Channel Digital Input Terminal
channel digital iThe digital input terminal KL1408 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 eight channels which indicate their signal state by means of light emitting diodes. It is particularly suitable for space-saving use in control cabinets. By using the single-ended connection technique, a multi-channel sensor can be connected in the smallest space with a minimum amount of wiring. The power contacts are looped through. For the KL1408, the reference ground for all inputs is the 0 V power contact.
