Product Name: BECKHOFF KL1408 -Channel Digital Input Terminal Product Brand: BECKHOFF Product Code: KL1408 Product Artikel: BECKHOFF KL1408 -Channel Digital Input Terminal
The 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.
