Digital input module KL1488

8 digital inputsmulti-channel16 digital inputs

Product overview
The KL1488 digital input terminal acquires binary 24 VDC control signals at the process level and transmits them, electrically isolated, to the higher-level automation unit. The bus terminal provides eight channels with individual LED status indicators. All inputs use the 24 VDC supply contact as reference; the power contacts are connected through.

Features

• Ground switching (0 V switching)
• 3 ms input filter to suppress contact bounce from mechanical switches
• Direct connection of multi-channel sensors using 1-wire connection technology
• Electrically isolated signal transmission to the automation unit
• LED indication for each channel

Variations

• 8 inputs (this product variant)
• 16 inputs (alternative variant)
