Digital input module KL1889

8 digital inputs16 digital inputsvoltage

Product overview
The KL1889 digital input terminal acquires binary 24 VDC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The bus terminal contains sixteen channels whose signal states are indicated by LEDs. Power contacts are connected through; the reference ground for all inputs is the 24 VDC power contact.

Key features

• Sixteen channels (bus terminal) with individual signal-state indication by LEDs
• Acquires binary 24 VDC control signals
• Electrically isolated transmission to higher-level automation unit
• Through power contacts; input reference ground is the 24 VDC power contact
• Ground switching capability
• 3 ms input filter to prevent contact bouncing from mechanical switches
• Tool-free connection by direct plug-in technology for solid wire conductors
• Space-saving design for installation in control panels
• Direct connection of multi-channel sensors using 1-wire connection technology

Variations

• 8 inputs
• 16 inputs (this page)
