Beckhoff KL9020 Digital Output Terminal Module
Product Introduction
The Beckhoff KL9020 is a digital output terminal module designed to
connect binary control signals from automation units to
process-level actuators with electrical isolation. Operating at 24
V DC, it features eight output channels, each protected against
reverse polarity, overload, and short-circuit. The module indicates
signal states via LED indicators and is optimized for space-saving
installation in control cabinets. With loop-through power contacts
and a 2 A short-circuit current rating, it ensures reliable
operation in industrial automation setups, requiring a common
reference point with connected components.
Product Features
Electrical Isolation & Protection:
500 V electrical isolation between power contacts, supply voltage,
and K-bus.
Reverse polarity protection, overload/short-circuit protection for
each output channel.
Output Specifications:
8 digital output channels with LED status indicators.
Nominal voltage: 24 V DC (-15%/20%); short-circuit current: 2 A per
channel.
Breaking energy: <150 mJ/channel for safe switching.
Power & Connectivity:
Power contacts looped through for daisy-chaining; 24 V DC supply
via power contacts.
Single-ended input connection technology for simplified wiring.
Space-Saving Design:
Compact form factor suitable for dense control cabinet
installations.
Reliability & Diagnostics:
LED indicators for real-time channel status monitoring.
Common reference point requirement ensures signal integrity with
connected components (e.g., KL2408).
