Description

Process control and automation networks requiring precise analog current loop signals utilize the Beckhoff KS4012 analog output terminal to interface with industrial actuators. This 2-channel analog output module delivers accurate signals in the range of 0 to 20 mA with a high-accuracy conversion resolution of 12 bits. The KS-series configuration features a pluggable wiring level, enabling rapid block installation, simplified maintenance, and field-pre-wiring without disconnecting individual signal lines. The module processes electrical analog current signals dynamically by converting digital values from the K-bus backplane with galvanic isolation, ensuring signal integrity in electrically noisy industrial environments.

Features

Two-channel analog outputs configured for standard 0 to 20 mA current loops.
High-resolution 12-bit digital-to-analog signal conversion.
Pluggable connection level (KS series design) for tool-free terminal replacement.
Galvanic isolation of 500 V between the K-bus and the analog process loop.
Compact 12 mm DIN rail housing to minimize control cabinet footprint.
Automatic data transfer across the K-bus with no address configuration required.

Applications

Proportional control valves and pneumatic actuators.
Speed references for variable frequency drives (VFD) and motor controllers.
Current-loop signal transmission in municipal water and wastewater systems.
Process heating loops and environmental chamber control.

Key Features:

What is the key advantage of the KS4012 compared to the KL4012?

The KS4012 features a pluggable wiring connection level, allowing the terminal blocks to be quickly removed for maintenance without rewiring, whereas the KL4012 uses standard fixed terminals.

Does the KS4012 require manual address configurations?

No, the KS4012 requires no address or manual DIP switch configurations; it automatically maps its process image parameters via the K-bus backplane.

Can I power the KS4012 with a 15 V DC source?

Yes, while the standard power supply is 24 V DC via the power contacts, the KS4012 can be alternatively supplied with 15 V DC using a KL9515 power supply terminal.

What standard environmental protection rating does the KS4012 have?

The terminal is rated at IP20 and should be installed within a control cabinet or protective enclosure.
