Description
Designed for integration into industrial K-bus systems, the BECKHOFF KL4032 analog output terminal generates high-precision signals across a range of -10 to +10 V. This industrial-grade module features two single-ended analog output channels with a 12-bit resolution, ensuring accurate transmission of control values to actuators, valves, variable speed drives, and other process control components.
The KL4032 is designed with short-circuit proof outputs and provides electrical isolation between the internal K-bus and the signal field lines. Highly integrated and compact, this terminal is powered directly via the K-bus, eliminating the need for additional power contacts. It is fully compatible with standard Beckhoff KSxxxx pluggable wiring systems, simplifying maintenance and installation inside control cabinets.
Features
- Two single-ended analog output channels for -10 to +10 V signals.
- 12-bit digital-to-analog resolution for reliable process control.
- Short-circuit proof signal outputs with a minimum load impedance of 5 kOhm.
- Complete galvanic isolation up to 500 V between the internal K-bus and the signal electronics.
- Direct power supply through the internal K-bus connection (75 mA typical current consumption).
- No hardware address or complex manual configuration settings required.
Applications
- Power generation and distribution facility automation.
- Oil and gas refinery process control loops.
- Water and wastewater plant automation systems.
- Pneumatic and hydraulic valve actuator control.

Installation Guidelines
The BECKHOFF KL4032 is designed for variable mounting on standard 35 mm DIN rails (EN 60715). Ensure correct interlocking of K-bus terminal side-guides to guarantee continuous communication. For optimal noise rejection in high-interference environments, use shielded cables and ground the shield at the entry point of the control panel. Do not block the ventilation slots to maintain the operating temperature below 60 degC.
