Beckhoff KS4031 Bus Terminal Analog Output Module

Description

Generating analog control signals within the Beckhoff I/O system, the KS4031 bus terminal delivers a high-precision, single-channel output ranging from -10 to +10 V. This specialized analog output terminal is built with pluggable wiring levels, simplifying installation and maintenance in dense control cabinets. Operating via the standard K-bus, the module isolates control-side logic from field-level actuator signals up to 500 V, providing superior noise immunity and protection for upstream PLC and industrial PC controllers.

Features

• Single-channel analog output with a bipolar signal range of -10 V to +10 V.
• High-resolution 12-bit signal conversion for precise control loop actuation.
• Pluggable connection technology (KS series design) allowing fast wiring swaps without disconnecting field cables.
• Complete galvanic isolation of 500 V between the internal K-bus and the field signal.
• Short-circuit proof output circuitry with a minimum load resistance of 5 kOhm.
• Diagnostic-friendly interface with optional control and status bytes alongside 16-bit output data in the process image.

Applications

• Proportional valve control and hydraulic actuator positioning.
• Speed reference setpoint transmission for variable frequency drives (VFDs).
• Analog calibration reference in plant engineering and machine manufacturing.
• Signal conversion in HVAC and building automation control cabinets.

Technical Specifications

Installation Guidelines

• Mount the terminal on a standard 35 mm DIN rail (conforming to EN 60715) with the locking mechanism engaged.
• Ensure that electrical power is entirely switched off before connecting or separating the pluggable wiring level.
• To wire the terminal, actuate the internal spring clamp by pressing a standard flat-blade screwdriver into the release slot.
• Maintain adequate ventilation clearance above and below the terminal block assembly to comply with the 0 to +55 degC operating envelope.
