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.

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.

#Analog Output Modules #Beckhoff Bus Terminal

What is the primary difference between the Beckhoff KL4031 and KS4031?

The KS4031 model features a pluggable wiring level block, allowing the terminal insert to be easily swapped for maintenance without disconnecting the field wiring. The KL4031 model has fixed, non-removable terminal blocks.

What are the output voltage range and signal resolution of the KS4031?

The KS4031 provides a single analog output channel with a signal range of -10 V to +10 V at a conversion resolution of 12 bits.

Does the KS4031 require an external auxiliary power connection?

No, the KS4031 is powered directly through the internal K-bus and does not utilize power contacts.

Is the analog output isolated from the control network?

Yes, the KS4031 features 500 V galvanic electrical isolation between the internal K-bus logic and the field-side analog output circuit.
