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.

FAQ

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.
