Description

The BECKHOFF KS3182 is a high-accuracy, 2-channel analog input Bus Terminal designed for the precise measurement of differential voltage signals in the range of -2 V to +2 V. Operating within the K-bus system, this module digitizes analog process signals with a high resolution of 16 bits, ensuring reliable performance in demanding industrial measurement tasks. The terminal features a pluggable wiring design that simplifies maintenance and wiring assembly compared to standard terminal housings.

Equipped with galvanic isolation between the input channels and the K-bus, the BECKHOFF KS3182 protects sensitive control electronics from field-side voltage anomalies. Configurable parameters, such as conversion times and internal software filters, allow engineers to tailor the terminal behavior to specific system dynamics and signal conditions.

Features

Two differential analog input channels for high-accuracy voltage measurement.
16-bit analog-to-digital resolution for precise signal processing.
Pluggable connection technology (KS-series terminal housing) for fast, tool-free wiring exchange.
Integrated galvanic isolation of 500 V between the K-bus and the input signals.
Configurable 50 Hz filter and adjustable conversion time of 140 ms.
Direct integration into the Beckhoff K-bus system with status diagnostics.

Applications

Precise voltage monitoring and differential signal processing in industrial automation.
Connection of differential output sensors within control cabinets.
De-centralized data acquisition systems utilizing the Beckhoff K-bus architecture.
General test stand configurations and process engineering environments.

Installation Guidelines

Ensure the system controller and all power supplies connected to the K-bus and field wiring are completely de-energized before beginning installation.
Mount the Bus Terminal onto a standard 35 mm DIN rail conforming to EN 60715, ensuring the lock mechanism clicks securely.
Insert field signal wires into the pluggable terminal block using a compatible screwdriver to actuate the spring-clamp contacts. Verify wire stripping lengths are between 9 and 10 mm.
Connect the shield connections directly to a suitable ground potential to minimize electromagnetic interference on the analog signal inputs.
Apply power to the system and verify diagnostic LED activity to ensure normal communication with the bus coupler or master controller.

FAQ

What is the primary difference between the Beckhoff KS3182 and KL3182 Bus Terminals?

The BECKHOFF KS3182 features a pluggable wiring level that allows the entire wiring block to be disconnected from the main housing, whereas the KL3182 uses standard non-pluggable terminals, simplifying unit replacement and installation in high-uptime systems.

What signal type and voltage range does the BECKHOFF KS3182 support?

The BECKHOFF KS3182 is designed to measure differential analog voltage signals in a range from -2 V to +2 V with an outstanding measuring error of less than ±0.05% relative to the full scale value.

Does the BECKHOFF KS3182 require an external 24 V feed for its internal electronics?

No, the BECKHOFF KS3182 draws all required operating power directly from the internal K-bus (typically 85 mA), meaning it does not consume current from the power contacts of adjacent terminals.

What is the default conversion time and filtering configuration for the KS3182?

The BECKHOFF KS3182 features a default conversion time of 140 ms and an integrated 50 Hz filter, both of which can be configured via software to optimize for speed or noise rejection.
