Acquisition of high-density temperature data in space-restricted control cabinets is streamlined using the Beckhoff KS3228 Bus Terminal. This module interfaces directly with Pt1000 and Ni1000 RTD resistance sensors across 8 distinct channels, processing field temperatures with high operational efficiency. Designed with 1-wire connection technology, the hardware optimizes terminal density by utilizing a single signal wire per sensor, referencing a common return path. The integrated pluggable wiring level permits fast, tool-free terminal replacement during commissioning or maintenance cycles, leaving field wiring fully intact and reducing machine downtime.

The KS3228 is the direct pluggable equivalent of the standard KL3228 Bus Terminal. While the KL3228 utilizes permanent tension-clamp connections, the KS3228 features a detachable wiring block. They share identical register mappings, K-bus footprints, and electrical parameters, enabling a direct functional swap in existing K-bus configurations without software or PLC modifications.
Because this module utilizes a 1-wire connection scheme, it does not compensate for the resistance of the lead wires. Designers must keep lead wire runs as short as possible to prevent offset errors; every extra ohm of cable resistance will register as an apparent increase in temperature. When using long cable distances, software offsets must be calibrated inside the controller register configuration to offset systemic wire resistance. If high precision is required over long physical distances, consider switching to 2-wire or 4-wire RTD modules such as the KL3208 series.
To ensure stable RTD measurement signals, route sensor lines in shielded cables separated from high-voltage, high-frequency motor cables and AC power distributions. Connect the cable shield to a low-impedance ground bus bar immediately at the enclosure entrance point. When configuring the module, use the KS2000 configuration software or register-based PLC commands to choose between Pt1000 and Ni1000 scaling algorithms and to toggle active process data filter settings.
Mount the existing K-bus bus coupler or terminal block securely to a grounded 35 mm DIN rail (conforming to EN 60715).
Slide the KS3228 terminal onto the rail next to the existing unit, aligning the double slot-and-key locking mechanism until it clicks into place.
For wiring, insert a standard screwdriver into the spring actuation slot on the pluggable level, feed the stripped wire (9 to 10 mm stripping length) into the connection point, and release the tension clamp.
