Operating on the internal K-bus communication backplane, the KS3042 samples analog process variables from field devices and transfers digitized values with 500 V electrical isolation to the fieldbus coupler or industrial controller.\u003c\/p\u003e\n\u003cp\u003eEquipped with a pluggable wiring assembly, the KS3042 enables fast maintenance and field replacement. The removable connector block allows the terminal housing to be swapped on the DIN rail without disconnecting individual signal wires, minimizing wiring errors and downtime. Field transducers can be powered directly from the module via the integrated 24 V DC power contacts, supporting compact 2-wire and 3-wire sensor wiring in control enclosures.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo single-ended analog input channels configured for 0 to 20 mA measurement
