The internal signal processing pathways support transparent digital Frequency-Shift Keying (FSK) modulation overlays compliant with the 4-20 mA HART loop protocol. This enables bi-directional passthrough of field instrument diagnostics, device status, and configuration data without causing signal distortion on the primary current loop.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the channel-to-channel isolation in the DU-PWPR21 protect system loop integrity?\u003c\/p\u003e\n\u003cp\u003eA: Galvanic channel-to-channel isolation electrically decouples each output loop, preventing ground potential differences and stray field currents from cross-coupling between channels or feeding back into the system backplane.\u003c\/p\u003e\n\u003cp\u003eQ: Does the module interfere with HART digital communication signals when driving 4-20 mA current outputs?\u003c\/p\u003e\n\u003cp\u003eA: No, the onboard output circuitry maintains constant impedance across the HART FSK frequency band, enabling uninterrupted bi-directional HART communication alongside primary current signals.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure the I\/O rack or mounting chassis is de-energized or operating under authorized hot-swap conditions prior to module insertion.\u003c\/li\u003e\n\u003cli\u003eAlign the module housing with the backplane guide slots and push firmly until the retention latches fully click into place.\u003c\/li\u003e\n\u003cli\u003eTerminate signal wiring at the dedicated field termination assembly, maintaining separation between low-voltage signal lines and AC power cables.\u003c\/li\u003e\n\u003cli\u003eGround all shielded twisted-pair cable drain wires at a single cabinet earth point to minimize high-frequency noise coupling.\u003c\/li\u003e\n\u003cli\u003eConfirm that the total loop load resistance on each active current channel remains within the designated module driving limits.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53604839719221,"sku":"DU-PWPR21","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/CC-PDOB0151405043-176_Cocoai_0e7ec401-c10f-43ce-a8bb-4eb348b375cd.png?v=1789711688","url":"https:\/\/www.5gplc.com\/products\/honeywell-du-pwpr21-hart-analog-output-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
