The module variant is an enclosed IP65\/panel-mount unit requiring a 24 VDC supply, whereas the cable variant is a passive, multi-conductor shielded wiring harness. Refer to your system-specific Bill of Materials (BOM) to verify the physical form factor.\u003c\/p\u003e\n\u003cp\u003eQ: What is the fail-safe behavior of the module variant if Modbus RTU communication is lost?\u003c\/p\u003e\n\u003cp\u003eA: Upon a communication timeout, the module executes its pre-configured fail-safe state, driving analog outputs to low-scale (typically less than 4 mA) or freezing the last valid value depending on jumper or software configuration settings.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding:\u003c\/strong\u003e For the cable variant, terminate the braided shield at the designated cabinet grounding bar only.
