Upon system power-off, the circuit switches to a high-impedance state of 100 k-ohms or higher, preventing current loop disruption.\u003c\/p\u003e\n\u003cp\u003eQ: Can the adapter power 2-wire field transmitters directly without external line modules?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The adapter provides a transmitter power supply of at least 15.0 V DC (at 20 mA) up to a maximum of 24.0 V DC. It also features a hardware current limitation of 40 mA or lower to protect against loop short-circuits.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBaseplate Alignment and Seating:\u003c\/strong\u003e Mount the unit firmly into its allocated slot on the A2BN3D baseplate.
