The internal resistance of the TK-IAH161 channel combined with cable run resistance must not exceed the transmitter's maximum load capability at 24 VDC. For self-powered (4-wire) transmitters, ensure appropriate isolators or common-ground references are applied to prevent ground loops that disrupt HART digital frequency-shift keying (FSK) signals.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eFor robust HART communication, the loop must have a minimum impedance of 250 ohms. If the field device cannot sustain a stable digital handshake, confirm that no external surge protection devices with high capacitance are installed in parallel with the loop, as they can shunt the high-frequency HART carrier signal.
