The device operates as a 2-wire loop-powered transmitter, sourcing current proportional to RMS vibration velocity. It requires no field calibration or zero adjustment. Signal linearity is maintained across the 12-30 VDC excitation range, allowing direct interface to analog input cards without external signal conditioners.\u003c\/p\u003e\n\u003ch3\u003eTechnical Inquiries\u003c\/h3\u003e\n\u003cp\u003eQ: Does this transmitter support HART protocol?\u003c\/p\u003e\n\u003cp\u003eA: No. The 177230 outputs a standard 4-20 mA analog signal only. It does not support digital communication protocols.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum loop cable length?\u003c\/p\u003e\n\u003cp\u003eA: Maximum cable length is determined by the power supply voltage and loop resistance. Ensure compliance with Ohm's law to maintain at least 12 VDC at the transmitter terminals under load.\u003c\/p\u003e\n\u003cp\u003eQ: Can it be mounted on a magnetic base?\u003c\/p\u003e\n\u003cp\u003eA: Yes. However, roll the magnetic base onto the surface. Avoid \"snapping\" it into place, as the resulting mechanical shock can generate voltage spikes that damage the internal circuitry.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the transmitter directly to a clean, flat machine surface using the integral stud. Apply a torque of 20 N·m (177 lbf·in). If using a magnetic base, ensure proper seating without impact loading. Use shielded twisted-pair cable for the 4-20 mA loop. Connect the shield drain wire to the PLC\/DCS ground terminal only. Verify the loop power supply provides sufficient voltage headroom for the selected cable length.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e177230-02-01-05 Seismic Transmitter\u003c\/li\u003e\n\u003cli\u003e4-20 mA loop-powered configuration\u003c\/li\u003e\n\u003cli\u003eMultiple agency approvals included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDispatch \u0026amp; Packaging\u003c\/h3\u003e\n\u003cp\u003eDispatch occurs within 3-5 days after payment clearance via DHL \/ FEDEX \/ UPS.
