This isolation prevents common-mode high-voltage transients on the primary utility line from coupling onto the 24 VDC backplane bus. The internal power conditioning circuitry mitigates channel-to-channel noise cross-talk and provides output voltage stabilization within a +\/- 5% regulation window, preserving signal integrity across analog input cards and cold junction compensation (CJC) circuits operating on the local subsystem rack.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum allowable hold-up time during an AC power loss event?\u003c\/p\u003e\n\u003cp\u003eA: The module maintains rated output voltage for a minimum of 20 ms following a complete AC input interruption at full nominal load.\u003c\/p\u003e\n\u003cp\u003eQ: How is chassis grounding properly established on the primary terminal block?\u003c\/p\u003e\n\u003cp\u003eA: The primary AC wiring connection requires a direct, low-impedance connection from the line ground lead to the module FG (Frame Ground) terminal to meet the 1500 VAC isolation safety standard.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the module vertically into the designated power supply slot of the DCS base rack, ensuring top and bottom chassis locking mechanisms are fully engaged.\u003c\/li\u003e\n\u003cli\u003eVerify that line power is de-energized before connecting the 100-240 VAC wiring to the terminal strip.\u003c\/li\u003e\n\u003cli\u003eTerminate the protective earth conductor directly to the FG terminal using a ring lug and torque to the manufacturer standard.\u003c\/li\u003e\n\u003cli\u003eAllow a minimum of 50 mm clearance above and below the module heat sink fins to maintain passive convective airflow.\u003c\/li\u003e\n\u003cli\u003eApply AC power and verify that the green READY LED illuminates, indicating valid 24 VDC bus output generation.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":52742529876248,"sku":"PW702-S1","price":200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/PW702_1200x1200_ce60a789-a2e3-44c6-a8da-01cac75fc341.jpg?v=1790041588","url":"https:\/\/www.innoplcsync.com\/products\/yokogawa-pw702-s1-power-supply-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
