The built-in battery maintains clock operation during power interruptions, with battery status monitoring available through the RTC:0\/BL status file.\u003c\/p\u003e\n\u003cp\u003eThe module supports removal and insertion under power, allowing maintenance procedures within compatible MicroLogix 1500 configurations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the battery in the 1764-RTC replaceable?\u003cbr\u003eA: No. The RTC module uses a built-in non-replaceable battery.\u003c\/p\u003e\n\u003cp\u003eQ: What is the supported clock accuracy of the 1764-RTC module?\u003cbr\u003eA: The RTC accuracy varies by operating temperature, ranging from +34 to -70 seconds\/month at 0 deg C to -133 to -237 seconds\/month at 55 deg C.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 1764-RTC be removed while the system is powered?\u003cbr\u003eA: The specifications indicate that removal and insertion under power are supported.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the 1764-RTC module into the designated MicroLogix 1500 accessory module interface with correct mechanical alignment. Verify that the module connector is fully seated before controller operation.\u003c\/p\u003e\n\u003cp\u003eMaintain temperature conditions within the specified operating range to preserve RTC timing performance and battery service life. Avoid prolonged exposure to elevated storage temperatures when the controller system is not operating.\u003c\/p\u003e\n\u003cp\u003eUse proper static discharge control procedures during installation and removal. Keep the module away from high-voltage wiring and maintain standard industrial cabinet grounding practices.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43656701804634,"sku":"1764-RTC","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1764-RTC2.jpg?v=1784016134","url":"https:\/\/www.plcmasters.com\/products\/1764-rtc-allen-bradley-real-time-clock-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
