Designed to mount into standard Modicon 800 series housings, this compact module combines 16-bit logic processing with built-in system power, providing a cost-effective automation solution for mid-range industrial control applications. \u003c\/p\u003e\n\u003cp\u003eThe module executes user programs created with the Modicon 984 instruction set at a nominal processing speed of 5 ms per 1, 000 logic nodes. Integrated RAM provides 6K words for user logic and 1, 920 registers for state storage, yielding a total memory capacity of 8K words. Memory retention during line power interruptions is sustained by a 3 V lithium backup battery with a one-year service life, supported by a front-panel LED indicator that provides a 14-day advance warning before memory loss occurs.\u003c\/p\u003e\n\u003cp\u003eA dual-input power supply section allows primary line operation at 115 VAC or 230 VAC (selectable via a slide switch) alongside a dedicated 24 VDC backup or direct primary input. Operating status and diagnostic results are presented via front-panel status LEDs (PWR OK, READY, RUN, and BAT LOW). Physical security is maintained via a key switch on the front panel, which locks out unauthorized access to program logic. \u003c\/p\u003e\n\u003ch3\u003eFunctional Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003ePC-0984-380\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric \/ Modicon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eProgrammable Logic Controller CPU \u0026amp; Power Supply Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Series\u003c\/td\u003e\n\u003ctd\u003eModicon 984 Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProcessor Architecture\u003c\/td\u003e\n\u003ctd\u003e16-bit CPU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogic Execution Speed\u003c\/td\u003e\n\u003ctd\u003e5 ms \/ 1,000 nodes (nominal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Memory\u003c\/td\u003e\n\u003ctd\u003e8K words (6K logic + 1,920 state registers)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Options\u003c\/td\u003e\n\u003ctd\u003e115 VAC \/ 230 VAC (switchable), 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory Backup\u003c\/td\u003e\n\u003ctd\u003e3 V lithium battery (1-year life, 14-day low-batt hold-up)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProgram Protection\u003c\/td\u003e\n\u003ctd\u003eKey-operated memory protect switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible I\/O Hardware\u003c\/td\u003e\n\u003ctd\u003eModicon 800 Series housings and modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e5.34 lbs (approx. 2.42 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDiagnostics and Power Configuration\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003ePC-0984-380 \u003c\/strong\u003eincorporates standard Modicon status indicators to assist maintenance personnel during startup and troubleshooting:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePWR OK (Green): \u003c\/strong\u003eIndicates primary input voltage and internal DC outputs are within tolerance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eREADY (Amber): \u003c\/strong\u003eLit when the controller successfully passes internal power-up self-diagnostics. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRUN (Green): \u003c\/strong\u003eSignals that the CPU is executing user logic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBAT LOW (Red):\u003c\/strong\u003e Illuminates when the lithium battery voltage drops below the threshold, providing a 14-day window for battery replacement before user RAM data is degraded. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eInput power wiring accepts standard line AC or 24 VDC auxiliary power.
