Operating with a nominal input voltage of 220V AC (input range of 194–264V AC RMS), this module delivers a backplane output current of 8 Amperes at +5V DC to power critical system components.\u003c\/p\u003e\n\u003cp\u003eTo protect system integrity and prevent data corruption, the \u003cstrong\u003e1771-P6S\/B\u003c\/strong\u003e features an automated backplane shutdown mechanism. If the AC line voltage drops below the minimum operating threshold, the module immediately generates a shutdown signal in the backplane to ensure only valid data is retained in memory. The shutdown signal is automatically lifted once the line voltage recovers above the low-voltage limit. The module occupies a single slot, mounts directly onto the I\/O chassis side plate, and ships with a 5-position terminal block for field wiring.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProvides a regulated backplane output current of 8A at 5V DC.\u003c\/li\u003e\n\u003cli\u003eIncludes an automatic undervoltage shutdown signal to prevent data corruption during brownouts or power drops.\u003c\/li\u003e\n\u003cli\u003eSupports both remote and local sensing configurations via two hardware jumpers located near the gold-plated edge connectors.\u003c\/li\u003e\n\u003cli\u003eOffers scalable power expansion by allowing two power supplies to be paralleled on the same I\/O chassis using a 1771-CT cable.\u003c\/li\u003e\n\u003cli\u003eCompact 1-slot form factor designed for seamless integration on the 1771 I\/O chassis side plate.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDelivering stable backplane power to Allen-Bradley PLC-5 programmable controller architectures.\u003c\/li\u003e\n\u003cli\u003eEnvironments with fluctuating 220V AC power grids requiring hardware-level memory protection and managed system shutdowns.\u003c\/li\u003e\n\u003cli\u003eParalleled power supply configurations where current demands exceed the capacity of a single 8A supply module.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical 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\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Line\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePLC-5 \/ 1771 Control Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1771-P6S (Series B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUPC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e662468206075\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModule Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNominal Input Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e220 Volts AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Voltage Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e194–264 Volts AC RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrequency Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e47–63 Hertz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax Real Input Power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e56 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax Apparent Input Power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e89 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax Transformer Load\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e140 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBackplane Output Current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 Amperes at +5 Volts DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFuse Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.5 Amperes, 250 Volts, slow-blow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChassis Slot Allocation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 Slot (mounted on side plate)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eParallel Configuration Options\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCompatible with -P6S, -LWP, -LZP, and -LXP supplies\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInterconnection Cable\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1771-CT (for paralleled configurations)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.88 lbs (0.85 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation \u0026amp;
