Operating on an line AC supply of 85–264 VAC, this unit combines 10 discrete 24 VDC inputs with 6 electromagnetic relay outputs in a single integrated housing. It provides a compact footprint and reliable ladder logic processing for small-scale industrial automation applications.\u003c\/p\u003e\n\u003ch3\u003eIntegrated I\/O and Power System\u003c\/h3\u003e\n\u003cp\u003eThe controller includes 10 embedded 24 VDC digital inputs that accept both sinking and sourcing wiring configurations, including high-speed counter functionality on select channels. Output switching is handled by 6 relay channels capable of driving both AC and DC loads across isolated circuit groups. Powered by an line AC supply (120\/240 VAC nominal, 47–63 Hz), the controller also provides an auxiliary 24 VDC output (up to 200 mA) to power external sensors directly from the controller terminals.\u003c\/p\u003e\n\u003ch3\u003eMemory Architecture and Retention\u003c\/h3\u003e\n\u003cp\u003eProgram instructions and data registers reside in 1 K EEPROM non-volatile memory. This architecture retains approximately 737 instruction words and 437 data words permanently without relying on a battery backup. Retentive data and bit registers remain fully intact across long-term power outages, ensuring reliable operational recovery upon restoration.\u003c\/p\u003e\n\u003ch3\u003eSerial Interface and Network Integration\u003c\/h3\u003e\n\u003cp\u003eAn integrated RS-232 mini-DIN port supports the Allen-Bradley DF1 protocol for direct, point-to-point communication. Using standard programming cables (such as 1761-CBL-PM02), the controller connects to PC software, operator terminals, or hand-held programmers. For multi-drop industrial communication, the serial port can be linked to a DH-485 network using an external 1761-NET-AIC Advanced Interface Converter.\u003c\/p\u003e\n\u003ch3\u003eTechnical Parameters\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\u003e1761-L16BWA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eMicroLogix 1000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal I\/O Count\u003c\/td\u003e\n\u003ctd\u003e16 points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Inputs\u003c\/td\u003e\n\u003ctd\u003e10x 24 VDC (Sinking \/ Sourcing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Outputs\u003c\/td\u003e\n\u003ctd\u003e6x Relay Contacts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Power Supply\u003c\/td\u003e\n\u003ctd\u003e85–264 VAC (120\/240 VAC nominal, 47–63 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuxiliary Sensor Power\u003c\/td\u003e\n\u003ctd\u003e24 VDC (200 mA max)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e29 VA @ 120 VAC; 36 VA @ 240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInrush Current\u003c\/td\u003e\n\u003ctd\u003e30 A for 8 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory Type\u003c\/td\u003e\n\u003ctd\u003e1 K EEPROM (737 instruction words \/ 437 data words)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Port\u003c\/td\u003e\n\u003ctd\u003eBuilt-in RS-232 (DF1 \/ DH-485 via AIC+)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003e1500 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.31 lbs (0.60 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What power supply voltage is required to operate the 1761-L16BWA controller?
