Powered by a 120\/240 VAC line voltage source, this controller integrates twenty I\/O points—comprising twelve 120 VAC discrete inputs, eight relay outputs, four analog inputs, and one analog output—making it well-suited for small-scale automation applications requiring both discrete logic and basic analog processing.\u003c\/p\u003e\n\u003ch3\u003eIntegrated I\/O and Processing Capacity\u003c\/h3\u003e\n\u003cp\u003eThe controller features twelve 120 VAC discrete input channels with an 8-millisecond nominal filter setting and eight heavy-duty relay outputs capable of handling 24 to 125 VDC or 0 to 240 VAC loads. Its internal 1K EEPROM memory supports approximately 737 instruction words and 437 data words, accommodating standard bit logic, timers, counters, and arithmetic instructions for machine control.\u003c\/p\u003e\n\u003ch3\u003eAnalog Capabilities and Measurement\u003c\/h3\u003e\n\u003cp\u003eBuilt-in analog features include four differential input channels supporting voltage ranges of -10.5 to +10.5 VDC and current ranges of -21 to +21 mA, alongside one configurable analog output. Data conversion is performed using a 16-bit signed integer format with a coding range of -32,768 to +32,767, allowing direct integration with process variables, sensors, and modulating final control elements.\u003c\/p\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\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1761-L20AWA-5A\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 Type\u003c\/td\u003e\n\u003ctd\u003eProgrammable Logic Controller (PLC)\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 Points\u003c\/td\u003e\n\u003ctd\u003e20 points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiscrete Inputs\u003c\/td\u003e\n\u003ctd\u003e12 points (120 VAC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiscrete Outputs\u003c\/td\u003e\n\u003ctd\u003e8 points (Relay)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Inputs\u003c\/td\u003e\n\u003ctd\u003e4 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Output\u003c\/td\u003e\n\u003ctd\u003e1 channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e120\/240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory Capacity\u003c\/td\u003e\n\u003ctd\u003e1K 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\u003eRS-232 (DF1 Protocol)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Weight\u003c\/td\u003e\n\u003ctd\u003e0.85 kg (1.88 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifecycle Status\u003c\/td\u003e\n\u003ctd\u003eDiscontinued \/ Obsolete\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eEnvironmental and Mounting Requirements\u003c\/h3\u003e\n\u003cp\u003eThe unit supports DIN rail or panel mounting in either horizontal or vertical orientations, noting an operating temperature range of 0 deg C to +55 deg C for horizontal mounting and 0 deg C to +40 deg C for vertical mounting.
