The controller integrates 14 digital 24 VDC inputs (10 standard inputs and 4 fast inputs) and 10 relay outputs powered by an internal 120\/240 VAC line voltage supply. It processes incoming field signals across differential input impedances (3.3 kohm for fast inputs 0-3, 2.7 kohm for standard inputs 4-13) to drive physical load executions through individual mechanical relay contacts.\u003c\/p\u003e\n\u003ch3\u003eHardware 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\u003e1762-L24BWA\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\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.50 lbs (0.68 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e3.50 in x 4.33 in x 3.43 in (8.9 cm x 11.0 cm x 8.7 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C (32 to 131 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e120\/240 VAC Line Voltage (50\/60 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Capacity\u003c\/td\u003e\n\u003ctd\u003e14 Channels (10 Standard 24 VDC, 4 Fast 24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Capacity\u003c\/td\u003e\n\u003ctd\u003e10 Channels (Relay Outputs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e3.3 kohm (Inputs 0-3), 2.7 kohm (Inputs 4 and above)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOn-State Input Voltage\u003c\/td\u003e\n\u003ctd\u003e14 to 26.4 VDC @ 55 deg C (Inputs 0-3); 10 to 26.4 VDC (Inputs 4+)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOff-State Limits\u003c\/td\u003e\n\u003ctd\u003eVoltage: 0 to 5 VDC; Max Leakage Current: 1.5 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication \u0026amp; Deterministic Processing\u003c\/h3\u003e\n\u003cp\u003eThe Allen-Bradley 1762-L24BWA manages backplane bus communication velocity across expanded 1762 I\/O module banks via an integrated high-speed expansion interconnect. Firmware flash compatibility ensures deterministic scan execution when interfacing with local digital and analog I\/O cards. High-density I\/O channel scaling allows local memory image tables to map inputs 0-3 as high-speed counters or latching inputs without degrading standard ladder logic processing speeds. Integrated status indicators provide visual diagnostic synchronization with logic state transitions across the controller front housing.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the electrical differences between inputs 0-3 and inputs 4-13 on the 1762-L24BWA?\u003c\/p\u003e\n\u003cp\u003eA: Inputs 0-3 feature a nominal impedance of 3.3 kohm and an on-state voltage threshold of 14 to 26.4 VDC (at 55 deg C) optimized for fast-response high-speed signals. Inputs 4 and above feature a 2.7 kohm impedance with a lower on-state voltage threshold of 10 to 26.4 VDC for standard industrial 24 VDC input devices.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 1762-L24BWA require an external 24 VDC power supply to energize its internal processor logic?\u003c\/p\u003e\n\u003cp\u003eA: No. The unit contains an internal AC-to-DC converter that operates directly from a 120\/240 VAC primary utility supply to power the processor logic, internal circuitry, and backplane expansion interface.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Isolation\u003c\/strong\u003e: Disconnect main 120\/240 VAC power sources before mounting, wiring, or attaching 1762 expansion modules to the controller to prevent electric shock or hardware damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting \u0026amp; Clearance\u003c\/strong\u003e: Secure the controller on a 35 mm DIN rail or surface-mount using screws.
