The Allen-Bradley 1762-L40BWAR MicroLogix 1200 PLC delivers precise control for micro automation tasks. This compact controller features 20 standard and 4 fast 24VDC inputs plus 16 relay outputs. It operates on 120-240VAC and supports DF1, DH-485, ASCII, and MODBUS protocols.
Product Procurement & Buyer Guide
The 1762-L40BWAR simplifies procurement for engineers needing a scalable PLC. Its 24 inputs handle diverse sensors, while relay outputs drive actuators up to 10A. The controller's AC power supply reduces installation complexity.
For communication, the embedded 8-pin mini-DIN port supports DF1, DH-485, ASCII, and MODBUS protocols. This port allows seamless integration with HMIs, SCADA systems, and programming workstations. A separate programming port enables simultaneous online edits and test functions.
The controller meets stringent agency certifications including UL 508, C-UL under CSA C22.2 no. 142, and Class I, Div. 2. These approvals ensure safe operation in hazardous locations. Buyers can trust the 1762-L40BWAR for industrial reliability.
Expert Technical Evaluation & Performance Review
The 1762-L40BWAR uses a 24VDC sink/source input circuit with fast channels 0-3. These fast channels handle high-speed events like encoder pulses, while standard channels suit general-purpose sensing. Input circuit type offers flexibility for various sensor types.
Relay outputs provide 20 million mechanical cycles and support 24-125VDC or 120-240VAC loads. This durability makes them ideal for frequent switching applications. The controller dissipates 22W of heat, requiring adequate ventilation in the enclosure.
The power supply delivers 600mA at 5VDC and 500mA at 24VDC for internal logic and sensor power. Note: The sensor COM connects internally to chassis ground. Do not use the 24VDC sensor supply for output circuits. This design prevents ground loops and ensures proper operation.
Environmental tolerance spans 0 to 55°C operating and -40 to 85°C storage. The unit withstands inrush currents of 25A at 120VAC and 40A at 240VAC. These specs guarantee reliable startup even in demanding industrial conditions.
