Allen‑Bradley 1762‑L24BXB MicroLogix 1200 PLC – Compact Automation Controller
Product Summary
The 1762‑L24BXB is a compact, powerful MicroLogix 1200 PLC engineered for micro‑to‑small automation applications. With fourteen digital inputs and ten outputs, including high‑speed FET channels, it handles counting, totalizing, and position monitoring with ease. A built‑in 24VDC power supply and mini‑DIN serial port support DF1, DH‑485, ASCII, and MODBUS protocols. This controller delivers reliable control in demanding industrial environments.
Product Procurement & Buyer Guide
When selecting a PLC for small‑scale automation, the 1762‑L24BXB offers an unmatched balance of I/O density and flexibility. It provides ten standard 24VDC inputs plus four fast inputs for high‑speed counting up to 20 kHz. The output side includes five relay contacts rated for 24‑125VDC and 120‑240VAC, four 24VDC FET outputs, and one high‑speed FET output. This combination suits both general‑purpose switching and precise motion control.
The embedded power supply operates on 24VDC and delivers 400 mA at 5VDC and 350 mA at 24VDC. With power usage of only 27 watts and heat dissipation of 17 watts, it keeps energy costs low. The inrush current at 24VDC is 15 A for 20 ms, ensuring stable startup.
Procurement managers value the compact dimensions: height 90 mm (104 mm with DIN latch open), width 160 mm, depth 87 mm. The controller mounts on DIN rail or directly to a panel. It weighs just 2.4 pounds, simplifying logistics. Ambient operating temperature ranges from 0 to 55 °C, with storage from -40 to 85 °C at 5‑95% relative humidity. This ruggedness guarantees longevity in harsh plant floors.
For communication, the 8‑pin mini‑DIN port supports DF1, DH‑485, ASCII, and MODBUS. This allows seamless integration with SCADA, HMI, and other controllers. The input circuit accepts 24VDC sink or source, and the output circuit uses relay or FET types. These features make the 1762‑L24BXB a versatile choice for OEMs and system integrators.
Expert Technical Evaluation & Performance Review
From an engineering perspective, the 1762‑L24BXB excels in applications requiring precise high‑speed counting. The four fast inputs and one high‑speed FET output operate at frequencies up to 20 kHz. This enables accurate totalizing and position monitoring without external encoder modules.
The relay outputs offer mechanical durability of 20 million cycles, with a minimum load current of 10 mA and common current per group of 7.5 A. FET outputs provide solid‑state switching for inductive loads. The controller’s power supply inrush current (15 A for 20 ms at 24VDC) demands careful upstream protection.
Installing the device inside an industrial enclosure reduces electrical interference. Keep it away from load lines, relays, and motor drives to maintain signal integrity. The controller uses no sensor power output, so external sensors require separate supply.
Overall, this PLC delivers reliable performance for packaging, material handling, and simple machine control. Its compact form factor and rich I/O set lower the total cost of ownership while boosting productivity.
