The Allen-Bradley 1762-L24AWAR sinking and sourcing controller delivers robust automation for industrial applications. This MicroLogix 1200 unit provides a compact solution for machine control. It efficiently handles 14 AC inputs and 10 relay outputs at 120 Volts AC. The controller operates on an input power of 120-240V AC. Its mounting dimensions are just 3.5 x 4.33 x 3.43 inches.
Product Procurement & Buyer Guide
Procurement engineers value the 1762-L24AWAR for its clear spec alignment. This controller requires an input power range of 120 to 240 Volts AC. It features a specific on-state voltage range of 79 to 132 Volts AC. The off-state voltage range sits at 0 to 20 Volts AC. These metrics ensure compatibility with standard global power systems.
The product solves key pain points for system integration. Its 14 inputs operate at 120V AC, making them ideal for discrete sensors. The 10 relay outputs offer flexibility for switching high-current loads. The maximum inrush current reaches 250 mA at 120 Volts AC. This capability allows direct control of small motors and contactors.
Application engineers must consider its communication limitations. The RS-232 port only supports DH Full-Duplex protocol. It cannot initiate messages but can only respond to requests. You cannot alter its communication parameters. This constraint simplifies setup but limits network complexity.
Expert Technical Evaluation & Performance Review
The 1762-L24AWAR demonstrates strong signal integrity for AC systems. Its off-state leakage current stays at a maximum of 2.5 mA. This low leakage prevents false triggering of sensitive loads. The on-state current varies from 5 mA minimum to 16 mA maximum. The nominal current sits at 12 mA at 120 Volts AC.
The controller handles impressive DC current for auxiliary tasks. It can manage 400 mA at 5 Volts DC or 350 mA at 24 Volts DC. This feature supports powering small sensors or indicators directly. The operating frequency of 47 to 63 Hertz ensures stable performance across various grids.
Isolation performance is a critical strength for this unit. It provides five distinct working isolation voltages. These include input-to-backplane and output-to-backplane isolation. It also isolates input groups and output groups from each other. The power supply remains isolated from the backplane too. This robust isolation protects against electrical noise and surges.
