Allen-Bradley 1762-L40BXB 40-Point Programmable Logic Controller

The Allen Bradley 1762-L40BXB is used to control and automate small-to-medium machinery and industrial processes. Think of it as the "brain" of a machine, reading signals from sensors, processing logic, and turning on equipment like motors and valves.

Specs:

• Total I/O Count: 40 embedded channels (24 inputs and 16 outputs)
• Inputs: 20 standard 24V DC digital inputs and 4 fast 24V DC inputs (supporting high-speed counter applications)
• Outputs: 8 relay outputs, 7 standard 24V DC FET outputs, and 1 fast 24V DC FET output tailored for Pulse Train Output (PTO) or Pulse Width Modulation (PWM)
• Memory Capacity: 6 KB total memory, splitting into a 4K-word maximum program area and a 2K-word data area
• Physical Connectivity: Features an 8-pin mini-DIN RS-232C serial communication port
• Expansion Limits: Capable of expanding up to 6 local 1762 expansion I/O modules
• DF1 & DH-485: For Allen-Bradley network communications and HMI connectivity
• Modbus RTU: For wide-ranging compatibility with third-party automation equipment
• ASCII: For communicating with serial printers, barcode scanners, and terminal devices
• Network Expansion: Optional external interface modules (such as the 1762-ENET) can be added to grant EtherNet/IP capabilities
• Analog Simulation: Includes integrated trimmer potentiometers on the housing for simulating or manually adjusting internal data registers
• Data Protection: Features 100% data retention. It can be backed up using an optional 1762-MM1 memory module or paired with a 1762-RTC real-time clock for scheduled automation tasks
• Form Factor: Compact design weighing approximately 510 grams (1.1 lbs) with dimensions measuring 90 mm high and 87 mm deep. It features a standard IP20 enclosure rating and supports standard DIN-rail or rugged panel mounting
• Maintenance: Built with the MicroLogix 1200 Removable Terminal Block (RTB) setup (catalog number 1762-RPLRTB40), allowing easy wiring replacements without disconnecting field signals
