1336-MOD-L3 Allen Bradley

Description

Product Name: 1336-MOD-L3   Allen Braley Input module

Product details:  

The Allen-Bradley 1336-MOD-L3 is a specialized communication or control interface module designed for use with the legacy 1336 series of Adjustable Frequency AC Drives (including the 1336 PLUS, PLUS II, FORCE, and IMPACT).

Specifically, the “L” series modules typically refer to Contact Closure Interface (TTL) or Control Interface boards that allow the drive to receive discrete input signals at specific voltage levels.

1. Product Description

The 1336-MOD-L3 is an optional, internal hardware modification for Allen-Bradley 1336 drives. Its primary function is to provide a standardized interface for Control Input Signals. By installing this module, the drive can be controlled via external switches, relays, or PLC outputs to perform functions like Start, Stop, Reverse, and Jog.

2. Technical Specifications

While specific nuances depend on the base drive it is installed in, the general parameters for the -L3 module are:

3. Key Advantages

• Seamless Integration: Designed by Rockwell Automation specifically for the 1336 family, ensuring 100% hardware compatibility.

• Enhanced Control: Allows the drive to interface with modern 24V DC control circuits, which are the industry standard for safety and reliability.

• Noise Immunity: Provides optical isolation, which prevents electrical noise from the control wiring from interfering with the drive’s microprocessor.

• Durability: Built to industrial standards to withstand high-vibration and high-temperature environments common in motor control centers (MCC).

4. Safety and Precautions

Warning: Dealing with Variable Frequency Drives (VFDs) involves high voltage risks.

• Power Down: Always ensure the drive is powered off and the DC Bus capacitors have fully discharged (check the “Bus Charged” light) before installing or removing the module.

• Static Protection: Use an ESD (Electrostatic Discharge) wrist strap when handling the board to avoid damaging the CMOS components.

• Wiring Accuracy: Ensure the 24V DC polarity is correct. Incorrect wiring can damage the interface board or the drive’s main control board.

• Firmware Check: Ensure the drive’s firmware version supports the L3 module functionality.

5. Product Applications

The 1336-MOD-L3 is used in systems where the drive needs to be integrated into a hardwired automation loop:

• Conveyor Systems: For remote Start/Stop and Emergency Stop control via 24V sensors.

• Pumping and HVAC: Interfacing with pressure switches or thermostats that output 24V signals.

• Machine Tooling: Allowing a CNC controller or PLC to command speed directions and jog functions.

• Legacy System Maintenance: Replacing failed interface boards in existing 1336 drive installations to extend the machine’s lifecycle.
