Honeywell 2MLQ-TR2A 16-Channel Transistor Output Module for Industrial Automation

Introduction

As industrial automation evolves, the demand for reliable and precise digital output modules grows. The Honeywell 2MLQ-TR2A meets this need with a 16-channel transistor output design, offering sink type operation for efficient control in modern manufacturing environments.

Technical Specifications Breakdown

The Honeywell 2MLQ-TR2A provides 16 output points with photo coupler isolation, ensuring signal integrity and protection. It operates at a rated load voltage of DC12/24V with a load voltage range of DC 10.2 ~ 26.4V. Each point supports a maximum load current of 0.5A, while the common (1COM) can handle up to 4A. The off leakage current is 0.1mA or less, and the maximum inrush current is 4A for 10 ms or less. Voltage drop on state is DC 0.3V or less. Response times are configurable via CPU parameter, ranging from 1ms to 100ms, with a default of 3ms for both off-to-on and on-to-off transitions. The module includes a surge absorber using a Zener diode compliant with IEC 61006-6-2, and two 4A fuses (non-replaceable) with a fuse cap rating of 50A. Fuse disconnection is indicated via LED and CPU signal, though not detected when external power is off. Current consumption is 70mA when all points are on, and external power supply voltage is DC12/24V ± 10% with ripple voltage 4 Vp-p or less. External connection uses an 18-point terminal block connector. Weight is 0.11 kg, and hot swap support is included.

Industry Applications

In discrete manufacturing, the 2MLQ-TR2A controls actuators, solenoids, and indicator lights with high reliability. Its 16-point common method simplifies wiring in panel layouts. For material handling systems, the module's fast response times (as low as 1ms) enable precise timing for conveyor sorting and robotic pick-and-place operations. The sink type output suits modern PLC systems that use sinking logic, reducing compatibility issues.

Installation & Setup Guidance

Mount the 2MLQ-TR2A securely in a DIN rail or panel, ensuring adequate ventilation. Connect the 18-point terminal block following the wiring diagram for sink type outputs. Verify external power supply voltage is within DC12/24V ± 10% and ripple is below 4 Vp-p. Configure response times via the CPU parameter to match application needs. The hot swap feature allows module replacement without powering down the system, minimizing downtime.

Maintenance & Reliability

Regularly inspect the module for LED indicators showing output status and fuse condition. The non-replaceable fuses protect against overcurrent; if a fuse blows, the LED and CPU signal alert the operator. Keep the environment within specified voltage and current limits to extend service life. The photo coupler isolation enhances noise immunity, reducing false triggers.

Compatibility & Integration

The Honeywell 2MLQ-TR2A integrates seamlessly with Honeywell PLC systems and other controllers supporting sink type digital outputs. Its 16-point common method and 18-point terminal block simplify wiring in existing cabinets. The module supports hot swap, enabling live replacement in critical systems. Verify compatibility with your controller's output module specifications before installation.

Selection Guide & Purchasing Advice

When selecting the 2MLQ-TR2A, confirm your system requires a 16-channel sink type transistor output module with DC12/24V operation. Ensure the load current per point does not exceed 0.5A and total common current stays below 4A.
