2MLQ-RY1A | Honeywell Digital Output Module - Petro Auto Tech

Product Overview

The 2MLQ-RY1A is a digital output module from Honeywell, part of the MasterLogic-200 series. It provides 8 relay output points with a single common terminal, designed for reliable switching in industrial automation. This module supports resistive loads up to 2A at DC24V or AC220V, making it suitable for controlling actuators, indicators, and other field devices.

Technical Specifications Analysis

The 2MLQ-RY1A uses relay isolation for each output point, ensuring robust electrical separation. It handles a rated load voltage and current of DC24V 2A (resistive load) or AC220V 2A (COSφ=1). The minimum load is DC5V at 1mA, while the maximum load voltage reaches AC250V or DC125V. Off leakage current is only 0.1mA at AC220V, 60Hz. The maximum on/off frequency is 3600 times per hour. Current consumption is 260mA when all points are on. An LED indicator shows output on status. The module weighs 0.13 kg.

Application Scenarios & Usage Methods

This relay output module is ideal for controlling solenoid valves, contactors, and signal lamps in manufacturing lines. Use it to switch DC loads like small motors or AC loads like pilot lights. For best results, connect resistive loads within the rated 2A limit and avoid inductive loads without proper snubbers. The 8-point design allows compact wiring in panels, saving space.

Installation Guide & Packing List

Mount the module on a DIN rail inside an enclosure. Ensure proper grounding and use twisted-pair wiring for signal integrity. The packing list includes one 2MLQ-RY1A module and a user manual. No additional accessories are provided.

Purchasing Advice

When selecting output modules, match the voltage and current ratings to your load requirements. The 2MLQ-RY1A offers reliable relay switching for both DC and AC circuits. Petro Auto Tech provides genuine Honeywell parts with fast delivery. Verify compatibility with your MasterLogic-200 base unit before ordering.

Repair & Maintenance Tips

Inspect relay contacts periodically for wear or pitting. Keep the module clean and dry, and avoid exposure to dust or corrosive gases. Replace the module if the LED fails to light or if output switching becomes erratic. Store in a static-free environment.
