HONEYWELL 2MLQ-TR8B Product Description

Overview

HONEYWELL 2MLQ-TR8B is a MasterLogic ML200 series transistor output module for Honeywell MasterLogic-200 or ML200R PLC systems. The ML200 manual identifies 2MLQ-TR8B as a 64-point transistor output module, source output, with 0.1 A per point. Public distributor records also list the full catalogue variant 2MLQ-TR8B-CC; the supplied model 2MLQ-TR8B should match that ML200 digital output family.

Features

The module provides 64 transistor output channels, source type, with photocoupler isolation. Rated load voltage is DC 12 / 24 V, load voltage range DC 10.2 to 26.4 V. Maximum load current is 0.1 A per point and 2 A per common. Common method groups 32 points per 1 COM.

Off leakage current is 0.1 mA or less. Maximum inrush current is 4 A for 10 ms or less. Maximum on-state voltage drop is DC 0.3 V or less. Response time is 1 ms or less for ON to OFF and OFF to ON at rated resistive load. A Zener diode surge absorber is included, referenced to IEC 61006-6-2 in the distributor record.

External power supply is DC 12 / 24 V ±10 percent, with ripple voltage 4 V p-p or less. Power supply current is 10 mA or less when connected to DC 24 V. Module current consumption listed by Honeywell ML200 manual is 230 mA when all points are ON. Operation indicator LEDs light when an input or output point is ON; distributor record notes 32-point LED operation by switch operation. External connection uses two 40-pin connectors, suitable cable size 0.3 mm², and module weight 0.15 kg.

Principle

The PLC CPU writes output states to the 2MLQ-TR8B module. Each source transistor channel switches the external DC 24 V field load from the module output to the load; the load return or common wiring follows the source-output PLC convention. Photocoupler isolation separates PLC internal logic from field wiring. LEDs indicate channel status for commissioning, troubleshooting and maintenance.

Replacement should verify the ML200 main CPU or rack compatibility, module slot, I/O address assignment, source versus sink output, external DC supply voltage and polarity, common grouping, load current per point and per COM, inductive or resistive load, connector pinout, cable size, surge suppression, PLC program mapping and any redundant system configuration. Do not mix source and sink modules in the same output circuit unless the PLC manual and wiring design explicitly support it.

Applications

HONEYWELL 2MLQ-TR8B is used in existing Honeywell MasterLogic-200 or ML200R PLC control panels for machine automation, conveyor control, packaging equipment, process skids, pump or valve control, material handling, production lines, utility control cabinets and general industrial digital output switching. In legacy installations, it serves as a direct replacement transistor output module spare when the ML200 rack, source-output configuration, connector, power supply and I/O mapping match the original unit.
