Product Overview

The Honeywell 2MLP-AC23 is a dedicated power module for the MasterLogic-200 series. It converts AC input into stable DC output for your PLC system. This 2MLP-AC23 unit accepts a wide input range from AC 170V to AC 264V. It delivers a clean DC 5V output at 8.5A maximum current. The module includes a built-in input fuse for safety. Users cannot replace this fuse internally. The 2MLP-AC23 also provides a RUN contact output. This contact signals the normal operation status to your controller.

Technical Specifications

The 2MLP-AC23 has a rated input voltage of AC 200V to AC 240V. Its total input voltage range spans from AC 170V to AC 264V. The input frequency operates at 50 or 60 Hz. The acceptable frequency range is 47 Hz to 63 Hz. Efficiency reaches 65% or more under normal load conditions. The built-in input fuse follows UL standards as a slow blow type. This 2MLP-AC23 allows instantaneous power interruptions up to 10 ms. The main output voltage is DC 5V with a tolerance of ±2%. Output current capacity is 8.5A continuous.

Overcurrent protection activates at 9.0A or higher. Overvoltage protection triggers between 5.5V and 6.5V. The 2MLP-AC23 includes a voltage indicator LED. This LED lights up when the output voltage is normal. The RUN contact provides a dry relay output at DC 24V, 0.5A. Minimum switching load for the RUN contact is DC 5V at 1mA.

RUN Contact Response Times

The RUN contact on the 2MLP-AC23 has specified response speeds. The OFF to ON response time is 10 ms or less. The ON to OFF response time is 12 ms or less. These fast response times ensure accurate status reporting. Your PLC can quickly detect any power anomalies. The mechanical life of the RUN contact exceeds 20 million operations. Electrical life reaches 100,000 or more cycles at rated current.

Wiring and Terminal Information

Use a cable size between 0.75 mm² and 2 mm² for connections. The 2MLP-AC23 requires compressed terminal lugs. Recommended terminal types are RAV 1.25 - 3.5 or RAV 2 - 3.5. Always tighten terminal screws to the specified torque. Loose connections cause voltage drops and overheating. Route AC power wires away from signal cables. This practice reduces electrical noise interference.

Installation Guide

Follow these steps to install the 2MLP-AC23 correctly.

• Step 1: Confirm the main power supply is completely turned off.

• Step 2: Locate the leftmost slot on the MasterLogic-200 rack.

• Step 3: Slide the 2MLP-AC23 into the dedicated power slot.

• Step 4: Push firmly until the backplane connector seats properly.

• Step 5: Secure the module with the top and bottom mounting screws.

• Step 6: Connect the AC input wires to the L and N terminals.

• Step 7: Connect the ground wire to the FG terminal.

• Step 8: Attach the RUN contact wires to the appropriate terminals.

• Step 9: Power on the system and verify the green LED lights up.

Do not attempt to open or repair the 2MLP-AC23 internally. The input fuse is non-user-replaceable. Contact Honeywell support for any internal failures.

Common FAQs

Q1: Can the Honeywell 2MLP-AC23 run on 110V AC input?
No, the 2MLP-AC23 requires a minimum of AC 170V input. It does not accept 110V AC power sources.

Q2: What does the RUN contact on the 2MLP-AC23 actually do?
The RUN contact closes when the output voltage is normal. Your PLC uses this 2MLP-AC23 signal for power status monitoring.

Q3: What happens if the output current exceeds 9.0A?
The overcurrent protection will activate immediately. The 2MLP-AC23 shuts down the output to prevent damage.

Q4: Why is the efficiency only 65% for this power module?
The 2MLP-AC23 uses linear regulator technology for clean DC output. Lower efficiency is normal for this design type.

Q5: How do I know if the built-in fuse has blown?
The 2MLP-AC23 will show no output voltage and no LED indication. The fuse cannot be replaced by the user.

Related Accessories

Use a 20-pin pre-wired cable for easy 2MLP-AC23 connections. Consider a surge protector for the AC input line. Add a backup power supply for critical systems. These accessories enhance the reliability of your 2MLP-AC23 installation. They also protect against line voltage spikes.
