Product Overview of the Honeywell MLE-TP32A Output Module

The Honeywell MLE-TP32A provides 32 digital output channels in a compact package. Each channel uses an open collector transistor output design. The rated input voltage is DC12/24V for flexible system integration. The load voltage range spans from DC10.2V to DC26.4V.

The maximum load current reaches 0.2A per individual output point. The common COM terminal handles up to 2A total across all channels. Off leakage current stays at 0.1 mA or less for reliable off state detection. The maximum voltage drop when on is DC 0.4A at rated load.

This Honeywell MLE-TP32A uses a common method of 32 points per COM. The internal current consumption is 120 mA for normal operation. An external power supply provides the load voltage separately. The module weight is only 100 grams for easy mounting.

Output Characteristics and Protection

The MLE-TP32A uses open collector outputs for sinking applications. Each output switches to ground when turned on. The load connects between the output and the positive supply voltage. This configuration works with most DC loads including relays and solenoids.

The maximum voltage drop of DC 0.4V keeps heat generation low. Off leakage current of 0.1 mA prevents false triggering of sensitive loads. The 10 MΩ insulation resistance ensures good isolation between circuits. The common method groups all 32 points to a single COM terminal.

The external power supply requires DC12/24V with 10 percent tolerance. The ripple voltage must stay at or below 4 Vp-p for stable operation. The external supply draws only 20 mA for the module itself. Load current comes from the same supply but depends on your field devices.

Response Time and Performance

The Honeywell MLE-TP32A provides consistent 1ms response times. Off to on transition takes 1 millisecond or less from command to output. On to off transition also takes 1 millisecond or less after turn off command. These ratings apply with rated resistive loads connected.

Fast response times support high frequency output applications. This includes pulse width modulation and rapid sequencing operations. The module can handle up to 500 output cycles per second theoretically. Always respect the maximum load current and duty cycle limits.

The internal current consumption of 120 mA comes from the system backplane. This does not include the load current from external devices. Plan your system power budget accordingly. The lightweight 100 gram design reduces stress on mounting rails.

Installation Guide for the MLE-TP32A

Follow these steps to install the Honeywell MLE-TP32A correctly.

1. Power down the entire control system before installation.

2. Insert the module into an available I/O slot on the rack.

3. Secure the module with the retaining clips or screws.

4. Connect the external DC power supply to the COM terminals.

5. Verify the supply voltage stays between DC10.2V and DC26.4V.

6. Connect each load between an output point and the positive supply.

7. Ensure total load per COM does not exceed 2 Amps.

8. Keep each output point load below 0.2 Amps maximum.

9. Use appropriate gauge wire for the load current levels.

10. Test each output channel individually before system operation.

Use twisted pair wiring for outputs longer than 10 meters. Install flyback diodes across inductive loads like relays and solenoids. This protects the output transistors from voltage spikes. Keep output wiring separate from low level signal cables.

Frequently Asked Questions (FAQ)

1. What type of loads can the MLE-TP32A drive?
The Honeywell MLE-TP32A drives resistive and inductive DC loads. Typical applications include relays, solenoids, indicator lamps, and small valves. Always add flyback diodes for inductive loads to prevent damage.

2. Does this module require an external power supply?
Yes, the MLE-TP32A needs an external DC12/24V power supply for loads. The external supply provides current to your field devices. The module draws its internal power from the system backplane separately.

3. Can I connect 24V AC loads to this output module?
No, the Honeywell MLE-TP32A works with DC loads only. The open collector design switches DC current to ground. AC loads require a different type of output module with relay or triac outputs.

4. What happens if I exceed 0.2A on a single output point?
Exceeding 0.2A per point may damage the output transistor permanently. The module has no built-in overcurrent protection per channel. Use an external fuse or limit the load current to safe levels.

5. How many output points can I turn on at the same time?
The MLE-TP32A allows all 32 outputs to be on simultaneously. However, the total current per COM terminal is limited to 2A. Calculate your total load current to stay within this 2A limit.
