Expert FAQ & Purchasing Guide

• Can the MLE-TP32A handle inductive loads directly? While it supports 0.2A per point, we strongly recommend adding external flyback diodes when driving inductive loads to prevent semiconductor degradation.
• What is the maximum current for the entire module? The 32 points are grouped into a single common. Ensure the total simultaneous load current does not exceed the 2.0A COM limit.
• Does this module support AC loads? No, the MLE-TP32A is designed strictly for DC 12/24V open collector logic. Use relay modules for AC switching requirements.
• How do I diagnose a channel that stays "On" regardless of PLC state? This typically indicates a transistor failure due to overcurrent or a short circuit. Check load resistance before replacing the MLE-TP32A module.
• Selection Advice: When should I choose the MLE-TP32A over a relay module? Opt for the MLE-TP32A if your switching frequency exceeds 1Hz or if you require high-density I/O (32 points) in a single rack slot.
