Frequently Asked Questions (FAQ)

• What does the "undefined zone" between 0.4V and 4.5V mean?

The module cannot guarantee a definite on or off state in this voltage range. You must design your system to avoid this undefined region during normal operation.

• What typical devices can I control with this TTL module?

It ideally controls digital displays, logic circuits, opto-isolators, and other low-power 5V DC devices that require TTL-compatible signaling.

• Why is there a minimum load current requirement?

The module needs a small current flow (0.15 mA) to reliably detect the output state and ensure proper transistor operation in the circuit.

• Can I use this module in high-vibration industrial environments?

While robust, the open design requires additional protection in harsh environments. Consider enclosures for areas with significant vibration or contamination.

• What happens if I exceed the 24 mA per point rating?

Exceeding the current rating may damage the output transistors. Always ensure your connected loads operate within the specified 24 mA maximum limit. © 2025 Ubest Automation Limited. All rights reserved. Original Source: https://www.ubestplc.com/ Contact: sales@ubestplc.com Phone: +86 180 3000 5825
