Frequently Asked Questions

• Q: What is this module typically used for?
• A: It is used to monitor the state of devices powered by 120V AC, such as manual switches, door sensors, or pump run-status contacts in industrial control panels.
• Q: Can it handle voltage spikes or noise on the line?
• A: Yes. The wide operating range (85-132V AC) and high isolation (1780V AC) provide good tolerance for typical line variations and noise.
• Q: How are the sixteen channels wired and grouped?
• A: The inputs are divided into two electrically isolated groups of eight. This allows separate power sources for different sections of your machine, improving safety and noise immunity.
• Q: Do the LEDs show if the input is powered or just if the PLC sees it?
• A> The LEDs are wired to indicate the actual voltage state at the input terminal, giving you a direct visual confirmation of the field device's status.
• Q: Is this compatible with 110V AC systems?
• A> Yes. The operating range starts at 85V AC, making it fully compatible with standard 110-120V AC control circuits commonly used in North America.
