Frequently Asked Questions

What happens if the load impedance is outside the specified range?
Exceeding the specified load limits (300 Ohm for current; 2000 Ohm for voltage) will compromise signal accuracy and potentially damage the output stage.

Can I use this module for high-speed pulse width modulation?
No, this is an analog output module designed for steady-state signals, not high-speed digital switching.

How do I troubleshoot an output failure?
First, verify the 24V DC supply voltage. Next, ensure the analog signal wires are properly shielded and check for open circuits in the loop.

Selection Guide

• Identify your control signal requirements (voltage versus current).
• Ensure your controller model supports the Twido expansion bus.
• Calculate the total loop resistance to verify compatibility with the module's driving capability.
• Always confirm your PLC firmware version is compatible with the latest expansion module configurations.
