Frequently Asked Questions (Expert & Buying Guide)
- Q1: Can this module drive inductive loads directly?
Yes, but we recommend external suppression (diode or RC snubber) for inductive loads to protect relay contacts, especially with DC coils. - Q2: What is the maximum switching frequency?
For relay outputs, keep switching below 10 Hz to ensure long contact life. For high-speed applications, consider transistor outputs. - Q3: How do I connect the common terminals?
There are two commons: COM0 (outputs 0-7) and COM1 (outputs 8-15). Each supports up to 8A total. - Q4: Is this module compatible with Twido Extreme?
Yes, TWDDRA16RT works with Twido Compact and Extreme base units. Check your base model for expansion capacity. - Q5: What is the best replacement for this module?
The direct replacement is TWDDRA16RT. For newer systems, consider Modicon TM3 series with adapter.
