Expert Review
“The TWDDRA16RT offers a balanced mix of channel density and relay robustness. With 16 outputs and 2A per channel,
it handles small motors, solenoids, and indicators well. The 7 ms response time suits most logic controls.
For maintenance, the removable terminal block and clear labeling reduce downtime. A solid choice for OEM panels.”

Lighting and signal towers – on/off switching with relay isolation - ▸
Test equipment and small machinery – relay actuation for safety interlocks
Frequently Asked Questions
Q: Can I use this module with a third-party PLC?
A: Yes, it works as a standard relay output card. Check voltage compatibility (5V/24V logic).
Q: What is the max switching frequency?
A: Relay outputs are rated for 10 Hz max. For high-speed, use transistor outputs.
Q: Does it support both AC and DC loads?
A: Yes, relay contacts are agnostic – up to 2A at 24VDC or 250VAC (resistive).
Q: How to choose between 16 relay vs 16 transistor?
A: Relays handle higher current and isolation. Transistors are faster and longer life for DC.
Q: Is there a LED for each output?
A: Yes, 16 green LEDs indicate ON/OFF status – helpful for troubleshooting.
Q: What spare parts should I keep?
A: Keep spare terminal blocks and a replacement module. Relays are not field-replaceable.
Selection Guide
- ▸
Choose TWDDRA16RT if you need 16 relay outputs with high isolation. - ▸
For mixed loads (AC/DC) and moderate speed, relays outperform solid-state. - ▸
Use with Twido base for seamless integration. Check common grouping (0-7 / 8-15). - ▸
If your application uses over 2A, consider interposing relays or contactors.
