FAQ – Frequently asked questions

Can I use this module with 12 V loads?
No. The output range is 20.4–28.8 V DC. Do not apply lower voltages.
Is it compatible with sinking inputs?
Yes, as a source output it drives sinking inputs (common negative).
What happens if I overload one channel?
Internal protection limits current. The module automatically recovers after fault removal.
Can I connect inductive loads directly?
Yes, up to 2000 mH. For larger coils, add an external freewheel diode.
How do I mount it?
Snap onto a 35 mm DIN rail; no screws needed.
Is the HE‑10 cable included?
No. You need a separate cable (e.g., 24‑wire ribbon with IDC connector).

Selection guide & practical tips

For high‑speed counting: prefer relay outputs? No – this transistor module handles 300 µs response, perfect for fast indexing.
Shared commons: two common points allow grouping loads (e.g., 8+8). Balance current to stay below 2 A per common.
Noise immunity: use twisted‑pair wires for long runs; the photocoupler insulation reduces ground loops.
Replacement: direct drop‑in for TWDDDO16TA (improved protection).
Spare stock: keep one module for emergency swaps – 0.07 kg saves shipping cost.
