Plug. Wire. Replace. — Removable terminals make installation and maintenance effortless.
You have spent hours in cramped control panels, struggling to rewire a failed I/O module. Every wire has to be removed, labeled, and then painstakingly reconnected to the new module. One mistake. One mislabeled wire. Hours of troubleshooting.
There is a better way. N Series I/O boards feature removable, pluggable terminals. Wire the terminal once. If a board ever needs replacement — pop off the terminals, swap the board, plug the terminals back in. No rewiring. No relabeling. No mistakes. Minutes instead of hours.
Every N Series I/O board comes with spring‑cage terminals that detach from the board. Wire the terminals on your bench or in the panel. When a board needs replacement — whether failed, upgraded, or reconfigured — simply pull off the terminals, remove the board, snap in the new board, and reattach the terminals. Zero rewiring. Zero downtime for rework.
This alone saves hours per replacement. Multiply by dozens of boards across your facility, and the savings are enormous.
No screwdrivers needed for wiring. Insert the wire, close the spring — done. Solid or stranded wire, 0.3 to 2.5 mm² (AWG 22‑14). Fast, secure, and vibration‑resistant. Perfect for factory floor conditions.
N Series covers every industrial I/O type you will ever need. Mix and match up to 32 modules per BL210/BL211/BL212/BL214 coupler.
Built for the factory floor. Electrical isolation (2KVrms), wide temperature operation (0°C to 55°C or wider per module), and robust EMC protection. N Series boards survive where low‑cost alternatives fail.
| Traditional Fixed‑Terminal I/O | N Series with Removable Terminals |
|---|---|
| Replace module → remove every wire → label each wire → reconnect wires to new module → test → pray no mistakes | Replace module → remove terminals (wires stay attached) → swap board → reattach terminals → done |
| Typical downtime: 30–60 minutes per replacement | Typical downtime: 2–5 minutes per replacement |
| High risk of wiring errors (misplaced wires, incorrect polarity) | Zero risk — wires never leave their terminals |
| Panel maintenance requires an electrician or trained technician | Any maintenance staff can swap a board — terminals are pre‑wired |
You are tired of spending hours rewiring failed I/O modules in tight panels. N Series removable terminals turn a one‑hour repair into a five‑minute swap. Your team will thank you.
You build panels that will be maintained by others. N Series boards make your panels easier to service. Your customers will appreciate the lower maintenance costs. You will get fewer after‑hours emergency calls.
