Features
Installed where wiring enters or exits a building—or near controllers—the PROT485 helps maintain stable network communications. Protecting signal paths reduces the likelihood of network interruptions caused by electrical disturbances. This contributes to more consistent system operation across the site.
The board is designed for straightforward installation using standard EIA‑485 wiring and snap‑track mounting. Removable screw terminals simplify field connections, making it easier to add protection without reworking the network. This keeps upgrades efficient and minimally disruptive.
The PROT485 Lightning Protection Board safeguards BACnet MS/TP and EIA‑485 networks from electrical surges to help maintain reliable controller communication.
