Honeywell Analytics 301C Three-Zone Digital Controller

Honeywell's Vulcain 301C continuously monitors and controls toxic gases, combustible gases, and oxygen hazards. It uses an addressable RS-485 Modbus communication protocol and daisy chain wiring so it only takes two pairs of wires to connect up to 96 transmitters on the three input channels.

The 301C controller offers unique zoning capabilities that permit the averaging and comparison of multiple sensor readings. Zoning can reduce operational costs by ensuring that localized brief fluctuations registered at a single transmitter do not accidentally activate relays.
