The MC-6400 controller is a 64-channel gas monitoring controller that can communicate with up to 64 gas sensors or transmitters through an RS-485 Modbus communication. Four relays can be individually set up to the full scale gas reading and may be latching or non-latching. Used in conjunction with RKI’s transmitters to create a safer working environment.
The MC-6400 controller represents the latest leading edge technology in fixed gas detection today.
