Description
The Neutronics MCA Multi-Channel Controllers are designed to accept up to 8 inputs. Primarily used with gas detector heads, the MCA controllers will also accept individual inputs from various types of monitoring instruments or transducers. A backlit LED display is provided to show the status of each channel, display graphs, and enable configuration of the unit (set alarm levels, program the output relay voting, etc.). The MCA can be programmed on-site by the user using the password protected configuration program. Each monitoring channel provides relay contact outputs along with 4-20mA and voltage outputs.
Data logging of each channel is provided as standard. For applications where intrinsically safe gas detector heads are installed in a potentially explosive atmosphere, a safety barrier must be fitted to each individual channel to limit the maximum voltage and current under a fault condition (short circuit) and prevent an incendive spark.
