The 3D3-GN portion of Honeywell's technologies is intended to provide an easy-to-use, cost-effective and self-contained method for monitoring and controlling industrial processes in hazardous and non-hazardous atmospheres. It is designed to provide complete control over a wide range of process parameters such as temperature, pressure, level and flow within hazardous atmospheres. Features of this system include CSA/UL/ATEX certification, an integrated safety panel, and an intuitive operator interface. Other features include a large display area with color-coded indicators, process and safety alarms with audible and/or visual indications, individual process alarms, and a variety of outputs including relays, switches, and analog signals. Additionally, the 3D3-GN system features an adjustable safety rating, RS485 communication, and diagnostic tools to check the system status.
