8864 Compact Data Controller

The hard-working 8864 Compact Data Controller
accurately and securely acquires, stores and
protects CEMS data in tight spaces.

The 8864 Compact Data Controller provides the 64-bit power you need in a small form factor, C1D2 compliant unit.

This device is ideal for tight spaces and hazardous environments.  It offers power and storage to meet specific site requirements and update Continuous Emissions Monitoring System (CEMS) shelters to the latest technology.

This unit provides the firmware functionality of the 8864 Data Controller in a compact design that is certified for operation in a Class 1, Division 2, or ATEX explosive environment. 

8864 Compact Data Controller

Collect, monitor, QA, and report on emissions data from continuous monitoring systems with confidence.

The 8864 Compact has dual Gigabit Ethernet interfaces, allowing it to communicate independently and simultaneously with an instrumentation or CEMS network and with the StackVision server.  Each network port can support multiple sessions of data polling and remote user interaction — all while the 8864 continues to collect, compute and store new data.

Eight digital inputs and eight digital outputs plus two serial ports provide additional I/O.  Two built-in USB ports allow connection to external keyboards or mice, as well as a convenient method to upgrade firmware.

A standard VGA port supports a monitor for access to the menu-driven interface during setup and initial configuration. A GUI Interface is available remotely via a network connection and web browser to perform common functions and interact with the 8864, but all functions, readouts, and settings are available through the character-based MDI. The MDI is accessible through remote terminal sessions with tools like PuTTY or by emulation in the StackVision client.
