Valve Outputs

The Sample Sequencer 6 switches sample streams to an analyzer using the valve outputs on the board. These outputs
provide 12 or 24 VDC to control solenoid valves. Sentry Equipment offers a manifold switching valve for use with the
Sample Sequencer 6. With additional hardware, other solenoid valve operating voltages may be used.

Maintenance

Cleaning

The Sample Sequencer 6 is constructed of rugged materials that do not require cleaning. If cleaning the external
surfaces is desired, a soft cloth and water is recommended.
