INTRODUCTION:
The Sigma Myriad QLC (Monitor/Controller) is a 4-channel microprocessor based, state of the art,
process/level monitor/controller offering unmatched performance and full user configurability.
The QLC is used with primary measuring devices, whose input signal is compatible with common analog
outputs 4/20MA, 0-5VDC, 1-5VDC, and 0-10VDC.
Process indication for each channel is displayed in both numeric and graphic format on the QLC’s graphic
LCD display along with the current status of the unit’s 4 relay outputs.
All aspects of the instrument are user configurable through the ‘plain English’ menus and combinations of
the 5 user data key push buttons.
Available in 2 styles of mounting, ¼ DIN (4” x 4” nominal) and wall mounted Nema 4X enclosures, the
Myriad QLC is suitable for installation in all industrial environments.
