Sierra instruments 900 series power supply & readout
SIERRA CONTROLLERMODEL#901M-AL-LOW/LOWUNITS 5LPM 0-1 RANGE OUTPUT 0-5VDCGAS PH3110V-60HZ
Sierra Instruments 900 Series Electronics include single-channel, dual-channel and five-channel power and readout systems, as well as auxiliary totalizers. Designed for use with Sierra s Series 600 and Series 800 mass flow meters and controllers, these electronic systems include the power supply ( 15 VDC), set point control, LCD display of flow rate in engineering units, and optional totalizers and alarms.
All 900 Series systems require 100/110/230 VAC input power and deliver a 0 5 VDC or 4 20 mA output signal for each transducer. Each channel on the single and dualchannel electronics system is individually scaled to display flow rate in engineering units on a 3.5 digit LCD readout.
The five-channel Flo-Box utilizes a 16-character LCD readout to display the channel and the flow rate in engineering units. Flo-Box also offers totalization, alarms and ratio control in a single, compact package. Tote-Box provides totalization for either the Flo-Box or Dual-Channel Electronics. This module totalizes and displays the mass flow. It has one to five resettable counters. Power is supplied by the the Flo-Box or Dual-Channel electronics.
