Microprocessor Controller and Electronics
The M500e TOC Analyzer contains seven proprietary electronic board assemblies
which monitor and control Analyzer functions:
•
System board including a system on module CPU with ARM microprocessor, 4 GB
memory, 1 GB DDR RAM, non-volatile flash memory for operator settings, digital
input/output (I/O), display graphics controller, RS-232 (serial) port, interface-to-USB
memory devices, Ethernet port, and WiFi (optional).
•
Fan controller which controls three fans, one for thermal control, within the Analyzer
•
Passive interconnect board
•
Instrument controller I/O board with interfaces to pumps and motors, UV lamp,
external devices, via binary input, four alarms, and three 4-20 mA outputs
•
LED capacitive touch panel display and interface
•
Analog to digital conversion boards (2) with integrated signal conditioning circuits
for cell conductivity and temperature measurements
Data Outputs
The Sievers M500e TOC Analyzer offers three 4-20 mA outputs, four alarm outputs,
and two isolated binary (start/stop) inputs.The Analyzer also includes one serial
(RS
-
232), one USB, and one Ethernet output allowing flexibility for exporting and
printing data. Real-time and historical data can be transferred from the Analyzer via
Ethernet (using a communications software, such as Modbus or ProfiNet) or from the
serial port to a computer (using a communication software such as PuTTY. The
Analyzer also enables the use of a communications software (such as PuTTY) to
issue commands to the Analyzer via a serial (RS-232) or Ethernet connection. (For
more information, see
.)
NOTE:
The Analyzer’s USB port is designed for connection to a USB memory
device. The USB port does not support connectivity to a computer or printer.
