1-8 | Model 5100 HD Analyzer
Controller Communications
All analyzer functions are controlled by microprocessors housed within the
electronics enclosure. These include:
•
(1) Non-isolated Analog Input (4 to 20 mA or 0-5 Volts)
• (1) Isolated discrete DC Input
• (1) Isolated 4-20 mA analog output per laser diode (i.e. one output for single
laser analyzer and (2) outputs for dual laser analyzer)
•
(4) Solenoid Valve Drives
•
(4) Relay Contacts
• (2) RTD Inputs
• Moisture Reference Cell
• Piezo-Resistive Transducer Input
• (3) Solid State Relay Drives (PWM)
• Single Isolated Discrete Input
• (3) Serial Ports: (1) RS-232, (2) RS-485
• 100 Mbs Ethernet Port
• MQX RTOS and Modbus capability
The Model 5100 HD is congured, and analyzer parameters are set, using either
the analyzer display and keypad, or the Web Interface. The 4-line x 20-character
VFD provides moisture data, system operating parameters, system messages, and
alarm conditions. The 20-button keypad on the front of the unit is used to set or
change operating parameters and system values. There is a serial interface inside
the main electronics enclosure, which is intended for service use only.
