Sensor Inputs : The Model 18i has eight input channels whereas the Model 14i has four and the Model 12i has two. The instruments are identical in every other way. Each input is independent and is capable of supporting the same wide range of sensor types. Inputs are not scanned or multiplexed.
Silicon and GaAlAs diode sensors are supported over their full temperature range by using 10uA constant-current DC excitation.
Robust support for Negative-Temperature-Coefficient (NTC) resistor sensors by is given by using constant-voltage AC excitation. Example sensors include Ruthenium-oxide, Carbon-Glass, Cernox™, Carbon-Ceramic, Germanium and several others.
Positive Temperature Coefficient (PTC) resistor sensors including Platinum, CLTS and Rhodium-Iron RTDs use constant-current, AC or DC excitation.
The Model 18i / 14i / 12i includes built-in sensor calibration curves that support most industry standard temperature sensors. Additionally, eight user calibration curves are available for custom or calibrated sensors. Each user curve may have up to 200 entries.
Easy to use: The monitor's front panel consists of a large, bright TFT-LCD display, a 4-key keypad, an audio alarm and three status LEDs.
Several display formats may be selected. Up to eight temperature readings may be displayed simultaneously or two channels with input names and temperature shown in a large easy to read font. Additional screens include temperature readings along with relay and alarm status information.
A single key press takes the screen to a menu tree where most features and functions of the instrument can be configured.
Input Power : The monitor may be powered by any source providing 7.5 to 48 Volts AC or DC. The IEEE 802.3af Power over Ethernet (PoE) specification is also supported, allowing the Model 18i / 14i / 12i to be powered by it's local area network connection.
Alarms and Relays:Two 10A dry-contact relay outputs can be asserted based on temperature setpoints from user selected input channels.
Remote Control: The remote control interface is Ethernet. Remote interface commande language is IEEE-488.2 SCPI compliant.
LabView™ drivers are available for all remote interfaces.
Security: The Model 18i / 14i / 12i provides industrial grade security.
A built-in user configurable firewall protects the instrument from any unauthorized transactions.
HTTP Digest access authentication protects the built-in web server. HTTPS provides authenticated, encrypted communication.
Modbus: Modbus/TCP is an open industrial automation protocol that allows the Model 18i / 14i / 12i to interface directly to most Programmable Logic Controllers using the TCP interface.
Data logging: Data Logging is performed by continuously recording temperature and status to an internal 2-Gigabyte memory buffer. Data is time stamped so that the actual time of an event can be determined. Non-volatile memory is used so that data will survive a power failure.
Web 2.0 Server: Using secure Ethernet HTTPS protocol, the monitor’s embedded web server provides complete instrument control and configuration without the need for external platform-dependent software.
