1.1 Description

TM
The PLATINUM Series Controller offers unparalleled flexibility in process measurement. While the
controller is extremely powerful and versatile, great care has gone into designing a product that is easy
to set up and use. Automatic hardware configuration recognition eliminates the need for jumpers. The
TM
PLATINUM Series Controller displays only the menu items associated with the system's custom
configuration.
Each unit allows the user to select the input type from 9 thermocouple types (J, K, T, E, R, S, B, C, and N),
Pt RTDs (100, 500, or 1000 Ω, with a 385, 392, or 3916 curve), thermistors (2250 Ω, 5K Ω, and 10K Ω), DC
voltage, or DC current. The analog voltage inputs may be single ended bipolar, differential absolute or
differential ratiometric, and both voltage, and current are fully scalable using a single point or 10-point
linearization to virtually all engineering units with a selectable decimal point that is perfect for use with
pressure, flow, or other process inputs.
Control is achieved using the PID, on/off, or heat/cool control strategy. PID control can be optimized
with an Autotune feature; and in addition, a fuzzy logic Adaptive Tuning Mode allows the PID algorithm
to be continuously optimized. The instrument offers up to 16 Ramp and Soak segments per Ramp and
Soak program (eight each), with auxiliary event actions available with each segment. Up to 99 Ramp and
Soak programs can be stored, and multiple Ramp and Soak programs can be chained, creating
unmatched ramp and soak programming capability. Multiple Alarms can be configured for above,
below, hi/lo, and band triggering using either absolute or deviation Alarm trigger points.
TM
The PLATINUM Series controller features a large, three-color, programmable display with the
capability to change color every time the Alarm is triggered. Various configurations of mechanical relay,
SSR, DC pulse, and isolated or non-isolated analog voltage or current outputs are available. Every unit
comes standard with USB communications for firmware updates, configuration management, and data
transfer. Optional Ethernet and RS-232 / RS-485 Serial communications are also available. The Analog
Output is fully scalable and may be configured as a proportional controller or retransmission to follow
your input signal. The universal power supply accepts 90–240 Vac. The low-voltage power option
accepts 24 Vac or 12–36 Vdc.
Additional features usually found only on more expensive controllers make these the most powerful
products in their class. Some additional standard features are remote Setpoint for cascaded control
setups, High-high/Low-low Alarm functionality, external latch reset, external Ramp and Soak program
initiation, combination Heat/Cool Control Mode, configuration save and transfer, and configuration
password protection.
