Made for closed-loop PID control, this 1/32 DIN controller handles thermocouple, RTD, thermistor, analog, and strain-gauge inputs and provides relay outputs. It is powered by an AC supply, presents readings on a single 4-digit display, and connects via USB. Works great for oven, furnace, and process temperature regulation.

The PLATINUM Series family of microprocessor-based PID controllers offer unparalleled flexibility in process measurement. While extremely powerful and versatile, great care has gone into designing a product that is very easy to set-up and use.
The automatic hardware configuration recognition eliminates the need for jumpers and allows the firmware to automatically simplify itself, eliminating all menu options that do not apply to a specific configuration. Offered in 1/32, 1/16, and 1/8 DIN sizes, the 1/16 and 1/8 DIN models can be configured with dual displays. Models are available with single and dual 4 digit displays or single 6 digit display.
The voltage or current inputs are bipolar and fully scalable to virtually all engineering units, with a selectable decimal point that is perfect for use with pressure, flow, or other process input.
Control can be achieved by using the on/off or PID heat/cool control strategy. PID control can be optimized with an auto-tune 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, with auxiliary event actions available with each segment. Up to 99 saved programs which can be chained to create up to 1584 discreet segments. Multiple alarms can be configured for above, below, hi/lo, and band triggering using either absolute or deviation alarm trigger points.
The PLATINUM Series device features a large, three-color, programmable display with the capability to change color and/or change the state of designated outputs every time an Alarm is triggered. Various configurations of mechanical relay, SSR, dc pulse, and analog voltage or current outputs are available. Up to 6 programmable outputs, including isolated and non-isolated, are best in class.
Every unit comes standard with USB communications for firmware updates, configuration management, and data transfer. The Analog Output is fully scalable and may be configured as a proportional controller or as retransmission to follow your display.
The remote setpoint feature of the PLATINUM Series Controllers can be used in a variety of applications where setpoints can be sent to the controllers from remote devices such as manual pots, transmitters, computers, etc. This feature can also be used to set-up a "cascade control" system, where the remote setpoint input is generated by another controller.
Cascade control schemes can provide tighter control of a process when you have two linked variables, one of which has a much slower (typically 4X or more) response than the other. The slower responding variable is used as the input to the primary or master controller, and the faster responding variable is used as the input to the secondary or slave controller. The output of the primary controller is scaled to be used as the setpoint for the secondary controller.
Additional features usually found only on more expensive controllers make this the most powerful product in its class.
Optional "embedded ethernet" on the 1/16 and 1/8 DIN models allow the units to connect directly to an Ethernet network and transmit data in standard TCP/IP packets, or serve Web pages over a LAN or the Internet. Optional serial communications are also available configurable as RS232 or RS485, with straightforward ASCII commands or MODBUS(R). All three types of communications interfaces (USB, Ethernet, and Serial) can be installed and active simultaneously.
