1200 & 1300 Data Sheet

Profile:

The 1200 and 1300 are microprocessor based temperature controllers offering superior flexibility and performance than our competitors versions. Packaged in an industry standard 1/8DIN format (48x96mm - 1200) and 1/8DIN (96x96mm - 1300) the units are manufactured using the latest SMT technology. The basic package offers an easy to configure, cost effective solution to many control situation but should the user require greater sophistication then options are available to deal with almost every requirement.

The units front facia has a Lexan membrane ensuring IP65 ingress protection as standard. In addition it has 4 keys for entering the options required by the user, two 4 digit LED displays showing set point and process temperature. In addition the unit has 4 red LED's indicating the status of each of the four possible outputs along with another 3 which can be programmed to meet the customer requirements.

The main input for the process variable is universal and can accept many types of sensor as standard such as all standard thermocouple types, resistance thermometers, thermistors, linear inputs and the are all selected via the face plate. There is no need for different models selected for different input type. One model does it all! In addition to the main input the unit can also be specified with a second auxiliary analogue input for use with a current transformer. You can also specify an isolated digital input which can select one of the two preset setpoints, select Manual-Automatic mode, reset the alarms memory, or enable the hold function.

The instrument can be specified with up to 4 outputs either relay (3A, 250V) or logic (12Vdc, 20mA). The stock model has one of each which can be configured as you so wish. An analogue output in voltage or current is also available. The function of each output is freely configurable from the faceplate keys. In addition to control and alarm outputs, you can have outputs that repeat the state of the digital or retransmission input by process variable, setpoint, drift, alarm limits and values acquired from serial line. Another isolated output (at 10 or 24Vdc, 30mA max.) is available to power external transmitters. The serial communication option (available in RS485 standard) allows connection to supervision systems and PLCs with two protocols: GEFRAN CENCAL and MODBUS RTU.

Instrument programming is facilitated by grouping parameters in functional blocks (CFG for control parameters, Inp for inputs, Out for outputs, etc.). The instrument can also select display parameters based on hardware configuration, automatically masking irrelevant parameters. The instrument is supplied with an "EASY" configuration with just a few parameters (only those for the model ordered and essential for controller operation). In this way, you just have to set the setpoint and alarm, and launch selftuning from the button. The 600 does all the rest. A PC programming kit is available for even simpler configuration, composed of a cable and a guided program for Windows environment (see data sheet code 80020).
