3-in-1 Digital Process Monitor
JC-13D2
The JC-13D2 Process Indicator is a microprocessor based indicator alarm that can be field configured for a wide variety of applications. The instrument provides a highly visible color touchscreen with easy to understand bar graph, scaled numeric display, and front panel alarm messages. Bar graph scaling, alarm setpoints, and time delays are all field selectable. Adjustments are made directly from the faceplate of the instrument by scrolling through a user friendly, English language menu. The unit is constructed of rugged polymer housing with a gasketed NEMA 12 faceplate. Up to three channels can be displayed at once, each with its own custom name and units, bargraph scaling, and alarms.

Versatile: Field selectable input types: 2 or 4 wire 4-20 mADC, 10k Thermistor, J or K Thermocouple, Potentiometer, 0-2.5 VDC, or Pulser. Thermistors and thermocouples are linearized and cold junction compensated. The Numeric display can be scaled to any desired display range from the front panel. The bar graph range and scaling can be set independently from the Input scaling. The 0-20/4-20mA re-transmission output can be scaled independently as well.
Alarm Sequences: The 2 alarms for each channel can be configured as HI-HI, HI, LO, or LOLO alarms with individually adjustable dead bands and Time Delays. Alarm adjustment is done in scaled engineering units, not percentages. The 2 relay outputs can be assigned to an individual alarm or as a common alarm output with alarm silencing logic. Each relay can be configured as auto reset or manual reset.

The JC-13D2 is a versatile display monitor with built-in alarm contacts. It accepts a variety of analog input types and provides a bargraph display and alarm contacts. It is ideal for boiler draft, drum level, tank levels, flow rates, operating pressures, temperatures, or any other common process monitoring applications.
Some three-channel application examples:
- Drum Level, Steam Flow, and Feedwater Flow
- Drum Pressure, Drum Temperature, Stack Temperature
- DA Tank Level, Condensate Tank Level, Make-up Water Flow
- Return Water Temperature, Supply Water Temperature, Loop Water Flow
- Main Oil Pressure, Oil Temperature, Oil Flow
