Technical Specification
| Parameters | Description |
|---|---|
| No. of Inputs | 4, 6 or 8 channels |
| Input types | K type thermocouple or RTD(PT-100) |
| Range | For K type t/c 0 to 1372 °C and For Pt-100 0.0 to 400.0 oC |
| Resolution | 0.1 °C or 1 °C for RTD inputs and 1°C for thermocouple inputs. |
| Accuracy | Better than ± 0.1% of the specified range. |
| Display | 2 digit 0.5" Red 7-segment LED display for Zone no. |
| 4 digit 0.5" Red 7-segment LED display for process value | |
| 4 digit 0.5" Red 7-segment LED display for set value | |
| 6 digit 0.3" Red 7-segment LED display for real-time clock and calendar optionally provided only when computer interface is provided. | |
| Tuning | Manual tuning of PID values. |
| Control Action | PID or On/Off. |
| Cold Junction Compensation (CJC) | Built-in automatic from 0 - 50 °C for thermocouple input. |
| Faulty Sensor Indication | Display shows FLt-1 for reverse input and FLt-2 for open input. Under fault conditions, all the control outputs and relays will be turned OFF. |
| Parameter Settings | Using front panel membrane keyboard to set the PID, set points and time values. |
| No. Of Profiles | Single Program for each zone. |
| Ramp Soak Steps | 1 to 16 Steps per program. (Common OR Independent for all the zones). |
| Time per Step | 1 to 540 mins. (9 Hr. per step). Two or more steps can be combined for longer time duration. |
| Program Hold Facility | Manual Hold or Auto Hold (Hold back feature for guaranteed Ramp/Soak facility). |
| Control mode | User can select the single set point control mode and Ramp/Soak control mode through front panel keyboard. |
| Copying Facility | This facility allows Copying of Ramp/Soak profiles parameters of the 1st zone to all remaining zones. |
| Memory Backup | Retention of PID and set values in the non-volatile memory in the event of power failure. On power resumption, the program will resume automatically from the last set point. |
| Alarm Output | 2 Extra Relay outputs configured as High and Low Alarms common for all zones (Relay changeover contacts rated for 5A @ 230VAC). |
| Control Outputs | 0 to 10VDC pulses to drive external SSRs or linear signal of (4-20)mA or (0-5)VDC with soft start and power limit facility. (Independent for each zone). |
| Digital Interface (Optional) | RS485 on Modbus ASCII protocol for PC interface with supporting Microsoft Window-based software. |
