PID Controllers
The PID Controllers 5150
MX series is a series of state of art P.I.D. controllers having No. of advance
features. The controllers have features like fuzzy logic, Auto tuning, number
of output types, dual display for simultaneous display of parameter and set point,
Microprocessor based circuitry, Keyboard programmability, selection of type
of inputs, Relay outputs for alarms, RS485 / RS232 serial communication port,
DIN standard enclosure etc.
Feature
- Output type (Time proportional relay, 4 to 20 mA, 0 to 10V DC)
- DIN standard enclosure /
19" Rack modular construction
- User friendly
- Two alarm relays with multifunction programmability
- Reliable
- Separate displays for set point and process value
- Softstart and soak
- Input type selection
- RS485 / RS232 serial transmission port (Thermocouples, RTD, Strain gauges
etc.)
- 4-20 mA re-transmission signal output
- Switch mode power supply, wide power supply range
Technical Specification
- Working Voltage: 90 to 220 V AC, 1Æ, 50Hz
- Sensor Input: All types of T/C, RTD, PT 100, mV or mA, Bridge
sensors like strain gauge, load cells etc. In-built cold junction compensation.
Control parameters.
All parameters are keyboard programmable.
- Set point adjustable 0 to 100% of SPAN
- Proportional Band: 0 to 100% of span. If set to 0% the controller is ON/OFF
controller.
- Integral Time (Reset): 0 to 3600 Sec.
- Rate (Derivative): 0 to 1000 Sec.
- Dead Band (ON/OFF control hysteresis): 0 to 20% span.
- Inhibit reset: The integral action is suspended outside proportional band.
- Time proportional action: Can be set up to 99 Seconds.
- Soft Start: 0 to 60 unit / minute.
Control parameters.
All parameters are keyboard programmable.
- Setpoint adjustable 0 to 100% of SPAN
- Proportional Band: 0 to 100% of span. If set to 0% the controller is ON/OFF
controller.
- Integral Time (Reset): 0 to 3600 Sec.
- Rate (Derivative): 0 to 1000 Sec.
- Dead Band (ON/OFF control hysteresis): 0 to 20% span.
- Inhibit reset: The integral action is suspended outside proportional band.
- Time proportional action: Can be set up to 99 Seconds.
- Soft Start: 0 to 60 unit / minute.
Display:
4 digit 7 segment 0.5" for process value pV and 4 digit 7 segment 0.5" display
for set value sV for model 5150 MD. 7 segment 0.3" display for set point and
process value for 5150M. LED display for Alarms and outputs. Scaling of the
display and resolution is user programmable.
Controlling Output: 3 options are available which should be specified by the user. 1.
Relay: 3A, 240V AC max for resistive load. 2. 4 to 20mA max. load 12V with
built in power supply. 3. 0 to 10V.
Alarms:
Two alarms points can be set from 0 to 100% of the span with 0 to 20% hysteresis.
The alarm output can be: 1. Relay: 1 C/O 240V AC, 3A max. 2. Level: 5V DC
logic signal.
Soak:
One alarm output can be programmed as soak timer from 0 to 3600 minutes. The
corresponding relay can be energised
during soak period.
Re transmission: 4 to 20mA or serial communication RS485 / RS232 is available. The
scaling is as per the user programme.
Serial Communication: 2 wire multidrop, half duplex, asynchronous polled, 9600 baud rate,
Max. No. of Controllers on single loop 31, RS 485 protocol. The computer requires
RS 485 port or RS232C / RS485 converter. Driver software is available at extra
cost. The driver software is DOS/WINDOWS based.
