3. Integral Time (Reset) : 0 to 3600 Sec.
4. Rate (Derivative) : 0 to 1000 Sec.
5. Dead Band (ON/OFF control hysteresis) : 0 to 20% span.
6. Inhibit reset : The integral action is suspended outside proportional band.
7. Time proportional action : Can be set up to 99 Seconds.
8. Soft Start : 0 to 60 unit / minute.

d. 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.

e. Controlling Ouput : 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.

f. 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.

g. Soak : One alarm output can be programmed as soak timer from 0 to 3600 minutes. The corresponding relay can be energised during soak period.

h. Re transmission : 4 to 20mA or serial communication RS485 / RS232 is available. The scaling is as per the user programme.

i. 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 convertor. Driver software is available at extra cost. The driver software is DOS/WINDOWS based.
