3. Well-featured and compact design

If you are thinking of improving the application of your equipment, SR provides

very many features. SR is very compact.

4. With the function blocks used for programming, the program storage capacity of SR is

large.

The control functions of SR can be implemented only with function blocks

incorporated into a function block diagram. The same level of control implemented by a

conventional PLC would require a much larger and more detailed program. When several

function blocks are linked together in a specific way, then relatively complicated control

functions can be implemented. SR has a storage capacity of programs for up to 128 function

blocks. There is a large application resource to satisfy the requirements for complicated

control. A program, when downloaded into SR will never be lost, as SR does not rely on a

battery for the memory function.

5. External Extendable Input/output

SR series machine can be connected with the relative SR-20E Extension Module.

Thus it can be extension to 20 points input/output once (12 points input and 8 points output).

One set of SR series machine can be externally connected with 5 extension modules. Thus 22

points machine can be extension to 120 points input/output (74 points input and 48 points

output). And it gives you a large storage capacity of your control.

Note:

One SR main machine can be connected with 5 extension modules at most. Two extension

modules are recommended to connect with one SR main machine. Otherwise the speed of the

running will be slow.

6. Real time clock function (Only main machines with RTC have this function.)

SR series intelligent controller has the real time clock recording function. It can

run and time according to the random time of your desiring and the accuracy can reach

second, which make your control of time be correct and accurate. And you can set 127

periods of different time. It is suitable for the system that needs the time control.

7. Analog input and transmission (The IA ports of DC type main machines have the analog

input function.)

In addition to receiving a switching input, SR can also receive the analog input to

implement the control of temperature, humidity, pressure, flow, level unit, etc., and transmit

them remotely to a computer for monitoring.
