This link includes three kinds of modules: each with basic and enhanced , please take the time to explain
1: 0-20mA 24V output load resistance of not more than 910 Euro
2: 0-5V output , 0-10V output current is less than 7mA
3: Key subtraction output
1 Overview
Based onRS485 Interface ,Modbus Analog output protocol control module.
IsolationRS485Interface, supportModbus-RTU Agreement.
2: Wide operating voltage :DC8V-30VPower reverse does not work. Using original MC34063A 38V switching power supply can work within , the power consumption is less than0.5W.
Current output type:0-20mA (21mA MAX), The output voltage 12V, 24V.
Voltage output type :0-5V,0-10V, ( can be customized 0-21V)
OutputAccuracy : Standard12PositionDA, the error does not exceed 5 per thousand standard value .
Optional DisplayLED:4Position0.36Inch red , direct display output value
Dimensions:88 * 72 * 59
Working temperature :-35~+50.
Using standard35mmRail mounting .
Application: analog output control, automatic control .
Can be customized for a controlled waveform generator.
Enhanced : Optional belt1-6Switch inputs and emergency preset settings.The state of the digital inputs can be used "IOModule communication tool " read.The basic model no such function .
Key operation can type :INprefix = st1 1 IN2As the output of the key changes in the use of, IN3Rapid buttons.prefix = o
Pressed aloneIN1OrIN2, Decrease or increase the output value0.01 (mA,V); Has been pressed2Seconds will change continuously.
In caseIN3Press , then pressIN1OrIN2, Decrease or increase the output value1.00 (mA,V);
Output value increased up to the maximum output capacity is no longer increased.
Output value is reduced to0So far.
Key connection as follows :
Output through software correction , if you set the output value exceeds the maximum output capacity of the module , the maximum output value flashes .
