product description :

3805H is a  Analog Output Modules

The analog output module is to drive the hardware output and related data path, select the current set value according to the operation mode, and also reverse and provide the result to the hardware output or software output as required. Modules can be set to CAS_IN and RCAS_IN automatic mode. SP outputs the set value after selecting the CASIN, SPLOCAL(local setting) and RCASIN and the feedback value by the SPSELECTOR.

In order to avoid drastic changes in the set value SP, a rate limiter would be set up to limit the rate of SP, and then SP would be restricted in absolute value by a clamper, and then a characterization compensator would be made according to special functions. After the characteristic compensation, SP and the bias value are added into three ways: the first way returns the SP selector; The second path enters the reverse path output parameter selector; The third way converts the engineering unit to a percentage in the converter, the scale parameter is PVSCALE(SP%), it can also output the reverse (INVERT SPAN 100 VALUE) setting value (INV.SP%) through the switch (INCCLOSE), and is output to the converter (block) by the transmission. SP supports a series (stage) structure. In CAS mode, the output of other modules must be used as the SP of the A0 module. The SP has standard speed and absolute value limits.
