Special module
model
Digital value converted from the
AH04AD-5A analog quantity of input
CH0~CH3 of AH04AD(Length=8)
2. Conversion between analog modules and digital modules that AHRTU-PFBS supports:
When the input / output mode of the analog module is positive voltage or positive current,
the corresponding digital value is 0 ~32000; for example, if the modes are 0V~10V and
4mA~20mA, the corresponding digital values are both 0~32000.
When the input /output mode of the analog module is negative voltage or negative
current, the corresponding digital value is -32000~32000; for example, the modes are
-10V~+10V, and -20mA~20mA, the corresponding digital values are both -32000~32000.
3. AHRTU-PFBS-5A must be installed to the CPU slot of the main rack; supports maximum
8 racks including 1 main rack and maximum 7 extension racks and 48 I/O modules.
