Analog Output Module (D/A Converter)
The 12-bit analog output module converts digital data of 0 through 4000 to 2 channels of analog signals. The analog output
module is a functional module and the digital data for conversion must be stored to a link register, depending on the analog
channel and the mounting slot number of the analog output module in the system setup. The output mode can be selected
using the rotary switch to meet five different analog signal ranges; 0 to 10V, ±10V, 0 to 5V, ±5V, or 4 to 20 mA.
