AS300 Series Module Manual 2.1 Overview This chapter describes the specifications for analog-to-digital modules, their operation, and their programming. In this chapter, “ module ” refers to the analog-to-digital modules AS04AD-A, AS08AD-B, and AS08AD-C. 2.1.1 Characteristics _2 (1) Select a module based on its practical application. AS04AD-A: Has four channels. A channel can receive either voltage or current input. AS08AD-B: Has eight channels. A channel can receive voltage input. AS08AD-C: Has eight channels. A channel can receive current input. (2) High-speed conversion Analog signals are converted to digital signals at a rate of 25 ms per channel. (3) High accuracy Conversion accuracy:
The error range for both voltage input and current input is ±0.2% at ambient temperature of 25° C. The number of voltage/current inputs that are averaged is 100. (4) Use the utility software to configure the module. The HWCONFIG utility software is built into ISPSoft. You can set modes and parameters directly in HWCONFIG without spending time writing programs to set registers to manage functions.
