AS Series Module Manual 3.1 Overview An analog output module receives four 12-bit blocks of digital data from a CPU module. The module converts the digital data into analog signals (voltage or current). 3.1.1 Characteristics (1) Select a module based on its practical application. AS04DA-A: Has four channels. A channel can send either voltage or current output. (2) High-speed conversion _3 Digital signals are converted to analog signals at a rate of 2 ms per channel. (3) High accuracy Conversion accuracy: The error range for both voltage output and current output is ±0.2% at ambient temperature of 25° C. (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. 3.2 Specifications and Functions 3.2.1 Specifications Electrical specifications 3-2 Module Name AS04DA-A Number of Outputs 4 Analog-to-Digital Voltage input/Current input Conversion Supply Voltage 24 VDC (20.4 VDC–28.8 VDC) (-15% to +20%) Connector Type Removable terminal block Conversion Time 2 ms/channel An analog circuit is isolated from a digital circuit by a digital integrated circuit/ optocoupler, but the analog channels are not isolated from one another.
Isolation between a digital circuit and a ground: 500 VDC Isolation between an analog circuit and a ground: 500 VDC Isolation between an analog circuit and a digital circuit: 500 VDC Isolation between the 24 VDC and a ground: 500 VDC Isolation Weight 145 g
