The ADAM-5024 is a 4-channel analog output module. It receives the digital input from the ADAM-5000 system or the host computer on RS-485 network. The format of the data is engineering units. It then uses the D/A converter controlled by the system module to convert the digital data into output signals. You can specify slew rates and start up currents through the configuration software. The analog output can also be configured as current or voltage through the software utility. The module protects your equipment from ground loops and power surges by providing optical isolation of the D/A output and transformer based isolation up to 500 VDC.
