· Product Introduction
SPV Analog Output Module is precision-engineered based on a new generation of embedded systems. The module features an isolated communication interface, allowing it to communicate independently with PCs, PLCs, touchscreen panels, and other terminal devices. Additionally, the module is equipped with a transient suppression circuit that effectively suppresses various surge pulses, ensuring reliable operation in harsh environments.
SPV1080-WB Series Analog Output Module delivers 4/8 channels of analog output signals. The module incorporates an advanced DAC converter, providing a 16-bit output resolution with accuracy better than 0.1%. It features triple isolation between power supply, input, and output circuits. Designed to output analog signals compatible with field equipment, it meets the demands of applications requiring high signal integrity, including industrial sites, medical electronics, security monitoring, smart buildings, smart homes, power monitoring, and process control scenarios.
This product requires an independent power supply and adopts a DIN 35mm standard rail mounting method, enabling simple on-site installation and flexible use to meet the demands of various application scenarios.
