Product Description
The Festo VAEM-V-S8EPRS2 is an electronic valve control module with integrated, adjustable holding current reduction, designed to control up to 8 solenoid valves with exceptional precision . Featuring a temporal resolution of only 0.2 ms and valve control via current rather than voltage, this module enables extremely high precision for demanding applications such as dispensing, while parameterisation, diagnostics, and control are accessible via Ethernet (Modbus TCP), RS232, and a graphical user interface .
Key Features & Advantages
8 Outputs with Per-Channel Parameterisation: Provides up to 8 outputs, each individually configurable for pick-up current (20–1000 mA) and holding current (20–400 mA). A programmable calibration factor can be set per channel to compensate for individual valve opening times or manufacturing tolerances .
Extremely High Precision (0.2 ms Resolution): Achieves a time resolution of only 0.2 ms and controls valves via current rather than voltage. This enables repeatable switching behaviour, even in complex processes like micro-dispensing .
Integrated Holding Current Reduction: Automatically reduces the current after the valve is switched (pick-up phase ≤100 ms). This cuts energy consumption by up to 75% and minimises heat input, protecting sensitive media and reducing thermal stress on the coil .
Simple Setup via Ethernet (Modbus TCP) and RS232: Two independent communication interfaces are integrated: an RJ45 port (Modbus TCP, 10/100 Mbit/s) for high-level network integration and an M8 (4-pin, A-coded) serial port (RS232) for direct PC connection. A web GUI allows for intuitive parameter setting and live diagnostics .
Compact (92 x 100 x 28 mm) and Robust (IP20): Housed in a lightweight (98 g) black PA housing, the module offers screw-through-hole mounting for versatile installation. It features comprehensive diagnostics, including LED indicators (Error/Run) and bus-based error detection (wire break, short circuit, under-voltage) .
