Description
Product Description
The VMIVME-4116 is a high-performance analog output board designed for industrial automation, control systems, and test applications. Manufactured by GE Fanuc (now part of Abaco Systems), the VMIVME-4116 delivers 8 channels of 16-bit resolution digital-to-analog conversion (DAC), enabling precise signal generation and control. Its dual-buffered architecture ensures stable output updates, while features like fast settling time (10 µs to ±0.003% FSR) and buffered voltage output (±10 V at 5 mA) make it ideal for applications requiring reliable analog signal conditioning. The VMIVME-4116 supports VMEbus compatibility and includes built-in test (BIT) capabilities via the AMX bus, enhancing system diagnostics. With applications in industries ranging from manufacturing to medical devices, the VMIVME-4116 combines accuracy, durability, and ease of integration.
