Description
1. Product Description
⚙️ The GE Fanuc VMIVME-2128 is a 128-bit high-voltage digital output board designed for VMEbus-based industrial control and embedded computing systems. It provides high-density discrete output channels for controlling compatible external loads, including relays, solenoids, and indicators.
🔧 The board features open-collector output drivers, built-in test (BIT) logic, output register readback, automatic surge-current shutdown, thermal protection, and output clamp diodes for inductive loads. It uses a 6U VME form factor and is suitable for maintaining legacy industrial automation and test systems. The original VME-2128 reached end of life on April 19, 2018; the VME-2128A is identified by Abaco Systems as a form-fit-function replacement, subject to configuration verification.
