A3800

Compact size on-line monitoring system

A3800 Online Monitoring System - Adash

The A3800 unit is the compact size on-line monitoring and diagnostic system. It is designed to increase machine reliability. The small size of the A3800 enables to mount it directly on the DIN rail. The optional number of channels (4, 8, 12, 16) is available on the A3800 unit. The same number of AC and DC channels are always available. The 4 tacho sensors can be used in 16 channel option. The number of channels is determined by the license file. When the user wants to increase the number of channels, then only the new licence file is written to unit memory. No unit disassembling is required. Each group of 4 channels measures fully simultaneously. Individual groups of 4 channels are multiplexed.

The A3800 unit can be also used as a powerful multichannel analyzer. The setting and control is made by VA4 Pro - Virtual Unit software (free download).
