Emerson A6740 / A6740-10 16-Channel Output Relay Module

The 16-channel output relay module is designed for high reliability of the plant's most critical rotating machinery.

This 2-slot monitor is used with the AMS 6500 to form a complete API 670 machinery protection monitor.

Applications include steam, gas, compressor and hydraulic turbine machinery.

Any channel clear, alarm or warning signal can be selected as an input to the 16 channel output relay module.

Uses Boolean logic, applies time delays and selects output relays

Easy-to-use software provides a graphical logic display that graphically guides the user through the configuration.

The AMS 6500 Machinery Health Monitor is an integral part of PlantWeb® and AMS software.

PlantWeb provides comprehensive machinery health operation in conjunction with the Ovation® and DeltaV™ process control systems.

AMS software provides maintenance personnel with advanced predictive and performance diagnostic tools, enabling them to determine machine failures early with confidence and accuracy.

3U-sized 2-slot plug-in module reduces cabinet space requirements by half compared to traditional 6U cards
