EPRO A6740/12 | 16-Channel Output Relay Module
The EPRO A6740/12 is a robust 16-channel output relay module designed by Emerson (EPRO) for advanced machinery protection systems. Integrated into the AMS 6500 platform, it links monitoring systems to external devices such as alarms, shutdown circuits, and actuators.
This module reacts to real-time vibration, speed, and displacement data, triggering protective actions immediately when pre-configured thresholds are exceeded. Its modular design supports hot-swappable replacement, ensuring uninterrupted operation in critical industrial environments. The A6740/12 is ideal for applications in power generation, petrochemical plants, manufacturing, and offshore operations.
Its compact 3U Eurocard form factor fits standard DIN racks while providing high reliability, LED diagnostics, and status monitoring for each channel. With IP65 sealing and compliance to API 670, IEC vibration/shock standards, CE, and RoHS, this relay module maintains stable performance under harsh conditions.
