Overview
The DeltaV CHARM I/O Module (FM19ATEX0173U) is a high-reliability digital automation unit engineered for hazardous environments. It is designed to operate safely in Zone 2 and Division 2 areas, making it ideal for process automation systems that require robust digital signal acquisition and control. The module seamlessly integrates with DeltaV series systems for efficient process management.
Installation and Maintenance
-
Installation Warning: Module must not be inserted or removed while the system is powered in hazardous areas. Ensure I/O loops are energy-limited.
-
Keying System: Ensures CHARM module compatibility with the terminal block; automatically sets during first installation. Removing the terminal block allows key reset for different module types.
-
Maintenance: No user-serviceable parts; calibration is not required.
Applications
Designed for chemical, oil, gas, and other flammable environments where reliable digital input/output performance is critical. Ensures safe operation in high-risk areas.
