Bailey Module Mounting Unit IEMMU11

The Bailey Module Mounting Unit IEMMU11 is a robust and versatile component designed to house and support up to 12 system modules within the ABB Infi 90 Distributed Control System (DCS). Its rear-mounted configuration ensures efficient space utilization and streamlined integration into standard 19-inch industrial cabinets.

Key Features

• Module Capacity: Accommodates up to 12 system modules, or 10 system modules alongside a maximum of two power modules, such as IEPAS02, IEPDS01/02, IEPAF02, and IEPDF01/02.
• Power Distribution: Efficiently distributes regulated DC voltages (+5V, +15V, –15V, and +24V) and primary power inputs of 120/240 VAC or 24/48 VDC to the installed modules.
• Signal Management: Facilitates the distribution of I/O expander bus, module bus, and Controlway signals, ensuring seamless communication between modules.
• Environmental Resilience: Operates reliably within a temperature range of 0°C to 70°C (32°F to 158°F) and a relative humidity of 5% to 95% up to 55°C (131°F), non-condensing.
• Standardized Mounting: Designed for easy installation in standard 483-mm (19-inch) cabinets, adhering to industry mounting standards.
