Process Control and DCS Characteristics
4-20 mA HART loop protocol: The module maintains stable DC voltage rails, ensuring that downstream measurement and HART communication loops remain energized during primary power transitions.
FOUNDATION Fieldbus / Profibus PA connectivity: The backup architecture provides uninterrupted power to fieldbus segment interfaces, preventing link drops during facility power fluctuations.
Channel-to-channel isolation: Internal circuitry includes isolation to prevent fault propagation from the battery bank to the primary control bus during charging or discharge cycles.
Cold junction compensation (CJC): The module assembly is engineered to maintain thermal stability within the cabinet, supporting accurate CJC performance in adjacent analog input modules.
Frequently Asked Questions
Q: Can the battery bank be serviced while the UCN system is operational?
A: Yes. The module includes a disconnect connector to facilitate transition and maintenance. Ensure load current is within specified limits before executing manual disconnects.
Q: Is the 48 VDC output regulated by the module?
A: The module functions as a battery bank. Voltage levels are dependent on the state of charge of the internal battery cells. Ensure that connected HPM/APM equipment is rated for the nominal 48 VDC discharge range.
Field Installation Guidelines
Mounting: Secure the battery backup rack into the designated UCN cabinet position. Verify that the weight of 15.4 kg is fully supported by the chassis rails and that all fasteners are torqued to prevent shift under mechanical stress.
Grounding: Bond the module chassis directly to the cabinet protective earth (PE) bus using a low-impedance braided strap. A solid ground connection is mandatory to maintain the safety potential of the DC battery bus.
Wiring: Connect the disconnect connector to the primary control bus, ensuring that cable routing maintains physical separation from high-voltage AC input lines to minimize noise coupling into the DC backup rails.
