ABB HESG447260R2 70BA01C-S PROCONTROL P13 Bus End Module

Description

The ABB HESG447260R2 70BA01C-S is a specialized bus termination unit designed for integration within the PROCONTROL P13 automation and control platform. The HESG447260R2 70BA01C-S serves as a vital signal conditioning and bus-end component, ensuring proper bus impedance matching and signal reflection suppression across the internal backplane bus. Utilizing a 24 V DC auxiliary supply with low power consumption, it maintains reliable noise immunity and system signal integrity for critical industrial and power generation applications.

Features

• Specialized termination design for the PROCONTROL P13 system bus.
• Low current consumption of 40 mA or less at 24 V DC supply.
• High surge withstand capability of 2 kV (1.2/50 us).
• Integrated electrical isolation of 500 V DC between bus and logic circuits.
• Extended operating temperature range suitable for harsh industrial environments.

Applications

• PROCONTROL P13 control and monitoring system racks.
• Signal conditioning and termination in power plant automation architectures.
• Backplane communication protection for industrial process control racks.

Technical Specifications

Installation Guidelines

• Ensure system auxiliary supply power is turned off before inserting or removing the unit from the rack chassis.
• Install the unit securely in the designated bus end slot of the PROCONTROL P13 rack to maintain correct bus impedance.
• Maintain proper rack grounding and shielding practices to preserve the specified 2 kV surge withstand rating.
• Ensure ambient temperature within the cabinet remains within -20 degC to +70 degC during operation.
