Model Type: RMU-110 Repeater Mounting Unit -Harmony Block I/O
ABB DC Industrial Drives
The DCS800 DC industrial drive is the latest drive from ABB, combining the newest control technology
with a thyristor power platform that has been factory-proven all over the world.
The DCS800 boasts a wider power range than any other DC drive on the market.
The hardware and software are designed with you, the user in mind.
Special features make installation and configuration simple and allow you to customize the application to your needs.
The DCS800 Panel Drive is a preengineered solution for quick and easy design and installation.
All required peripheral components are included on a space-efficient back panel,
ready to be mounted into an industrial enclosure The drive is an excellent replacement for the Reliance Electric® FlexPak 3000®.

All inputs are potentially isolated via optocouplers. If a common loop is required, this can be realized with the external short-circuit connector supplied.
Inputs 1 ... 8 have current sources for oxide film disconnection. These current sources are active within 10 ms of the input signal.
If the input signal changes more frequently than every 30 seconds, the on-time of the current sources is reduced.
Input currents of the 1.5 mA type are chopped to minimize power dissipation. As a result, the average input current is reduced to 0.4 mA.
The average input current and the oxide disconnect current remain constant over the input voltage range. The light emitting diodes are divided into two columns. the LEDs follow the input directly.
