PLCs, Power Supplies & Others

The ABB DTDX 707A 61430001-WG drive interface module connects controllers to motor drives. This unit weighs 0.52 kg and measures 18.0 cm x 12.0 cm x 3.8 cm. It provides 1 fiber optic interface and 1 serial communication port. The module contains one main processor and two optical transceivers. For energy storage, it includes three 47µF tantalum capacitors. Consequently, the ABB DTDX 707A 61430001-WG maintains communication during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the ABB. Use this data for your system integration planning.

Fiber Optic Communication Features

The ABB DTDX 707A 61430001-WG uses a 820 nm fiber optic transceiver for noise-free communication. This interface supports cable lengths up to 2000 meters. Therefore, you can place drives far from the main controller without signal degradation. Fiber optics provide complete immunity to electrical interference. Consequently, this module suits high-noise environments like welding cells and VFD rooms.

Serial Communication Features

The RS-485 serial port supports baud rates from 9600 to 115200 bps. You can select either ABB proprietary protocol or Modbus RTU. Thus, the module integrates with both ABB drives and third-party devices. The serial interface includes 2500V RMS isolation from the logic circuitry. Hence, ground loops will not affect communication reliability.

Power and Energy Storage

The ABB draws 250 mA from a 24V DC supply. Hence, its total power consumption equals 6.0W. The three 47µF tantalum capacitors provide 8 milliseconds of hold-up time. This short backup protects configuration data during minor voltage sags. Furthermore, the module includes overvoltage and reverse polarity protection.

Installation and Connectivity

You can mount the ABB DTDX 707A 61430001-WG on a standard DIN rail. Alternatively, secure it with M4 screws through its mounting holes. The ST connector accepts standard 1 mm plastic fiber optic cable. The 9-pin D-sub port handles serial connections to drives or networks. For best performance, keep fiber bends above 25 mm radius. The ABB DTDX 707A 61430001-WG works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This drive interface module operates reliably from -10°C to +55°C. It also withstands 90% relative humidity without condensation. The module survives vibration up to 2g from 10 to 500 Hz. Therefore, the ABB DTDX 707A 61430001-WG suits harsh industrial environments perfectly.
