The DEIF TDG-210DG/2 is an insulation amplifier and DC/DC amplifier designed for various industrial applications. This quick start guide provides essential information for its installation and use, focusing on its technical specifications, wiring, and operational requirements.
Function Description
The TDG-210DG/2 acts as an insulation amplifier, providing electrical isolation between the input and output signals. It also functions as a DC/DC amplifier, converting and amplifying DC signals. This device is crucial for protecting sensitive equipment from ground loops and transient voltages, ensuring signal integrity and system reliability in challenging industrial environments. Its primary role is to take a standard current input (4-20 mA) and convert it into a voltage output (-10 to 10 V), while maintaining electrical isolation.
Important Technical Specifications
- Type: TDG-210DG/2
- DEIF Order Number: 100190212.10 (This number is unique to the transducer and should be referenced when contacting DEIF for support or inquiries).
- Input: The device accepts a current input ranging from 4 to 20 mA. The impedance of the input circuit (Ri) is a critical factor for proper signal acquisition.
- Output: The TDG-210DG/2 provides a voltage output ranging from -10 to 10 V.
- Load Specifications:
- For the 4-20 mA input, the load is specified as 50 Ohm.
- For the -10 to 10 V output, the load must be greater than 500 Ohm.
- Voltage Output Loads: The load connected to the voltage output must not drop below the stated resistance (500 Ohm) to ensure accurate and stable operation.
- Current Output Loads: While the primary output is voltage, if the device were to have a current output, the load would not be allowed to exceed a stated resistance.
- Supply: The device requires a 24 VDC auxiliary voltage supply.
- Power Consumption: The power consumption of the device is 2.5 W.
- Serial Number: Each unit has a unique serial number (e.g., 1106582.0001) and a manufacturing date (e.g., 2017/36), which are important for traceability and warranty purposes.
- Dimensions: The physical dimensions of the transducer are approximately 108.0 mm (length) x 85.0 mm (width) x 61.0 mm (height), with specific details for mounting and terminal access. The compact design allows for efficient use of space in control cabinets.
- Environmental Considerations: The transducer is designed for installation in a well-aerated location to prevent overheating and ensure optimal performance and longevity.
Usage Features
- Input/Output Configuration: The device is configured for a standard 4-20 mA current input, which is a common signal type in industrial automation for transmitting process variables over long distances with good noise immunity. The output is a -10 to 10 V voltage signal, suitable for interfacing with PLCs, data acquisition systems, and other control devices.
- Terminal Connections: The device features clearly labeled terminals for easy wiring:
- Input (A1, A2): These terminals are for connecting the 4-20 mA input signal. A1 is typically the positive terminal, and A2 is the negative.
- Output (B1, B2): These terminals provide the -10 to 10 V output signal. B1 is typically the positive output, and B2 is the negative.
- Supply (X1, X2): These terminals are for connecting the 24 VDC auxiliary power supply. X1 is typically the positive supply, and X2 is the negative (ground).
- DIN Rail Mounting: The TDG-210DG/2 is designed for DIN rail mounting, a standard practice in industrial control panels for quick and secure installation. When multiple transducers are mounted on the same DIN rail, it is crucial that the DIN rail is always in the horizontal position.
- ESD Precautions: Normal ESD (Electrostatic Discharge) precautions must be taken when handling the transducer to prevent damage to its sensitive electronic components. This includes using anti-static mats and wrist straps.
- Recommended Fuse: A recommended fuse of 2 A should be used for the supply circuit to protect the device from overcurrents.
Maintenance Features
- Lifetime and Optimal Function: To ensure a long lifetime and optimal function of the TDG-210DG/2, several installation requirements must be met:
- Spacing: A minimum distance of 10 mm (and a recommended minimal distance of 30 mm) must be maintained between mounted transducers or other equipment. This spacing is essential for adequate heat dissipation and to prevent mutual interference.
- Ventilation: The transducer must be installed in a well-aerated location to facilitate cooling and prevent overheating, which can degrade performance and shorten the device's lifespan.
- DIN Rail Orientation: As mentioned, when multiple units are installed, the DIN rail must be in a horizontal position to ensure proper thermal management and consistent performance across all devices.
- Troubleshooting: In case of issues, the DEIF order number and serial number are essential for obtaining support from DEIF, allowing technicians to quickly identify the specific model and production batch for efficient troubleshooting and part replacement.
- Robust Design: While not explicitly detailed as a maintenance feature, the industrial design of DEIF products generally implies a certain level of robustness and reliability, minimizing the need for frequent maintenance. Regular checks of wiring connections and environmental conditions are typically sufficient for ongoing operation.
