DP400S High Speed Load & Strain Meter, NFC Enabled
High Speed Load and Strain Meter, NFC Enabled
Supported Applications
The Omega DP400S is a high-speed indicator and panel meter designed for the acquisition and retransmission of process signals. It features fast transient response capabilities suitable for dynamic measurements involving strain-gauge sensors, including load cells and MelT sensors.
Operating Conditions & Performance
The DP400S operates within an ambient temperature range of 0-40 °C with a humidity rating of 35..95 RH%. The device is housed in Polycarbonate V0 material, providing an enclosure rating of IP54 for the front panel (with gasket) and IP20 for the box and terminals. It weighs approximately 165 g.
Configuration Options
The DP400S series is available in a standard 96 x 48 mm format, configurable for horizontal or vertical mounting. The unit integrates multiple signal processing and communication features:
• Analog Input: Software-configurable for strain-gauge (load cells or MelT sensors) with a maximum of 7.5 mV/V using a 5V power supply, supporting up to max 4 cells 350 Ω in parallel; also configurable for potentiometer input (min. 200 Ω).
• Outputs: Includes 2 Relays with contacts rated at 2A - 250 Vac resistive charge, and an analog output configurable as 0..20mA or 4..20mA.
• Digital Connectivity & Display: Features RS485 communication via Modbus-RTU protocol, a graphic OLED monochromatic yellow display (128 x 64 pixels), and RFID support.
• Power Supply: Accepts an extended range of 24..230 Vac/Vdc ±15% at 50/60 Hz via IN+ / IN- terminals.
The device includes programmable digital inputs and software functions such as totalizer and sum. Visualization options include bar graphs and process trends with programmable sampling time, accessible through an intuitive multilingual interface.
Key Product Differences
The series is represented by the DP400S model, which combines 2 Relays, a configurable mA output, 2 Digital Inputs (D.I.), RS485 connectivity, OLED display, and RFID functionality in a single unit. The device supports both horizontal and vertical mounting configurations within its standard dimensions.
