DPI-202 – Dual Channel Digital Process Indicator / Controller

Short description: A rugged microcontroller-based dual channel indicator-controller with two 4–20 mA inputs, four relay outputs, retransmission, and optional RS485 MODBUS connectivity. Compact panel mount unit, also available in flameproof enclosure.

Key Features

• Microcontroller-based dual channel process indicator-controller.
• Accepts 2 × 4–20 mA DC linear inputs (2-wire / 4-wire).
• Two independent 4-digit, ½” LED displays (one per channel).
• User configurable span, zero, and decimal point for both inputs.
• Four relay outputs (230VAC, 1A) with settable hysteresis; NO/NC option (factory set).
• Isolated 4–20 mA retransmission output for each channel.
• Optional RS485 MODBUS RTU communication (optically isolated).
• Built-in 24VDC, 50 mA transmitter power supply (for both inputs).
• EEPROM storage for all parameter settings.
• Optional flameproof enclosure available.
