IM/C1900INS ABB Circular Chart Recorder High-Impedance Input

Product Overview

The ABB IM/C1900INS (IMC1900INS) functions as a high-precision data acquisition instrument within the established Commander 1900 series. This module enables the simultaneous visual recording and digital monitoring of up to four independent process signals. It tracks critical variables such as temperature, pressure, and flow, translating electrical inputs into permanent records on a circular paper chart. Engineered for high-integrity industrial environments, the IM/C1900INS maintains signal purity through sophisticated input circuitry, ensuring that low-level sensor data remains accurate over long-term recording cycles. We supply this unit as 100% brand new and original, housed in factory-sealed packaging to guarantee Swiss-engineered performance from the moment of installation.

Technical Specifications

Engineering Advantages

The IM/C1900INS solves fundamental data logging challenges in high-interference industrial settings:

• Universal Input Flexibility: The module accepts a wide variety of signal types without requiring external converters. It directly interfaces with thermocouples and 2-wire transmitters, simplifying the overall wiring architecture.

• Signal Distortion Mitigation: High input impedance (>10 M ohm for voltage inputs) prevents the recorder from loading the source circuit. This ensures the logged data reflects the true process state, even when dealing with high-impedance sensors or long cable runs.

• Integrated Loop Power: Terminal 6 provides dedicated transmitter power, eliminating the need for auxiliary DC power supplies for 2-wire field instruments. This reduces cabinet complexity and potential points of failure.

• Redundant Status Visualization: In addition to the physical pen traces, high-visibility digital displays and flashing alarm LEDs provide immediate status updates. This multi-layered feedback ensures operators detect process excursions even in low-light or high-distraction environments.

• Rugged Mechanical Construction: The unit utilizes industrial-grade materials to withstand the vibration and temperature fluctuations common in process control rooms and secondary field enclosures.

FAQs

• Does the IM/C1900INS come with pre-installed pens and charts?

  Standard original units arrive in factory-sealed packaging. We recommend confirming your specific chart rotation speed and pen color requirements during the order process to ensure immediate commissioning upon arrival.

• Can this recorder power my field transmitters directly?

  Yes. The IM/C1900INS includes an integrated power supply via terminal 6, designed specifically to drive 2-wire transmitters, which streamlines your field loop installation.

• What is the typical shipping lead time for an original ABB unit?

  We dispatch 100% original IM/C1900INS units via DHL, FedEx, or UPS within 3 to 14 days, providing full tracking and insurance for global delivery.

• Is the input impedance high enough for precision mV sensors?

  Absolutely. With an impedance exceeding 10 M ohms for millivolt inputs, the module prevents signal attenuation, making it ideal for high-precision thermocouple and low-voltage monitoring.
