ABB IM/C1900R-Q C1900 Series Circular Chart Recorders

Product Description

The ABB IM/C1900R-Q is a remote version of ABB’s robust C1900 series circular chart recorders. Designed for continuous monitoring and recording of critical process variables—such as temperature, pressure, or flow—the unit supports remote signal input, making it suitable for installations where the sensor or transmitter is located far from the recording site. The "R" denotes remote capability, while the "Q" indicates a specific configuration or option set related to measurement range, input type, or firmware variant.
