Overview
Configured for multi-channel process signal recording and chart-based data presentation, the ABB C1900R (C1900R Circular Chart Recorder) provides direct physical recording through up to 4 independently configured pen traces. The recorder uses a 10.5-inch circular chart, programmable chart rotation, modular I/O cards, and a 6-digit LED operator display for process values, status information, and alarm indication.

ABB Industrial I/O and Firmware Compatibility
The ABB C1900R uses modular plug-in input and output cards to adapt the recorder to installed process signal requirements. This architecture allows analog inputs, digital inputs, relay outputs, and retransmission functions to be configured through compatible hardware options.
In addition, the recorder separates recording functions through independently configured pen ranges. Therefore, each trace can use a measurement range appropriate to its connected process signal. The modular hardware also supports on-site maintenance through plug-in cards and snap-in pen holders.
Frequently Asked Questions
Q: How many process signals can the ABB C1900R record simultaneously?
A: The C1900R supports up to 4 trace recording. Each pen can use an independently configured recording range.
Q: Can the chart rotation speed be changed for different recording periods?
A: Yes. The chart rotation time is programmable from 1 hour to 32 days per revolution.
Q: What types of I/O functions are available?
A: The recorder uses modular plug-in cards for analog inputs, digital inputs, relay outputs, and retransmission functions, depending on the installed configuration.
Field Installation Guidelines
Install the ABB C1900R on a stable wall, pipe, or panel structure that supports the recorder weight and enclosure dimensions. Maintain sufficient access around the enclosure for chart replacement, pen service, wiring, and plug-in card maintenance.
Route signal cables separately from high-power conductors and switching circuits to reduce electrical interference. Use shielded signal wiring where required by the connected instrumentation, and terminate cable shields according to the site grounding design.
Verify the configured power supply before applying electrical power. The available supply configuration is 85 to 265 VAC or 24 VDC, depending on the recorder version. Confirm input, output, and retransmission card assignments before connecting field wiring.
Maintain the enclosure sealing arrangement after installation, especially in washdown or high-moisture areas. The NEMA 4X / IP66 protection rating depends on correct enclosure assembly and cable entry sealing.
