process controllers RT1900-R

Product catalog summary

Overview: The Universal Programmable Controller RT1900-R by Comeco Inc. is a versatile microprocessor-based controller designed for industrial applications. It supports DIN-rail or wall mounting and features a 4-digit display, triple isolation, and universal programmable input.

Specifications: The RT1900-R accepts inputs from Pt100 sensors, 10 types of thermocouples, and various linear signals. It offers up to 3 relay outputs and 1 analog output, with control through ON/OFF and PID-fuzzy algorithms. The controller includes a RAMP/SOAK pattern control and a bumpless auto-manual change-over feature.

Communication: The device is equipped with an RS485 MODEBUS serial interface for configuration and networking, supporting up to 32 devices over a maximum distance of 1200 meters. A USB port is available for parameter storage.

Performance: The RT1900-R boasts a measurement accuracy of 0.3% from span and a temperature drift of 0.01% from span per 1°C. It features automatic software for cold junction and RTD line compensation, with a sample time of 250 ms.

Power Supply: The controller operates on a supply voltage of 85 to 265 VAC with a maximum consumption of 4 VA.

Inputs and Outputs: The device supports a wide range of input types and ranges, including various thermocouples and linear DC signals. It provides optical input isolation at 1500 VAC and offers multiple output configurations, including relay, solid state relay, MOS gate, and analog outputs.

Operating Conditions: The RT1900-R is designed to operate in ambient temperatures from 0 to 50°C and humidity levels from 20 to 85% RH. It can be stored at temperatures between -25 to 65°C and humidity up to 95% RH, non-condensing.

Design and Materials: The controller is housed in a plastic case with dimensions of 40x107x43 mm and a weight of up to 120 g. It is mounted on a 35 mm DIN rail or wall and uses screw terminals for wiring. The protection class is IP10.

Ordering Information: The RT1900-R can be customized with various features and options, including relay control and alarm outputs, control algorithms, serial interfaces, and analog control outputs. Customers are advised to contact Comeco for specific configurations and availability.
