Honeywell 10205/2/1

Usage Parameters

HONEYWELL 10205/2/1 is a fail-safe analog output module with clear usage parameters; it should be connected to a 5 V DC power supply with a maximum current of 30 mA, and a 24 V DC power supply with a maximum current of 65 mA, and each active output requires an additional 30 mA. It consists of two output channels that are completely isolated from the power supply voltage, and the 0V1 and 0V2 pins are connected. It can be configured as an output specification of 0 - 20 mA or 4 - 20 mA, and each output channel is equipped with a 12-bit D/A. The shutdown current is less than 0.05 mA. When loop-powered (active), the maximum loop resistance is set to 1k ohm and the maximum output voltage is 30 V DC. Passive external power supply allows a maximum voltage of 40 V DC with a minimum voltage drop of 7.5 V. The maximum current is 0.5 mA at WDG input current.

Product Features

Capacity Fail Safe: The module includes a fail safe function for configuring process safety times. The correct output value of the analog outputs (current value ± 5%) is monitored to determine power-off capability and crosstalk between analog outputs. In addition, each analog output is equipped with an auxiliary power-off device, allowing the watchdog and/or processor to power off the output regardless of the applied value. Although this feature may have been discussed elsewhere, it undoubtedly enhances the reliability and safety of processes in critical applications.

Analog Output Control: With two 0(4)-20mA output channels, high-precision analog signals are available for controlling external devices or processes in a variety of situations. The 12-bit D/A converters in the outputs ensure high accuracy and resolution, allowing fine adjustments to flow, pressure, temperature or speed in industrial processes.

Calibration and Monitoring: The module is equipped with P2 and P3 potentiometers for calibration. It can be calibrated with the help of the calibration option in the "View FSC System and Process Status" program, along with the expander module, expander flat cable and multimeter. In addition, an A/D converter is included in each output channel, which allows for convenient monitoring of the output current, providing feedback for in-depth diagnostics of the system and ensuring perfect accuracy of its operating control loop.

Compatibility and Integration: The 10205/2/1 module is part of the Honeywell product family and is fully compatible with other Honeywell controllers, I/O modules and application software. Its integration with existing Honeywell DCS systems is very simple, allowing for seamless communication and coordinated processes within the automation system.

Application Scope

HONEYWELL 10205/2/1 can be widely used in many industries. In the process control industry, it controls valves, actuators or any other field equipment in chemical plants, refineries and pharmaceutical plants, where precise control of process conditions is critical to product quality and production efficiency. An example of its application may be regulating the flow of chemicals in a reaction process or controlling the pressure of a pipeline system. In the field of power generation, the module can control the generator excitation current, turbine speed or cooling water flow, thus helping to improve the operation stability and efficiency of the factory. In the field of building automation, it can be used to control HVAC (heating, ventilation and air conditioning) operation; it can automatically adjust the air flow and temperature in the building to keep the indoor environment comfortable and save energy.
