Basic Information

Model and number: Model number is CAO 10, product number is P 72123-4-0788 723.

Dimensions and weight: Dimensions approx. 20.3cm x 5.1cm x 30.5cm, weight approx. 1.2kg.

Place of origin and delivery: Germany, delivery to Webster, NY, USA.

Functional Features

Signal Output Capability: 16 analogue output channels, capable of outputting 0/4-20mA signals, enabling precise control of multiple analogue devices.

Accuracy and Stability: 12-bit D/A converter, zero deviation <=±30µA, range deviation <=±0.2%, with high signal conversion accuracy and stability.

Isolation protection: The output channels are isolated from each other, and the isolation voltage is rated at 250Veff, which can effectively prevent inter-channel interference and fault spreading.

Load monitoring: It can monitor the load situation and issue alarms when the load is abnormal to ensure the normal operation of the system.

Communication function: support HART protocol, can communicate with field equipment to achieve remote monitoring and parameter setting.

Application Fields

Industrial automation: in the chemical, pharmaceutical, food and beverage and other process control industries, can be used to control flow, temperature, pressure and other parameters; in the automotive manufacturing, electronics manufacturing and other discrete manufacturing industries, can be used to control the motor speed, valve opening and so on.

Energy management: in the power system, it can be used to control the generator output voltage, current and other parameters; in the energy management system, it can be used to control the distribution and use of energy, to achieve energy saving and emission reduction goals.

Building automation: It can be used to control the temperature, humidity and other parameters of the air-conditioning system, as well as the brightness of the lighting system, etc., so as to improve the energy efficiency and comfort of the building.

QAL3 monitoring is available as an option in the gas analyzer. It is  used to fulfill the requirements according to EN 14181 for storage  and analysis of device adjustment data. The QAL3 monitoring option features the following functions:
