Usage Method

The ABB UNITROL UN 0090a-P V.1 Summing Module is a simple device to use. The input signals are connected to the screw terminals on the module. The output signal is connected to the screw terminal labeled “OUT”. The module is powered by a 24 V DC supply.

Product Application

The ABB UNITROL UN 0090a-P V.1 Summing Module can be used in a variety of applications, such as:

• Temperature control: To sum the signals from multiple temperature sensors to get an average temperature reading.
• Pressure control: To sum the signals from multiple pressure sensors to get an average pressure reading.
• Flow control: To sum the signals from multiple flow sensors to get an average flow rate reading.
• Process control: To sum the signals from multiple sensors to get a single signal that represents a process variable.

Examples

Here are some examples of how the ABB UNITROL UN 0090a-P V.1 Summing Module can be used:

• In a temperature control system, the summing module could be used to sum the signals from multiple temperature sensors in a room to get an average temperature reading. This average temperature reading could then be used to control a heater or air conditioner.
• In a pressure control system, the summing module could be used to sum the signals from multiple pressure sensors in a pipe to get an average pressure reading. This average pressure reading could then be used to control a pump or valve.
• In a flow control system, the summing module could be used to sum the signals from multiple flow sensors in a pipe to get an average flow rate reading. This average flow rate reading could then be used to control a pump or valve.
• In a process control system, the summing module could be used to sum the signals from multiple sensors, such as temperature sensors, pressure sensors, and flow sensors, to get a single signal that represents a process variable. This process variable signal could then be used to control a process, such as a chemical reaction or a manufacturing process.
