United Electric E121-2BSB Temperat

The United Electric E121-2BSB is a temperature control unit designed for precise temperature regulation in various industrial and commercial applications. United Electric is known for producing high-quality temperature controllers, pressure switches, and other process control devices used in a wide range of industries, including HVAC, manufacturing, and laboratory settings.

Key Features of the United Electric E121-2BSB Temperature Control:

1. Temperature Sensing: The E121-2BSB is designed to monitor and control temperature within a specific range. It uses temperature sensors (typically RTDs or thermocouples) to detect the temperature of a given environment.

2. On/Off or Proportional Control: The E121-2BSB can provide either on/off control (for simpler applications) or proportional control, depending on the configuration. Proportional control ensures smoother and more efficient temperature regulation, ideal for environments requiring precise temperature maintenance.

3. Adjustable Setpoint: Users can set a desired temperature range or setpoint. The controller will adjust the heating or cooling output based on this setpoint to maintain the desired temperature.

4. Wide Application: It can be used in various industrial processes, including temperature regulation for ovens, tanks, or process equipment. It’s also useful in HVAC systems for managing heating and cooling.

5. Display and Interface: The control typically includes a user-friendly display, allowing operators to easily set and monitor the current temperature. Some models also feature digital displays for precise reading and adjustment.

6. Switching Capacity: The E121-2BSB usually includes high switching capacities for controlling various heating or cooling devices like relays, motors, or heating elements.

7. Durable and Reliable: Designed to operate in industrial settings, these controllers are built to withstand harsh environments, including extreme temperatures, humidity, and vibrations.

8. Adjustable Deadband: Many temperature controllers like this offer an adjustable deadband to prevent excessive cycling of heating/cooling devices around the setpoint.

9. Electrical Specifications: The device generally operates on standard AC or DC voltage (depending on the model) and can be configured for specific voltage and current ranges, allowing it to be used in a variety of applications.

Common Applications:

• HVAC Systems: For controlling temperature in heating and cooling units, such as air handlers, furnaces, or chillers.
• Manufacturing: In processes where temperature control is crucial, like in ovens, furnaces, and chemical processing systems.
• Cold Storage: For precise temperature regulation in refrigeration or cold storage units.
• Laboratory Equipment: To control temperatures in incubators, ovens, or any temperature-sensitive processes.

Specifications (General for Models Like E121-2BSB):

• Temperature Range: Typically between -50°C to +200°C (depends on the sensor type).
• Accuracy: High accuracy within a set temperature range, often with tolerances of a few degrees or less.
• Output Type: Typically relay outputs for controlling external heating or cooling devices.
• Display: Digital or analog, with options for adjusting setpoints, deadband, and other parameters.
• Power Supply: Usually 24V DC or 110V to 240V AC depending on the model.
