Eurotherm EPC3004 is a PID temperature controller designed for accurate temperature control in industrial applications. The device features a compact panel mount design with a size of 92 x 92mm, making it an ideal choice for space-constrained environments. In this article, we will explore the various features and specifications of the Eurotherm EPC3004 temperature controller.
Input and Output Capabilities
The Eurotherm EPC3004 temperature controller offers a range of input and output capabilities to meet the requirements of different industrial applications. The device comes with four universal inputs that can accept thermocouples, RTDs, or linear inputs. These inputs can be configured for different sensor types and ranges, allowing the device to work with a wide range of temperature sensors.
The device also offers four outputs that can be configured as DC voltage or current outputs, relay outputs, or SSR driver outputs. These outputs can be used to control heaters, coolers, or other process devices in the system. The relay outputs are rated at 5A, 250V AC, making them suitable for switching heavy loads.
PID Control Algorithm
The Eurotherm EPC3004 temperature controller uses a PID control algorithm to provide accurate temperature control in industrial applications. The PID algorithm allows the device to maintain the desired setpoint temperature by adjusting the output based on the difference between the setpoint and the process variable.
The device offers a range of tuning options to optimize the PID algorithm for different processes. The tuning options include manual tuning, auto-tuning, and adaptive tuning. The manual tuning option allows the user to adjust the PID parameters manually, while the auto-tuning option allows the device to automatically tune the parameters based on the process response.
User Interface and Display
The Eurotherm EPC3004 temperature controller features an intuitive user interface that allows easy configuration and operation of the device. The device comes with a 3.5-inch TFT color display that provides a clear view of the process variables, setpoints, and alarms. The display can show up to four process variables simultaneously, making it easy to monitor multiple parameters in real-time.
The user interface includes a range of function keys that allow easy navigation and operation of the device. The device also features a USB port that allows easy configuration and backup of the device parameters. The USB port can also be used to upgrade the device firmware.
Alarm and Event Management
The Eurotherm EPC3004 temperature controller offers a range of alarm and event management features to ensure safe and reliable operation of the system. The device comes with four configurable alarms that can be set up to trigger when the process variable exceeds or falls below a set limit. The alarms can be configured to operate as latching or non-latching and can be assigned to any of the four outputs.
The device also features event management capabilities that allow the user to log and monitor events such as alarms, setpoint changes, and parameter modifications. The event log can be viewed on the device display or downloaded to a PC via the USB port.
Power Supply and Environmental Specifications
The Eurotherm EPC3004 temperature controller operates on a 24V DC power supply and consumes a maximum of 8W of power. The device can operate in a temperature range of 0°C to 50°C and can withstand a maximum relative humidity of 80%.
