Input and Output Capabilities
The Eurotherm EPC3004 temperature controller features four universal inputs that can accept a range of input types, including thermocouples, RTDs, and linear inputs. These inputs can be configured for different sensor types and ranges, making the EPC3004 a versatile choice for a wide range of temperature control applications.
The device also features four outputs that can be configured as relay 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.
Power Supply and Environmental Specifications
The Eurotherm EPC3004 temperature controller operates on a 24V DC power supply, making it a reliable and cost-effective option for industrial applications. The device consumes a maximum of 8W of power, making it an energy-efficient choice for temperature control systems.
The device can operate in a temperature range of 0°C to 50°C and can withstand a maximum relative humidity of 80%, making it suitable for use in a wide range of industrial environments.
Other Key Features
In addition to its input and output capabilities, power supply, and PID control algorithm, the Eurotherm EPC3004 temperature controller also offers a range of other key features that make it an ideal choice for industrial temperature control applications.
These features include 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.
