The TDC3000, previously by Honeywell Siebel and now by Honeywell, is a Distributed Control System (DCS) utilized across industries for process control applications. Comprising a series of modules, these systems monitor, control, and optimize industrial processes. Here's an overview of TDC3000 modules and their functionalities:
Types of TDC3000 Modules:
-
I/O Modules (Input/Output): Interface between the TDC3000 system and field devices like sensors and actuators. They include:
- Analog Input (AI) Modules: Convert analog signals (voltage or current) from sensors into digital values for the controller.
- Analog Output (AO) Modules: Convert digital signals from the controller into analog signals (voltage or current) to control actuators.
- Digital Input (DI) Modules: Receive digital on/off signals from devices like limit switches and convert them for the controller.
- Digital Output (DO) Modules: Receive digital signals from the controller and activate relays or other digital devices in the field.
-
Communication Modules: Enable communication between different components within the TDC3000 system and potentially external systems. They may support protocols like Modbus or Ethernet.
-
Controller Modules (CPU Modules): Act as the system's brain, executing control logic programs. They process data from I/O modules, perform calculations, and send control signals to actuators based on programmed logic.
-
Power Supply Modules: Provide electrical power to various modules within the TDC3000 system.
Please note: The TDC3000 system has been in use for some time, and Honeywell may no longer actively manufacture all modules. However, PLC DCS Pro Ltd. still offers 100% brand-new original TDC3000 modules. Feel free to inquire for more information.
