Honeywell 8C-TDOD51 32-Channel 24VDC Digital Output Module
Product Short Description
Technical Specifications
Power Supply Parameters: It uses a 24VDC power supply. The module has a current rating of 105mA, and the maximum load voltage it can bear reaches 30VDC, which can meet the power demand of continuous operation of multiple channels.
Channel and Signal Performance: It is equipped with 32 sink – type output channels. The maximum load current of each channel is 0.1A, and the total maximum load current of the entire module is 3.2A. The on – state voltage is no more than 1VDC when the current is 0.1A, the off – state leakage current is at most 5μA, and the maximum turn – on and turn – off time of the channel is 10ms.
Isolation and Protection Indicators: It is equipped with galvanic isolation of 1000VAC RMS or ±1500VDC between the system and the field. It is configured with 4 fuses in total, with one fuse for every 8 channels to achieve short – circuit protection, effectively preventing module damage caused by circuit faults.
Physical and Environmental Parameters: Its dimensions are 228.6mm×63.5mm×19.1mm, and its weight is 0.7kg. It can work in the temperature range of -40°C to 70°C, and the storage temperature range is -40°C to 80°C. It can operate normally in an environment with 0% – 95% relative humidity without condensation.
Multi – mode Output and Flexible Configuration: The module supports latched, pulsed and PWM output modes. Users can configure each channel independently. It also allows per – channel fail – safe configuration, where each channel can be set to hold the last value or switch to a safe state when a fault occurs, adapting to different industrial control requirements.
Strong Anti – interference and Stable Operation: The galvanic isolation design enhances the module’s ability to resist electrical noise. Even in industrial sites with strong electromagnetic interference, it can avoid signal distortion and ensure the accuracy of output signals, maintaining stable operation of the connected equipment.
Visual Monitoring and Convenient Maintenance: It is equipped with LED indicators for each output channel. The indicators can intuitively reflect the working status of each channel, enabling maintenance personnel to quickly locate faults during daily inspection and reduce maintenance time and difficulty.
Seamless Redundancy Switching: In redundant application scenarios, the output switching gap to the field is 0ms, realizing no – interruption switching. This ensures that the control process will not be affected when the system switches between redundant modules, maintaining the continuity of industrial production.
Application Scenarios
Petrochemical Industry: It is integrated into the Experion control system of oil refineries and chemical plants. It outputs digital signals to control the switching of solenoid valves and relays in pipelines and reaction kettles, regulating the transportation of raw materials and the progress of chemical reactions, and ensuring the safety and order of production processes.
Automotive Manufacturing Industry: It is applied to automated assembly lines and welding production lines. It controls the start – stop of robotic arms, the action of clamping devices and the operation of welding equipment through digital output signals, ensuring the accuracy and synchronization of each process in automobile production.
Power Generation Industry: In thermal power and hydropower plants, it is used in the control systems of boilers, water pumps and other equipment. It controls the opening and closing of related valves and the operation of auxiliary equipment, adjusts the fuel supply and water circulation speed, and ensures the stable operation of power generation equipment.
Food and Beverage Industry: It is used in automated production lines such as beverage filling and food packaging. It controls the operation of filling machines, sealing machines and conveyor belts. Through stable digital output, it ensures the consistency of filling volume and packaging speed, improving production efficiency and product quality.
Water Treatment Industry: In sewage treatment plants, it controls the operation of dosing pumps, aerators and sludge discharge equipment. It sends out switching signals according to the water quality detection data to realize the automatic control of dosing, aeration and other links, ensuring that the treated water meets the discharge standards.
