8C-TDODA1 | Honeywell | Digital Output IOTA Coating

Honeywell 8C - TDODA1 is a 32-channel digital output module with bus output. It belongs to the Experion LX distributed control system (DCS) 8 series I/O series and uses coating technology. The following is a detailed introduction to it:

Functional features:

Output control: supports multiple output control methods, such as latching, pulse, and pulse width modulation (PWM). In latch mode, the module will maintain the state of the last output until a new command is received; the pulse mode can generate a pulse signal of short duration; the PWM mode can control the power of the load by changing the on-time of the output signal, which is often used in scenarios such as lighting dimming or motor speed control.

Safety features: It has extensive diagnostic functions to ensure data integrity and reliable operation. The module has optional redundancy to provide backup in case of module failure. Each channel has a safe state (failopt) behavior configuration, which can choose to maintain the last value or switch to a safe value in case of module failure.

Electrical characteristics: The output is a 24V DC digital signal, and all outputs share a common ground. Power can come from system power or external 24V power, and galvanic isolation can be achieved when using external power.

Technical specifications:

Output channels: 32 channels.

Output type: Source.

Voltage rating: 24V DC.

Module current rating: 105mA.

Load voltage: Maximum 30V DC.

Load current: Each channel is short-circuit protected, using fuses (one fuse per 8 channels, 4 fuses for a 32-channel module), and the maximum load current per channel is 100mA.

Electrical isolation: The isolation voltage between the system and the field is 1000V AC RMS (when using user-supplied field power), and there is no isolation between the system and the field when using internal system power.

Operating temperature: 0℃ to 60℃.

Storage temperature: -40℃ to 85℃.

Coating Advantages: 8C - TDODA1's coating is a conformal coating that protects electronic circuits from moisture, dust, chemicals and extreme temperatures, improving the module's reliability and durability in harsh industrial environments.

This digital output module is commonly used in industrial automation control systems to reliably switch 24V digital output signals to control a variety of devices such as process equipment, solenoid valves, intermediate relays, etc.
