The TWDDDO8TT expands the output capacity of Schneider Electric's Twido automation platform with 8 discrete transistor outputs. This module efficiently drives solenoids, relays, indicator lights, and other low-power DC loads. Its sourcing logic configuration matches standard industrial device wiring practices. Furthermore, the TWDDDO8TT incorporates comprehensive protection features and photocoupler isolation, ensuring reliable operation in electrically challenging environments. The removable screw terminal block simplifies installation, maintenance, and field wiring modifications.
The TWDDDO8TT delivers 8 discrete transistor outputs rated at 24V DC with sourcing logic. Each channel supports 0.3A continuous current, while the single common point handles up to 2.9A total. The output voltage operates within a range of 20.4V to 28.8V DC, accommodating typical industrial power supply variations. At state 1, the residual voltage remains ≤ 0.2V, ensuring efficient power delivery to connected loads.
This module achieves rapid switching with a 300 µs response time for state 1 transitions and 450 µs for state 0 transitions. Consequently, the TWDDDO8TT performs exceptionally well in high-speed applications such as packaging lines and assembly operations. The fast response enables precise timing control for critical processes.
The TWDDDO8TT features integrated overload and short-circuit protection on all channels. This safeguards both the module and field devices from damaging electrical faults. Additionally, photocoupler insulation provides 1500 Vrms isolation between channels and internal logic for one minute, effectively preventing ground loops and protecting the controller. This dual-protection approach significantly enhances system reliability.
The TWDDDO8TT consumes only 5 mA at 5V DC when all outputs are off, and 10 mA at 5V DC when all outputs are on. At 24V DC, it draws 20 mA with all channels activated. This low power consumption minimizes load on the system power supply, making it an energy-efficient choice for dense I/O configurations.
This module drives inductive loads up to 2000 mH, accommodating relay coils, contactors, and small solenoid valves. Furthermore, it supports tungsten loads up to 16W, suitable for incandescent indicator lamp applications. Always verify that your specific loads fall within these ratings to ensure long-term operational reliability.
Weighing just 0.085 kg, the TWDDDO8TT maintains a compact form factor suitable for space-constrained control cabinets. Its lightweight construction simplifies installation and reduces stress on mounting hardware. The removable screw terminal block organizes field wiring and simplifies troubleshooting and maintenance.
The operating temperature range spans 0°C to 55°C, covering most indoor industrial environments. For storage, the module tolerates temperatures from -25°C to 70°C, accommodating various warehousing conditions. The IP20 protection rating provides basic defense against solid objects larger than 12 mm, suitable for standard control cabinet installations.
This module carries UL and CSA certifications, confirming compliance with North American safety standards. Additionally, it features CE marking and meets environmental compliance requirements. These certifications streamline system approvals for global projects.
First, confirm that your Twido base station has an available slot for the TWDDDO8TT. Next, ensure all power sources are disconnected before installation to prevent electrical hazards. Align the module with the guide rails and push firmly until it clicks into position. Finally, engage the retaining clips to secure the module against vibration and accidental removal.
Connect field devices to the removable screw terminal block using appropriate wires. The terminal block features clear labeling for each output channel: OUT_DIS#0 through OUT_DIS#7, along with COM_POS for the common positive connection. For optimal signal integrity, separate output wiring from high-power AC conductors to minimize electromagnetic interference. Additionally, use ferrules on stranded wires to ensure reliable terminations. Connect an appropriate fuse for the load, not to exceed 4 A.
After physical installation, configure the TWDDDO8TT within your Twido programming environment. Assign suitable output addresses and establish default states for CPU stop conditions. Test each of the 8 channels individually using diagnostic functions to verify correct wiring and operation before full system commissioning. Note that this module can be attached to any Twido controller except the Compact 10 I/O and 16 I/O models.

1. Is the TWDDDO8TT compatible with all Twido controllers?
Yes, the TWDDDO8TT works with all Twido programmable controllers that support discrete output modules. However, it cannot attach to Compact 10 I/O and 16 I/O controller models. Always check your base station's capacity to ensure compatibility.
2. Can I connect AC loads to this module?
No, this module provides DC outputs only. For AC load control, consider using a relay output module like the TWDDRA8RT, which offers 8 relay outputs for AC/DC applications.
3. What happens if I exceed the 0.3A per channel rating?
The module's short-circuit and overload protection will activate, shutting down the affected channel to prevent damage. After resolving the fault, recycle power or reset the output to resume normal operation.
4. How do I wire the common point for the TWDDDO8TT?
This module has a single common point (COM_POS) serving all 8 outputs. Connect the DC power supply's positive terminal to COM_POS. Each output then sources positive voltage to the load, with the load's negative side connected to the power supply return.
5. What type of terminal block does the TWDDDO8TT use?
The TWDDDO8TT features a removable screw terminal block for all field wiring connections. This design simplifies installation and allows convenient module replacement without rewiring.
