Installation & Packaging

• Installation: Mount the DC-TFB412 module on a standard DIN rail within your control panel. Connect the 24VDC power and field wiring to the clearly marked terminal blocks. Ensure the output load does not exceed the 0.5A per point rating.
• Packaging: Each DC-TFB412 module ships individually with installation documentation. We ship via reliable carriers such as FedEx, UPS, or DHL.

FAQ

• Q: What types of devices can connect to the inputs and outputs?
  A: The 16 inputs can connect to dry contacts (switches) or solid-state devices like proximity sensors. The 16 outputs are suitable for driving relays, solenoid valves, pilot lights, and other DC loads up to 0.5A each.
• Q: What is the advantage of the compact 10x18x10 cm size?
  A> The compact dimensions of the DC-TFB412 allow for high-density installations in control cabinets where space is limited. You can fit more I/O points in a smaller footprint, optimizing panel layout.
• Q: Does this module support diagnostic status indicators?
  A> Yes, the DC-TFB412 typically includes LED status indicators for each channel (showing ON/OFF state) and for module health (power, communication). This facilitates quick troubleshooting and maintenance.
