FAQ

Q: What voltage levels does this IOTA support?
A> The CC-TDI110 supports 120 VAC, 125 VDC, and 240 VAC nominal input voltages.

Q: Is this IOTA redundant?
A> No, CC-TDI110 is a non-redundant 9-inch IOTA. For redundant configurations, use CC-TDI220 or CC-TDI230.

Q: What electronics module pairs with this IOTA?
A> The CC-TDI110 is designed for use with the CC-PDIH01 Digital Input High-Voltage electronics module.

Installation Guidelines

1. Mount the CC-TDI110 IOTA on a DIN rail or panel in a suitably rated enclosure.
2. Install the CC-PDIH01 electronics module onto the IOTA.
3. Connect high-voltage field wiring (120 VAC / 125 VDC / 240 VAC) to the terminal blocks.
4. Verify proper grounding and shielding for high-voltage signal integrity.

Selection Tips

• Order CC-TDI110 for non-redundant high-voltage digital input (120 VAC / 125 VDC / 240 VAC) applications.
• For redundant high-voltage DI, select CC-TDI220 or CC-TDI230.
• Always pair with CC-PDIH01 electronics module for complete functionality.
