Features:
- Individual Channel Isolation
- High-Voltage DC Signal Support
- Configurable Digital Input Filters
The Allen-Bradley 1756-IH16I/A provides 16 individually isolated channels, which prevents electrical noise or ground loops from affecting other circuits. This feature ensures that each input on the Allen-Bradley 1756-IH16I/A operates independently, enhancing system reliability in complex electrical environments.
Designed for 125V DC nominal systems, the Allen-Bradley 1756-IH16I/A supports a wide operating voltage range of 90V to 146V DC. This capability allows the Allen-Bradley 1756-IH16I/A to interface directly with high-voltage DC field devices such as circuit breakers and protection relays without additional signal conditioning.
The Allen-Bradley 1756-IH16I/A features user-selectable input filter times (off-to-on and on-to-off) to eliminate the effects of contact bounce and electrical transients. By adjusting these software-configurable filters, the Allen-Bradley 1756-IH16I/A can be optimized for specific response times or noise immunity requirements.
The 1756-IH16I/A Allen-Bradley ControlLogix DC Isolated input module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
