The Allen-Bradley 1756-OF8IHK is a sophisticated ControlLogix HART I/O module designed with an emphasis on durability and performance, verified through ASTM and IEC test environments. Featuring 8 isolated differential outputs and a HART modem per channel, it supports both HART 6 and 7 protocols, ensuring seamless integration with 4-20 mA applications. With DC input voltage at ± 24 Volts and robust overvoltage protection, this module is well-suited for complex, high-performance systems, easily connecting to ControlLogix controllers via ControlNet or EtherNet/IP networks, requiring a removable terminal block or Bulletin 1492 wiring interface for field-side connections.
