The Allen-Bradley 1756-OF8IHK is a versatile ControlLogix HART I/O Module, designed for robust performance under rigorous conditions, as evidenced by its durability testing per ASTM B845-97 and IEC 60068-2-60 standards. This module operates with a DC input voltage rating of ±24 Volts DC featuring overvoltage protection and supports HART 6 and 7 protocols with an impressive 8 isolated differential outputs. With 15 bits over 24 mA resolution and certified by C-UL-us, CE, RCM, Ex, KC, and EAC, this open-style module with a conformal coating is perfectly suited for integration within a ControlLogix system. It can be utilized in local or networked chassis setups via ControlNet or EtherNet/IP, requiring either a removable terminal block or a Bulletin 1492 wiring interface module for field-side connections.
