The Allen-Bradley 1756-OA16I is a robust sixteen-channel discrete output module within the ControlLogix series, engineered for high-performance applications with an operational voltage range from 75 to 265 VAC at frequencies between 47-63 Hz. This module facilitates precise electrical load management through compatible Removable Terminal Blocks (RTB), specifically models 1756-TBCH and 1756-TBS6H, and fits seamlessly into any 1756 chassis or remote I/O rack via a 1756 Communication adapter. Supporting various configuration modes for fault and output states, the 1756-OA16I ensures reliable performance with a backplane power draw of 1.59 Watts and efficient thermal management capacities while maintaining isolation voltage standards of 250V.
