The 1756-OA8D ControlLogix Output Module from Allen-Bradley is a versatile eight-point diagnostic output module designed for seamless integration into any slot of the 1756 ControlLogix Chassis. This module supports output voltages between 74 and 132V AC and offers robust performance with a maximum surge current of 8A for 43ms, recurring every 2 seconds at 30 °C. With a power dissipation of 53W and a thermal dissipation of 18.0 BTU/hr, it excels in efficient energy management. The rugged unit handles a maximum current of 1A per output point, with a total capacity of 8A at 30 °C, which linearly de-rates with increasing temperature. Its isolation capability reaches 125V continuous and has been tested up to 1200V AC for 2 seconds, ensuring safety and reliability in diverse applications. Additionally, the module's single-slot form factor and customizable keying on its Removable Terminal Block (RTB) offer installation flexibility, while its operational range between 0-60 °C accommodates various environmental conditions. Weighing just 1 kg, this module efficiently balances functionality with a compact design.
