The Allen-Bradley 1756-IG16 is a high-performance TTL input module designed for seamless integration with the ControlLogix 1756 chassis, requiring either the 1756-TBNH or 1756-TBSH removable terminal block housing for installation. This module operates on a 5 Volts DC TTL source where lower voltage indicates a true state, supporting an operating voltage range from 4.5 to 5.5 Volts DC with a low-to-high transition delay of up to 700 microseconds, depending on user-selected filter times. Built for efficient performance, it features a nominal input current of 3.7 milliamps at 5 Volts DC, with a backplane current draw of 110 milliamps at 5.1 Volts DC and a maximum power dissipation of 1.4 Watts at 60 degrees Celsius.
