1756-OB16S Allen Bradley ControlLogix Module

The 1756-OB16S Standard Chassis by Allen-Bradley is an I/O chassis in the 1756 ControlLogix System with a maximum capacity of 10 slots. It has a horizontal specialized panel mounting style and the backplane module slot allows for high-speed communication between the modules installed on it.

The 1756-OB16S has a backplane electrical rating of 1.5 A/1.5A backplane current between the chassis and slots (chassis/slot) at 1.2V, one of 4/4A at 3.3V, and one of up to 2.8 A/2.8 A at 24V. It has a 5-Watt power dissipation (6.1 BTU/hr Thermal dissipation equivalent), and it has a maximum operational power consumption of 1.8W. It is designated with a T5 environmental temperature code (North America), and with a T6 IEC code (European Union).
