The 1756-IB16 is a 16-point 12/24V DC isolated digital input module from the ControlLogix family manufactured by Allen-Bradley (Rockwell Automation). This module has the following features:
Contains 16 independently isolated input channels that can accept input signal voltage ranges from 10-30V DC, with a nominal value of 24V DC.
It is commonly used to connect discrete devices such as buttons, switches, auxiliary contacts, and other devices that provide binary or switching signal states.
The module is a single-slot design and can be installed into any 1756 ControlLogix chassis, except for slots dedicated to the ControlLogix processor or communication adapter.
Suitable for local I/O configurations as well as remote or distributed I/O architectures.
The input channel has an inherent signal conversion delay, the conversion delay from off to on is up to 1 ms hardware delay plus user optional 0-2 ms filter time; The conversion delay from on to off consists of a maximum hardware delay of 4 ms plus a user selectable filter time of 0-18 ms.
Current consumption is 100 mA at 5.1V DC and 3 mA at 24V DC, with a total backplane power requirement of 0.58 watts.
Removable patch boards (RTB) such as 1756-TBCH and 1756-TBS6H are required to simplify module replacement or migration.
The operating voltage range is 10 to 30V DC, the nominal input voltage is 24V DC, the maximum power consumption is 5 W at 60 degrees Celsius, and the heat dissipation is 17.05 BTU/ hour.
