About 1794-IB32

The Allen-Bradley 1794-IB32 is a FLEX 24 Volts DC digital I/O module. It comes with 32 sink inputs available. These inputs come in 2 groups of 16 non-isolated inputs and 32 yellow status indicators. This module is attached to an Allen-Bradley terminal base unit and it can be the 1794-TB32S, 1794-TB32, 1794-TB62EXDX15, or the 1794-TB62DS. It also comes with 32 yellow status indicators. The 1794-IB32 can be removed even when the system is powered on because there is no direct wiring involved between the module and the terminal base. This makes it possible to change modules directly without disrupting the entire system by powering it off.

It has a nominal on-state voltage of 24 Volts DC and the on-state voltage ranges from a minimum of 19.2 Volts DC to a maximum of 31.2 Volts DC. Its maximum off-state voltage is 5 Volts DC and its maximum off-state current is 1.5 mA. The 1794-IB32's nominal on-state current is 4.1 mA at 24 Volts DC and it ranges from 2 mA minimum to 6 mA maximum. The FlexBus current of this module is 30 mA at 5 Volts DC.

While there is no isolation between individual channels, the 1794-IB32 has an isolation voltage of 50 Volts which is continuous between the system and field side. It has a maximum thermal dissipation of 20.47 BTU/hour at 31.2 Volts DC and a maximum power dissipation of 6 W at 31.2 Volts DC. The operating temperature of the module is 0 to 55 degrees Celsius while its storage temperature is -40 to 85 degrees Celsius. It has an operating vibration of 5 g at 10 to 500 Hertz, an operating shock of 30 g, and a non-operating shock of 50 g. The 1794-IB32 also has a relative humidity of 5 to 95% that is non-condensing.
