The 1794-IB32 is an Allen-Bradley module that belongs to the Flex I/O product family of distributed I/O components. The module is an input interface device that allows field instruments and electrical equipment such as push button devices, limit switches, proximity sensors, float switches, process switches, relay contacts and contactor auxiliary contacts to be integrated into any automatic control system or process.

The 1794-IB32 can accommodate up to 32 DC input devices. It is a 32-channel current sinking module with a minimum on-state voltage range of 192 per channel. The maximum range is 31.2VDC and the nominal signal level is 24VDC.

The 1794-IB32 is capable of installing Flex I/O communication adapters such as Ethernet, ControlNet, Remote I/O, and others. As long as Flex I/O installation requirements are met, there is no limit to the number of installation instances supported by this module.

1794-IB32 is a high-density input channel. Each of the 32 channels is equipped with an LED indicator to monitor the activity of each channel. This helps to more quickly identify active channels and verify correctly working input devices. These LED lights simply light up when a signal is received and turn off when the signal is not present.

The module is connected to a Flex I/O terminal dock. The terminal base provides input and power terminals and DIN rail mounting slots. Terminal bases compatible with this high-density input module are 1794-TB32, 1794-TB32S, 1794-TB62DS, and 1794-TB62EXD4X15. The terminal block also allows the module to be removed and inserted under the power supply.

The 1794-IB32 has a nominal on-voltage of 24v DC, with a minimum on-voltage range of 19.2 v DC and a maximum on-voltage range of 31.2v DC. The maximum turn-off voltage is 5 volts DC and the maximum turn-off current is 1.5 MA. The 1794-IB32 has a nominal on-state current of 4.1 mA, 24 volts DC, ranging from a minimum of 2 mA to a maximum of 6 mA. The FlexBus current of the module is 30 MA at 5 volts DC. Although there is no isolation between the individual channels, the 1794-IB32 has a continuous isolation voltage of 50 volts between the system and the field side. The maximum heat dissipation is 20.47 BTU/ hour at 31.2 volts DC and the maximum power consumption is 6 watts at 31.2 volts DC. The operating temperature of the module ranges from 0 ° C to 55 ° C and the storage temperature ranges from -40 ° C to 85 ° C. The 1794-IB32 has a relative humidity range of 5% to 95%, no condensation, operating frequency of 10 to 500 Hz, operating vibration of 5g, operating shock of 30g, and non-operating shock of 50g.
