A-B Rockwell 1794-IB32 Flex I/O DC Digital Input Module

The Allen-Bradley 1794-IB32 is a Flex I/O DC input module.

The module has thirty-two (32) current sink input channels with an input voltage range of 19.2-31.2VDC.

It is compatible with Flex I/O communication adapters and terminal blocks such as the 1794-TB32. 1794-TB32S, 1794-TB62DS, 1794-TB62EXD4X15.

About the 1794-IB32

The 1794-IB32 is an Allen-Bradley module that is part of the Flex I/O product family of distributed I/O components.

The module is an input interface device that allows field instruments and electrical devices (such as pushbutton devices, limit switches, proximity sensors,

float switches, process switches, relay contacts and contactor auxiliary contacts) into any automated control system or process.

The 1794-IB32 can accommodate up to thirty-two (32) DC input devices. It is a 32-channel current sink module.

Each channel has a *minimum* on-state voltage range of 192.VDC, **range of 31.2VDC, and a nominal signal level of 24VDC.

The 1794-IB32 can be installed with Flex I/O communication adapters such as Ethernet, control network, remote I/O and other adapters.

There is no limit to the number of installations supported by this module as long as the Flex I/O installation requirements are followed.

The 1794-IB32 is a high-density input channel. each of the 32 channels is equipped with an LED to monitor activity on each channel.

This helps to more quickly identify active channels and verify functioning input devices. These LEDs simply energize when a signal is received and turn off when no signal is present.

This module connects to the Flex I/O terminal base. The terminal base provides input and power terminals and DIN rail mounting slots.

Compatible terminal bases for use with this high density input module are the 1794-TB32. 1794-TB32S, 1794-TB62DS, and 1794-TB62EXD4X15.

The terminal bases also allow removal and insertion of the module under power.

The 1794-IB32 has a nominal on-state voltage of 24 volts DC and a range of on-state voltages from **19.2 volts DC to **31.2 volts DC.

Its **off-state voltage is 5 volts dc and **off-current is 1.5 mA. The 1794-IB32 has a nominal on-state current of 1.24 mA at 4 volts dc, ranging from *2 mA minimum to 1.5 mA maximum.

The nominal on-state current of the 1794-IB32 is 1.24 mA at 4 volts DC, ranging from *minimum 2 mA to ** 6 mA. The module's FlexBus current is 5 mA at 30 volts DC.

Although there is no isolation between channels, the 1794-IB32 is isolated at 50 volts and is continuous between the system and field sides.

It dissipates 31.2 BTU/hour at 20.47 volts DC** and 2 watts at 6.31 volts DC**.

The module's operating temperature is 0 to 55 degrees Celsius, while its storage temperature is -40 to 85 degrees Celsius. It has an operating vibration of 500 G at 5 to 10 Hz.

The 1794-IB32 has an operating vibration of 500 G at 5 to 10 Hz, an operating shock of 30 G, and a non-operating shock of 50 G. The 1794-IB32 has a non-condensing relative humidity range of 5% to 95%.
