The Allen-Bradley 1794-IV32 is a 32-point, 24V DC sourcing input module, part of the FLEX I/O platform.

What is the difference between sourcing and sinking?

The 1794-IV32 is a sourcing input module, meaning it supplies voltage to the input device, which then connects to common. If you need to sink current, you would use a different module like the 1794-IB32

What status indicators are available?

The module features 32 yellow status LEDs located on the front panel, providing a dedicated indicator for each input channel to show its ON/OFF state

What communication networks can it use?

The 1794-IV32 communicates with a controller via a FLEX I/O communication adapter. Supported networks include EtherNet/IP, ControlNet, and DeviceNet.

What is the operating voltage range?

While nominally 24V DC, sourcing modules in this series typically have an ON-state voltage range of approximately 19.2V to 31.2V DC.

The Allen-Bradley 1794-IV32 is a high-performance digital input module belonging to the industry-leading FLEX I/O family. This module is engineered to provide a cost-effective and space-efficient solution for industrial automation systems requiring a high volume of 24V DC discrete inputs. By packing 32 sourcing-style inputs into a modular housing, the 1794-IV32 drastically reduces the complexity and size of control cabinets in applications like packaging, material handling, and automotive assembly.

The 1794-IV32 Allen Bradley INPUT MODULE may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The Allen-Bradley 1794-IV32 is part of the Flex I/O platform, typically used in implementing distributed I/O topology. This module is specifically a high-density discrete input module that features Thirty-Two (32) current sourcing input channels. This module is designed to accept nominal input signal voltage of 24 VDC, enabling integration of discrete input signals such as switches, auxiliary contacts, sensors, and similarly binary operating devices. The 1794-IV32 is installed along with a Flex I/O assembly with a Flex I/O communication adapter as the header module. The data within the 1794-IV32’s local memory is transferred via the FlexI/O bus which is then forwarded to the host controller through a communication highway. The 1794-IV32 has a FlexBus current draw of 40 mA at 5 VDC. It has a minimum On-state voltage of 19.2 VDC while the maximum On-state voltage is 31.2 VDC. Additionally, the minimum On-state current is 2.0 mA while the maximum is 6.0 mA. Configurable filter times are available to this module specifically, 0.25 ms; 0.5 ms; 1 ms; 2 ms; 4 ms; 8 ms; 16 ms, and 32 ms. Filter times can be used to eliminate false activation due to debouncing or noises. The default filter time is 0.25 ms.

The Allen-Bradley 1794-IV32 and 1794-OV32 are high-density 32-point digital I/O modules within the FLEX I/O platform, designed for distributed I/O applications, particularly in tight spaces requiring high-density mapping. They are typically used with Allen-Bradley ControlLogix or CompactLogix controllers via adapters like the 1794-AENT/AENTR.

FLEX I/O XT (1794-IV32XT / 1794-OV32XT): These are the "Extreme Environment" counterparts. They offer the same functionality as the 1794-IV32/OV32 but are built for harsh conditions (higher/lower temperatures, conformal coating).
