Allen-Bradley 1794-IB32 Flex I/O Input Module

Description

The Allen-Bradley 1794-IB32 Flex I/O Input Module is a distributed DC digital input component belonging to the Flex I/O product series, designed to integrate field devices into automated control systems. As a 32-channel current sinking input module, it supports connection to up to 32 DC input devices, including buttons, limit switches, proximity sensors, float switches, process switches, relay contacts, and contactor auxiliary contacts. Each channel operates with a nominal signal level of 24VDC, with a minimum on-voltage of 19.2VDC and a maximum on-voltage of 31.2VDC.

Engineered for high-density input applications, the module features individual LED indicators for each of its 32 channels, which activate when a signal is received and turn off when no signal is present, enabling quick identification of active channels and verification of device operation. It is compatible with Flex I/O communication adapters such as Ethernet and ControlNet, with no limit on installation instances when following proper setup guidelines. The module works with terminal bases including 1794-TB32, 1794-TB32S, 1794-TB62DS, and 1794-TB62EXD4X15, supporting hot insertion and removal for flexible maintenance. Its environmental specifications include an operating temperature range of 0 to 55 degrees Celsius, vibration resistance up to 500G, and shock resistance of 30/50G, ensuring reliable performance in industrial settings.
