Product Summary
The 1794-IB16D Flex I/O module delivers precise 24V DC digital input monitoring. Its advanced diagnostics detect faults like open wires or short circuits instantly. This reduces downtime and simplifies troubleshooting for industrial control systems.
Why Choose the 1794-IB16D for Your System
This module provides sixteen sinking current inputs for your field devices. It operates with a nominal on-state voltage of 24V DC. The maximum on-state current is just 1.5mA, which ensures low power consumption.
The 1794-IB16D unit includes a powerful diagnostic feature set. It identifies disconnected wires and reversed power supply connections. This capability allows engineers to fix wiring errors very quickly. The module also detects open input circuits from field devices. You can reduce commissioning time with this proactive fault detection.
Step-by-Step Installation Guide for the 1794-IB16D
First, mount the module on a compatible terminal base unit. You must use either a 1794-TB32 or a 1794-TB32S base. Set the keyswitch on the terminal base to Position 4 before seating the module. Then push the Flexbus connector to the left to connect. This connects the module to the adjacent terminal base unit.
Next, wire your 24V DC sensors to the input terminals. The module accepts an on-state voltage range of 10 to 32V DC. The sensor power supply provides up to 50mA of current. You can configure the digital signal filtering time as needed. This adjustable filter improves signal integrity in noisy environments.
Key Technical Specifications for Procurement
The 1794-IB16D module draws only 30mA from the 5V DC Flexbus. Its maximum power dissipation is 8.5W at 31.2V DC. The unit offers an isolation voltage of 50V continuous for safety. Its physical dimensions are 45.7mm x 94mm x 53.3mm. The module weighs just 0.09 kilograms for easy installation.
The diagnostic indicators include 16 red status lights and 16 yellow lights. A single red module fault indicator alerts you to major issues. This visual feedback allows operators to assess status at a glance. The module fits seamlessly into the modular Flex I/O system architecture.
