Product Summary
The 1794-IA16 Flex I/O AC input module provides sixteen non-isolated channels for 120VAC discrete signals. This module interfaces sensors and pilot devices directly to your control system. It requires a compatible terminal base for field wiring and installation.
Theme A: Product Procurement & Buyer Guide
Understanding Your Input Requirements
The 1794-IA16 module operates within a specific voltage window. You must supply an On-state voltage between 74VAC and 132VAC. The nominal input voltage is 120VAC. This module reads a minimum On-state current of 5.49 mA. It detects an Off-state at a voltage below 20VAC.
Selecting the Correct Terminal Base
This module contains only the I/O circuitry. You need a terminal base for all field wiring connections. The 1794-IA16 works with several bases. These include the 1794-TB3, 1794-TB3S, and 1794-TBN. You can also use the 1794-TB3K, 1794-TB3SK, and 1794-TBNK models.
Power and Bus Current Calculation
The 1794-IA16 draws its power from the FlexBus backplane. It requires a FlexBus current of 20 mA at 5VDC. You must account for this draw when sizing your system power supply. The module dissipates a maximum of 6.4 Watts at 132VAC.
Matching Communication Adapters
This input module works with several Flex I/O communication adapters. You can integrate it with ControlNet adapters like the 1794-ACN or 1794-ACNR. It also supports Ethernet adapters such as the 1794-AENT and 1794-AENTR. The 1794-ASB remote I/O adapter is another option.
Environmental Fit and Installation
The 1794-IA16 operates in temperatures from 0 to 55 degrees Celsius. It can withstand 5g of vibration at 10 to 500 Hz. The module mounts easily on a standard DIN rail. Its open-style enclosure requires installation inside a suitable cabinet.
