 Product Description

Input Module, 120VAC, 16  Inputs 1794 FLEX I/O

 Warranty Information

All Surplus and Refurbished products come with a 1-Year Automation Webstore Warranty.

 Product Overview

The 1794-IA16 is a Flex IO module that is used to implement distributed IO applications. This module has Sixteen (16) non-isolated Discrete AC input modules which can be used to interface signaling device or instruments from the field. This module is a DIN rail mounted hardware that may be partnered to any 1794 Flex IO adapter module.

The 1794 IA16 requires a terminals base for input wiring termination. Terminal bases with part number 1794-TB3, 1794-TB3S or 1794-TBN, 1794-TB3K, 1794-TB3SK and 1794-TBNK may be used with the module. Terminal base also allows daisy-chaining of power to the next adjacent module and houses the locking mechanism to maintain attachment to 1794-IA16.

This module operates with a voltage range of 74-132VAC, with nominal Voltage of 120VAC. It has a minimum On-state voltage of 74VAC and maximum of 132VAC while the maximum OFF-state voltage is 20VAC. To energize the internal circuitry of this module, it requires a Flexbus current of 20 mA @ 5V DC. It has maximum Power dissipation of 6.4 W @ 132V AC and maximum thermal dissipation of 21.8 BTU/hr @ 132V AC.

Most Flex IO adapter support installation of Eight (8) modules to its local FlexBus. This means a single adapter may have 8 1794-IA16. This may be implemented to allow segmentation of I/O channels providing design flexibility and practicality.

This module has physical dimension of 94 x 94 x 69 mm (3.7 x 3.7 x 2.7 in.). Ensure that the installation area or maintain enclosure temperature within the required Operating Temperature range of 0…55 °C (32…131 °F), shock rating of 30g and Vibration rating of 5 g @ 10...500 Hz. Ensure adequate protection for mechanical, electrical and environmental interferences is installed to maximize the module’s designed lifespan.
VIIIVThe 1794-IA16 is a Flex IO Sixteen (16) channel AC input module. This module can be fitted with any 1794 Flex IO adapters to implement distributed I/O application.
