 Product Overview

The 1794-IA8I is an Eight (8) channel individually isolated Discrete AC input module which belongs to the compact and modular Flex IO product family. Individual isolation of channels allows operation of other channel of the module even if One or more channels have become defective.

The 1794-IA8I is attached to a terminal base for operation. These are separately purchased and used with other Flex IO modules as well. The terminal base provides the locking mechanism to the Flex IO module and the attachment slot to the DIN rail mount. It also houses the I/O terminals, the power input and daisy-chaining terminal to energize an adjacent module if necessary. Compatible terminal bases for the 1794-IA8I are 1794-TBN, 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TBKD, 1794- TB3K, 1794-TB3SK, 1794-TBNK.

The module’s Flexbus current requires 30 mA @ 5V DC to energize the internal circuitry that is made of an input filter, opto-isolator, rectifiers bridge, and other important electronic circuit. It has maximum Power dissipation of 4.5 W @ 132V AC and maximum thermal dissipation of 15.3 BTU/hr @ 132V AC. This module operates with a voltage range of 65-132VAC, with nominal Voltage of 120VAC. It has a minimum On-state voltage of 65VAC and maximum of 132VAC while the maximum OFF-state voltage is 43VAC.

This module has physical dimension of 94 x 94 x 69 mm (3.7 x 3.7 x 2.7 in.). The input channel occupies 16-Bit of the controller register. The input filter may also be configured through the user program with support for Eight (8) input filter selections. OFF to ON input filtering time range is 7.5 ms to 42 ms. For ON to OFF input filtering range of 26.5 ms, to 60.5 ms.

It has 8 Yellow status indictors to indicate the field instrument state such as wire continuity and others. This module has an open style enclosure rating however, always 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-IA8I is a Flex IO Eight (8) channel individually isolated AC input module. This module can be fitted with any 1794 Flex IO adapters to implement distributed I/O application.
