2085-IQ16 | Allen-Bradley 16 Point Digital Input Module

The Allen-Bradley 2085-IQ16 is a Micro850 discrete digital I/O expansion module manufactured by Rockwell Automation that features 12-24V DC sink/source inputs with 16 channels. It requires a 24V DC power supply and has an IP20 enclosure rating. It has a total power dissipation of 4.5 W, a maximum input impedance of 3.9 kΩ, and a maximum bus current draw of 170 mA at 5V DC. The operating voltage ranges of the 2085-IQ16 module are 10-30V DC and 21.6-26.4V AC, with both ranges in Class 2. The maximum off-state voltage of this module is 5V DC, while its maximum off-state current is 1.5 mA. When in the on-state, the 2085-IQ16 module has a current that ranges from a minimum of 1.8 mA at 10V DC to a maximum of 8 mA at 30V DC, with a nominal current of 6 mA at 24V DC. The continuous isolation voltage of this module is 50V and it is a reinforced insulation type from channel-to-system and it has been type-tested at 720V DC for 60 s.

Expansion I/O modules such as the 2085-IQ16 module extend the capabilities and functions of Micro850 controllers. They come with 16 LED status indicators and a removable terminal block (RTB). It is important that the 2085-IQ16 module be removed or inserted only when the backplane power is turned off to avoid an electrical arc that can result in an explosion. This module is also sensitive to electrostatic discharge or ESD. The approximate dimensions of this module are 1.75 x 3.54 x 3.42 inches and it weighs 220 g or 7.76 oz.
