2085-IQ16 New Sealed 2085IQ16 Micro800 16 Point Digital Input Module
PRODUCT DETAILS
2085-IQ16 — Micro800 16-Point 24V DC Input Expansion Module
The 2085-IQ16 is a 16-point digital input expansion module for the Micro800 2085-series I/O expansion bus, compatible with Micro820 and Micro830 controllers. It accepts standard 24V DC sourcing or sinking field devices and adds substantial input capacity in a single expansion slot for applications where the controller's onboard inputs are already fully allocated.

Adding Input Capacity Where It's Needed
Micro800 controllers ship with a fixed onboard input count, which works fine until a machine's sensor population grows beyond it — additional part-detection sensors, more limit switches, or an expanded interlock scheme can quickly consume every onboard point. The 2085-IQ16 adds 16 more inputs in one expansion slot rather than forcing a controller upgrade, keeping the existing program and wiring largely intact while accommodating the additional sensor count.
Since it accepts both sourcing and sinking devices, the module doesn't lock the application into one sensor convention — useful when field devices come from different vendors or when the exact sensor mix isn't finalized at the panel design stage.
FAQ
Q: How many 2085-IQ16 modules can be added to one Micro830 controller?
The 2085 expansion bus supports a defined maximum number of expansion modules per controller, which varies by Micro830 model — verify the specific controller's expansion limit before planning a system with multiple input expansion modules.
Q: Does this module require its own end cap if installed at the end of the expansion chain?
Yes. Any 2085 module at the end of the expansion bus requires the 2085-ECR end cap on its right-side connector to properly terminate the bus, regardless of the module type.
Q: Can sourcing and sinking devices be mixed across the 16 inputs?
This depends on how the input commons are wired — devices sharing a common group must use a consistent convention. Mixing types typically requires assigning sourcing and sinking devices to separate input groups rather than freely mixing within the same common.
Q: Is the 2085 expansion bus hot-swappable for this module?
No. The 2085 bus does not support hot insertion or removal — de-energize the system before adding, removing, or replacing this module.
