PRODUCT DETAILS
2085-OV16 — Compact Controller Expansion 16-Point Sinking Output Module
The 2085-OV16 is a 16-point sinking (NPN) digital output expansion module for compact controllers with available expansion bus capacity, switching 12/24V DC field devices. It mounts on the same expansion bus as digital input and analog modules in its family, and pairs directly with its sourcing counterpart in the same series for installations needing either output convention.

Sinking Outputs as the Other Half of a Pair
This module's sourcing counterpart in the same expansion family supplies 24V to the load directly, while the 2085-OV16 instead provides the return path to common — pairing with field devices that already have their own positive supply and simply need a switched path to ground. The choice between the two comes down entirely to how the connected actuators, indicators, or relay coils are wired and what convention the rest of the panel's field devices already follow.
The removable terminal block design is consistent with the rest of the platform's expansion I/O family — a faulted output point can be diagnosed using the 16 individual channel LEDs, and the module itself can be swapped without disturbing the field wiring landed on the terminal block, which stays with the DIN rail mounting position rather than the module body.
FAQ
Q: What's the difference between this module and the sourcing variant in the same family?
The sourcing module supplies positive voltage to the load; this sinking module provides the return path to common instead. Select based on how the connected field devices are wired — sourcing field devices pair with this sinking output module.
Q: Does this module require its own field power supply?
Yes. A 24V DC Class 2 field power supply is required for the output circuits — this is separate from the controller's own backplane power, which the module draws only a small bus current from.
Q: Can this expansion module be used with any controller in the compact family?
Expansion modules in this series are compatible with specific controller models in the family that include expansion bus capability — verify the target controller supports expansion I/O before specifying this module, since not every model in the broader family includes that capability.
Q: How is a faulted output point identified?
Each of the 16 channels has its own status LED — a quick visual check of the LED pattern against the expected output state typically narrows down a wiring or load issue to the specific channel without needing to trace each circuit individually.
