2080-OV4 — Compact Controller 4-Point Sinking Output Plug-In Module

The 2080-OV4 is a 4-point sinking (NPN) digital output plug-in module for compact modular controllers with available plug-in slots, switching 12/24V DC field devices at up to 0.5A per point steady state. As a plug-in rather than an expansion module, it mounts directly into the controller body itself, adding a small increment of additional output capacity without consuming a position on the larger expansion I/O bus.

A Small Sinking Output Plug-In for Tight Footprint Controllers

Plug-in modules and expansion modules serve different purposes on compact modular controller platforms. Plug-ins like the 2080-OV4 fit into a small number of dedicated slots directly on the controller itself, adding a handful of points without increasing the physical footprint the way a full expansion module on the side-mounted bus would. For applications needing just a few more outputs — completing an odd-numbered point count, or adding one more control signal that didn't fit the original I/O plan — a plug-in is often the more compact and economical fix compared to a full expansion module.

The sinking (NPN) output type pairs with sourcing (PNP) field devices, where the connected device supplies voltage and this module's output provides the return path to common. This is the complementary output type to the 2080-OB4 sourcing plug-in in the same family — selecting the correct type for the connected actuators and indicators avoids a wiring mismatch at commissioning.

FAQ

Q: How many plug-in slots does a typical compact controller have for this module?

Plug-in slot count varies by controller model — smaller controllers in the family typically support one plug-in position, while larger ones may support several. Verify the specific controller model's plug-in capacity before planning the I/O layout.

Q: Can the 2080-OV4 be combined with input plug-ins on the same controller?

Yes, provided the controller has enough plug-in slots available — input, output, and combination input/output plug-ins from the same family can be mixed across the available slots as the application requires.

Q: What's the difference between this module and the 2080-OB4?

The 2080-OB4 is the sourcing (PNP) counterpart — it supplies voltage to the load rather than providing a return path. Choose based on whether the connected field devices expect a sourcing or sinking control signal.

Q: Does this plug-in module require its own external power connection?

No. It draws power directly from the controller's internal backplane — no separate field power supply is needed for the plug-in module itself, though the switched loads will still need their own appropriate power source.
