Systems and methods for coupling input/output devices

A component of an input/output (I/O) device, the component comprising:

• a first connector configured to engage with a second connector of an additional component of the I/O device;
• and
• an ejection device configured to eject the additional component from the component by pushing the second connector away from the first connector, wherein the ejection device comprises:
• an activation portion extending outside of the component and configured to be physically actuated;
• and
• an ejector portion configured to contact any apply force against the additional component as a mechanical response to physical actuation of the activation portion.

An input/output (I/O) device for an automation control system, the I/O device comprising:

• a base portion comprising at least a first mating feature of the base portion and a second mating feature of the base portion;
• an I/O module configured to physically and communicatively couple with the base portion via coupling of a mating feature of the I/O module with the first mating feature of the base portion, wherein the I/O module comprises I/O communication circuitry;
• a terminal block configured to physically and communicatively connect to the base portion via coupling of a mating feature of the terminal block with the second mating feature of the base portion;
• and
• a locking mechanism configured to couple together the I/O module and the terminal block when in a closed orientation, wherein the locking mechanism comprises a conducting portion configured to communicatively couple circuitry in the I/O module with circuitry in the terminal block when the locking mechanism is in the closed orientation.
