MIO is an accessory of the Picolo Tetra modular architecture serving both the internal and external configurations. MIO brings flexible isolated logic inputs and outputs.

MIO offers four opto-isolated input and four reed relay output lines. They are natively supported by the MultiCam driver. Each input line is interrupt-capable, with independent edge sensitivity control. The status of the lines is monitored by eight dedicated LEDs.

The fourth relay output can be configured as an alarm, a watchdog or a standard output. In alarm mode, as long as the application is not started, the relay remains open. Once operating correctly, the application closes the relay. In watchdog mode, as long as the application is not started, the relay remains open. Once operating correctly, the application resets regularly the watchdog timer. If a watchdog time out occurs, the relay is closed.

Each line is available as a pair of electrical wires on the removable sixteen terminal block.

A VEB (Video Expansion Bracket) adds four video connections to a Picolo Tetra or a Picolo Alert. The video inputs are selectable color or monochrome composite inputs, terminated with removable 75 Ω resistors. This module can be used as input or output, depending of the selected VEB LINK connector (video in or video out).

When the VEBs are used to add video inputs, up to 3 VEBs can be linked up with the same Picolo card.

With the Picolo Tetra, a VEB can be used for video output of digitalized images
