Parker EVM32-II Modular Expansion Base Plate

6.3 High reliability switch application

When the load requires frequent switching (such as tens of times per second) or operates in flammable and explosive environments, SIM8-OUT-SSR solid-state relay board should be selected. Solid state relays have no mechanical contacts, do not generate sparks, and have a fast response speed and extremely long lifespan. For example, driving the cutter after color code detection in packaging machinery, or in LED light flicker testing, SSR output is an ideal choice.

6.4 High power load control

For direct control of high current AC contactors, motor brakes, or electromagnetic suction cups, it is recommended to use SIM8-OUT-HCR high current relay boards. Its contact capacity is much larger than that of ordinary solid-state relays, and it has a clear disconnect gap, making it safer. Although the switching life of mechanical relays is limited, their reliability and overload capacity advantages are obvious in situations where the switching frequency is not high (such as a few times per minute).

Brief explanation of installation steps

Although detailed steps need to refer to the 6K supplement manual, the back of the document provides basic instructions for inserting the SIM board into the substrate. The general process is as follows:

Ensure that all power supplies to the EVM32 substrate have been disconnected.

Wear an anti-static wristband and place the substrate on an anti-static pad.

Remove the ventilation cover plate from the substrate.

Insert the SIM board vertically into the corresponding slot according to the slot direction, ensuring that the connector is fully engaged.

Repeat the above steps to install all required SIM boards.

Use the accompanying label paper to record the SIM board type and I/O address for each slot, and then stick it on the outside of the cover plate.

Reinstall the ventilation cover.

Connect the cable to the 6K controller or the previous stage EVM32 unit.

Connect the power and confirm that each SIM board is correctly recognized through the software of the 6K controller.
