Parker SIM8-OUT-NPN Digital Sinking Output Relay Card

Parker SIM8-OUT-NPN Digital Sinking Output Relay Card for EVM32 Baseboard is a Parker relay interface module designed to connect to the EVM32 baseboard. It provides digital sinking outputs (NPN) to drive relays from the baseboard’s control signals, enabling straightforward interfacing between a development system and external loads. Users connect control signals from a microcontroller or development board to the SIM8-OUT-NPN to energize the relay contacts, which then switch higher‑voltage or higher‑current circuits connected to the card. Designed for use with the EVM32 baseboard, this card fits into Parker’s development ecosystem to support hardware-in-the-loop testing, prototyping, and educational exercises that require reliable relay actuation controlled by digital logic.
