BMS Digital card

Description of the BMS Digital card for HIL Connect hardware

Note: For more information on how to configure your card in Typhoon HIL Control Center, please refer to the BMS Digital Card parametrization documentation.

The BMS Digital card is designed to offer digital inputs and outputs for versatile applications. It includes 16 optically isolated voltage inputs (connected to 16 HIL DI channels) and 16 relay outputs (controlled by 16 HIL DO channels). It features galvanical isolation on all channels independently up to 200 V.
