OP8930 Pin Assignment

Owned by Sylvain Ménard
Last updated: Apr 19, 2023


Before designing cables, OPAL-RT recommends using these guidelines: Simulator EMC cable recommendations.

J1/J2 HDB44 Connector Pinout

As explained in OP8930 Hardware Interface, both HDB44 connectors J1 and J2 share the same pin-out.  The 16 analog I/O signals are routed to both J1 and J2 connectors. This allows, for example, splitting the input and output signals into two different cables.
