Lock / Brake Output
This output is used to power an electrical lock or a motor brake release. The factory default for the lock/
brake release is on output 1. Output 1 is a voltage-free relay contact with common and normally open
contacts. Having it voltage-free allows you to connect either 12VDC/AC, 24VDC/AC or 240VAC to the
common. The normally open contact drives the lock/brake. See diagram below:
