0-10V Analogue Interface with 24V relay

This interface is designed to manage the signals on a 0-10V scale, and the instructions / status on 24V relay interface.

The power supplies can be remotely controlled through a 0-10V analogue interface. The interface consists in a single DB-25 connector, located on the rear panel of the power supply. With this option, the instructions and statuses are managed through a 24V relays.

The remote control cable must be shielded, and we recommend to install a length shorter than 3m.
