  • Page 22: Outputs

    The power supply status relay has a set of normally closed contacts and energizes when operating power is applied to the BE1-47N. If relay operating power is lost or either side of the power supply output (+12 Vdc or –12 Vdc) fails, the power supply status relay de-energizes and opens the power supply status output contacts.
