Properties:

• A redundant power supply can be set up using two power-feed units and two separate power supplies.
• The device can be used in safe (non-explosive-risk) areas or in Zone 2 or Division 2.
• Two green LEDs indicate the operating status of the power supply and the backup power supply.
• The power-feed unit ACT20-FEED-IN-PRO-S detects errors on each of the devices mounted on the Weidmueller CH20M DIN rail and sends a collective message to an external controller via the internal status relay.
• A red LED indicates a fault.
• When these circumstances are satisfied, the status relay is turned on.
• The connection terminals 51 and 52 have a supply voltage.
• The terminals 53 and 54 are home to the backup supply voltage.
• Insert the included jumper between terminals 52 and 53 if the backup power supply is not needed.
• There are no errors reported by the devices mounted on the Weidmueller DIN rail.
