Application
- 2 DC-OK outputs for monitoring of device functions.
- Floating signal contacts and an active DC-OK signal are available.
- The DC-OK LED enables visual evaluation of the function locally in the process.
Technical characteristics
- The 85...264 VAC connection is made by using pin no. 31, 32 and 33
- The 24 VDC connection is made using the “+” and “-“ connections.
- 22 VDC ±2 VDC is applied on “DC-OK” - pin 15, 20 mA max. This signal output is referenced to –Vout (gnd.) and signals when the output voltage drops between 18 and 22 VDC.
- Maximum 5 devices of the same type can be connected in parallel to enable increased output power.
- The DC-OK LED is a two colour LED which indicates the status of the output and enables visual evaluation of the function locally in the control cabinet.
- DC-OK LED green – normal operation. DC-OK LED red – output failure if input mains is still present.
