General Description
Delta’s CliQ II redundancy modules offer a variable input and output voltage from 22Vdc to 60Vdc. The DRR-20☐ and DRR-40☐ can
operate over a wide temperature range of -40°C to -80°C. The state-of-the-art design is made to withstand harsh industrial
environments. The rugged, compact aluminium case is shock and vibration resistant according to IEC 60068-2 standard. Due to the
wide input and output voltage range from 22Vdc to 60Vdc, the redundancy modules are able to support power supply in parallel
operation. These modules also have an alarm relay contact as an indicator.
