The power supplies SD811 and SD812 (24 V output) can be used to power processor modules
and S800 I/O modules, through the processor unit and to power 24 V field circuits (optional).
The supplies have a wide input voltage range, nominally 110V-240 V without input voltage range
selection. The primary side can connect to industrial mains installation class III (IEC664).
The outputs are short circuit proof and can operate with resistive, capacitive and constant power
loads, for example, switched mode power converters.
The outputs of the supplies can be connected in parallel to increase power, 2 x SD811 or
2 x SD812, or be configured for redundant mains to increase availability, 2 x SD811 or
2 x SD812. Each supply has a power OK signal which can connect to the SA or SB inputs of the
communication interface modules or Optical Modulebus modem to monitor power status in 1:1
redundant mains configurations.
