4 to 20 mA
(T7470A)
Issue 1,
March, 06
Analog output modules provide 4 to 20 mA current outputs for
a maximum of eight user loads per module. The module's
triplicated I/O Safetybus interface ensures that no
Regent
system failure will inadvertently affect the output signal, and
that no failure in the module can affect the operation of the
Regent system or other I/O modules in the system.

The processor modules send triplicated write data commands
to the output module over the I/O Safe
tybus. The processors’
addressing data and data write commands are voted by the
module (preventing I/O Safetybus failures upstream from the
