A-8 Specifications and Dimensions
Internal Shunt Resistor
The 1394C-SJT05-D and -SJT10-D system modules include an internal
shunt resistor. Shunt specifications are shown in the table below.
Note: When the shunt resistor is active, some additional power will be
dissipated at the system module. Its maximum dissipation is
200W. Most applications will use less than 10% of this capacity.
General Specifications The following sections provide environmental, AC line filter, external
shunt module, resistive brake module, maximum feedback cable
lengths, and dedicated discrete I/O specifications for the 1394 SERCOS
interface system.
Environmental Specifications
