Application
Simplex Configuration
Isolated digital output modules provide a suitable interface to
non-critical output devices. These non-critical devices
typically include status alarms or other field devices that are
not used for primary safety shutdown purposes. Although
much of the circuitry on the digital output module is
automatically tested, some logic circuits and the field-side
output switch are simplex and non-tested. This simplex
configuration is illustrated in Figure 3. For safety-critical
outputs requiring fail-safe or fault tolerant output
configurations, Guarded digital output modules should be
used.
Figure 3. Simplex Digital Output Configuration.
Field Wiring
Field wiring terminal blocks on the I/O chassis are used to
connect power sources and loads to the module. The terminal
blocks are located directly above and below the slot where the
module is installed. Each terminal block consists of ten #6
wire clamp screw terminals capable of holding two 12 AWG
wires.
Each output has two terminals for connecting to an isolated
power source and to the output load. Each output is
electrically isolated from the others by a minimum of 2500
volts. Figure 4 shows the proper field wiring connections for
the isolated digital output module.
