AC Guarded Digital Output Module

(T3464)

Industrial Control Services

To program fault tolerant outputs two output coils driven by

the same control logic are used as shown in Figure

Figure

. Programming Fault Tolerant Outputs.

In this illustration A, B, C, D represent various logic elements

used to drive the outputs; XV103A represents the output on

e Guarded output module; and XV103B represents the

output on the other Guarded output module.

Maintenance

No periodic maintenance or calibration is required for this

module.

Fuses can be removed and replaced without removing the

module from the I/O chassis. Turning the fuse holder one

quarter turn from its locked position releases the fuse holder,

extending the fuse and allowing it to be removed.

To prevent damage to the module, replacement fuses must be

of the same rating and type (see Specifications, bel

ow).

Diagnostic Messages

When the module is first inserted into an I/O chassis or when

system power is applied, the display will go through the

initialization sequence shown in Table
