Analog Output Modules

(T7470A)

Industrial Control Services

For high integrity applications requiring fail

safe or fault

tolerant analog outputs, guarded analog outputs should be

used.

Field Wiring

For field wiring details, refer to PD

7901

I/O Termination

Assembly (ITA).

Fault Mode Jumper

The fault mode jumper is located behind the ID switch cover

in the lower left

hand corner of each I/O chassis. The position

of the fault mode jumper determines the module's response to

system level faults. The fault mode jumper’s position will

cause all output modules in the I/O chassis to either shutdown

(turn off all outputs) or to hold (hold the las

t state) after a

system level failure occurs. An example of a system level

failure is the failure of two processor modules.

When the analog output module is in the shutdown mode,

analog output signals are at 0 mA (not 4 mA).

Keying

The I/O chassis can be physically keyed to prevent accidental

damage caused by inserting a module into a slot wired for a

different module type. Figure

illustrates how the slot keys

are installed on the I/O chassis slot field wiring connector

The slot key positions for the analog output module are listed

in Table
