Revision 10 ControlEdge HC900 Process & Safety Controller User and Installation Manual 105
May 2019
8 and 16 channel Analog Output Module Wiring
Hazardous voltages exist at terminal blocks.
AO8 and AO16 modules require at least one channel to be configured prior to a cold start for the module
to work properly. Subsequent channels then may be added with a hot start.
Failure to comply with these instructions could result in death or serious injury.
Examples of high level Analog Output Module wiring are shown in Figure 55 and Figure 56.
Specifications for this module and for other modules are given in the Specifications manual. SIL
applications require an external series relay used to ensure outputs achieve failsafe action. See
ControlEdge HC900 Process & Safety Controller Safety Manual for additional details.
Before installing, be sure to determine power requirements. See page 50 and 89.
Requires Low Voltage Euro style 36-terminal terminal block.
Isolation
The outputs are grouped with 4 outputs per group (outputs 1-4, 5-8, 9-12, 13-16). Groups are isolated
from each other; outputs are non-isolated within each group.
Shield Grounding
Shields must be grounded as described under Shield Grounding at the beginning of this section.
Hazardous voltages exist at terminal blocks.
Using switches at field devices disconnect the field wiring form power sources before servicing.
Failure to comply with these instructions could result in death or serious injury.
