8.6 Series 3 Rack Optional Relay Specifications

8.6.1 Relay Output Contacts

Relay output contacts: Via PLC, normally open (form A). Available in 88 and 176 contacts, both
are user configurable. Factory default setting include A1 and A2 alarms per point as well as 9
general analyzer A1, 9 general analyzer A2, 9 analyzer fault/maintenance and 5 open.

The alarm relay has a minimum load requirement of greater than 5 volts and 10 mA. For
reliable relay operation, ensure the alarm circuit meets these requirements.

(1) Calculated based on the Rockwell Automation component derating guideline: 90% of
rated contact current, that is, 0.3 A at 125V DC. Connecting surge suppressors across your
external load will extend the life of CompactLogix 5380 relay contacts. For recommended
surge suppressor when switching AC inductive loads, consult the CompactLogix 5380
Controllers Installation Instructions (5069-IN013H-EN- P).
(2) For DC voltage applications, the make/break ampere rating for relay contacts is
determined by dividing 28VA by the applied DC voltage. For example, 28VA/48V DC = 0.58
