A.1 Relay Output Contacts
Relay output contacts: via PLC, normally open
(form A). Available in 32 and 64 contacts, both are user
configurable.
A.2 Relay Contact Ratings
• 0.1 to 2.0 Amps
• 5-24 VDC or
• 5-120 VAC
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) Connecting surge suppressors across your external load will
extend the life of SLC 500 relay contacts. For recommended surge
suppressor when switching AC inductive loads, consult the SLC
500 Modular Hardware Style Installation and Operation User
Manual (Publication 1747-6.2) or the SLC 500 Fixed Hardware
Style Installation and Operation User Manual (Publication 1747-
6.2.1). Recommended surge suppression for switching 24 VDC
inductive loads is a 1N4004 diode reverse wired across the load.
(2) The continuous current per module must be limited so the
module power does not exceed 1440 VA.
(3) For DC voltage applications, the make/break ampere rating
for relay contacts can be determined by dividing the 28 VA by the
applied DC voltage. For example, 28 VA / 48 VDC = 0.58A. For DC
voltage applications less than 14V, the make/break ratings for relay
contacts cannot exceed 2A. RTB = Removable Terminal Block.
