SPS Relay Wiring

Overview

The SPS has one programmable relay, Aux 1, with one set of voltage-free contacts (see

 

below). It also has provision for mounting a 4100-6033 Alarm Relay that has 3 relays,

 

each with one set of normally open (or normally closed) contacts available on a screw

 

terminal block (see fig 6.1).

Aux 1 Relay

 

• The relay must be configured in the Programmer.

 

• The relay circuit is rated to switch 2 A at 30 VAC or 32 VDC, resistive load.

 

• Relay contacts are Form C voltage-free contacts (but with a 40V transorb from

 

common to Earth. Do not switch voltages greater than the rating, or damage may

 

result.

 

• When power through the relay contacts is provided by the SPS 2 A Auxiliary Power,

 

wiring is

 

power-limited.

 

• The relay circuit is not supervised.

Alarm Relay Card

 

The three relays have default functions of Fault (trouble), Isolate (supervisory) and

 

Alarm, and are typically used for Brigade Signalling (refer to chpt 10).

 

• The relays may be configured by the Programmer for alternate functions.

 

• If used as Brigade relays, the jumper must be fitted to the bottom position on P3 on

 

the SPS. If Fault (trouble) is programmed for an alternate function it must be fitted

 

to the top position.

 

• Only one pair of contacts is available for each, and is configured as normally open

 

(NO) or normally closed (NC) by fitting a jumper on the adjacent headers P1

 

(Alarm), P2 (Isolate) and P3 (Fault). Use top position for NC and bottom position

 

for NO.

 

• The relays are each fuse protected (fuse 5 x 15mm, rating 3 A).

 

• Relays are not supervised.
