Space Age SSU-PAM-1 — encapsulated Gator Relays multi-voltage control relay with one SPDT contact set and six flying leads.
It puts a set of dry contacts wherever a fire alarm, smoke control or building automation circuit needs one, with no enclosure: the body is potted and ships with a screw, tape and wire nuts. Three of the leads select the coil input, so one part serves 24 Vac, 24 Vdc and 120 Vac. A red LED shows the coil energised.
- One SPDT continuous-duty coil, 10 million cycles mechanical, 8 ms operate time
- Coil input 24 Vac, 24 Vdc or 120 Vac at 50 to 60 Hz; pull in 16 Vac or 18 Vdc
- Coil current 20 mA at 24 Vdc, 50 mA at 24 Vac and 30 mA at 120 Vac
- Contacts 10 A general use at 120 Vac; 10 A resistive at 30 Vdc normally open, 7 A normally closed
- Six leads, 12 in., 600 V rated; body 1.5 × 1.2 × 1.2 in.
- UL 864 and UUKL smoke control, C-UL, CE, RoHS and CSFM
SSU-PAM-2 and SSU-PAM-4 are the 9 to 40 Vdc versions, SSU-PAM-SD the 20 to 32 Vdc one and SSU-PAM-EOLR the SPST one. The Air Products and Controls PAM-1 shares the name and is a different part under a different listing file.

FAQ
How is the coil voltage selected?
By the lead used: white/black for 120 VAC or white/red (+) for 24 VAC/VDC, with white/yellow (−) as the coil common.
Which leads are the contacts?
Yellow is common, orange is normally open and blue is normally closed (one SPDT set).
What are the pull-in and drop-out voltages?
Pull in is 16 VAC or 18 VDC and drop out is 10 VAC or 10 VDC.
What is the operating temperature?
−30°F to 104°F at 5 to 95% non-condensing humidity.
