Space Age SSU-MR-201/C/R — single-position MR-200 Series multi-voltage control relay, DPDT contacts, in a backbox under a red cover.
One relay accepts any of four control voltages: wire the coil to the matching input terminal and the same part serves a 24 V panel output, a 120 VAC circuit or a 230 VAC circuit. A red LED lights when the coil is energized.
- Coil accepts 24 (18 to 35) VDC, 24 VAC, 120 VAC or 230 VAC; DC input polarized
- One module position, dry Form C DPDT contacts
- Contacts rated 7 A at 28 VDC, 10 A at 120 VAC, 7 A at 230 VAC
- 40 mA per position; continuous duty at 24 VAC, 24 VDC or 120 VAC, not at 230 VAC
- Enclosure 5.125" H × 3.125" W × 2.50" D, 18ga steel backbox, 1/2" knockouts
- Terminals take #14 to #22 AWG; rated 32 to 120 °F
- UL listed as a Control Unit Accessory and for UUKL smoke control
The suffixes carry the whole difference. SSU-MR-201/C is the same relay under a grey cover, SSU-MR-201/T is track-mounted with no enclosure, SSU-MR-204/C/R has four positions, and SSU-MR-101/C/R is the SPDT relay of the MR-100 line.
