2R9 Series
The 2R9 Series of relays are designed and manufactured to be the longest-lasting, most reliable relays available. By incorporating a unique single moving part (the contacts) design, both endurance and reliability are significantly enhanced. Compare our 200,000 ON/OFF cycle FULL LOAD and 1,000,000 no load ratings with any other relay in the industry. We're confident you will agree that for reliability and endurance, ILC's 2R9 Relay Series simply can't be beat. ILC 2R9 relays are magnetically latched, requiring only a momentary rectified AC or DC pulse to open or close the contacts.- Magnetically latching contacts
- 1 amp 30 volts AC/DC isolated contacts for status feedback or pilot lights
- Single moving part design
- Operates in any position
- Unmatched endurance (Ind. Lab Test)
- 200,000 (ON/OFF) cycles, at FULL LOAD
- 1,000,000 (ON/OFF) cycles, at no load
- 20 amp 120, 277 or 347 VAC operation
- UL listed, FCC approval for commercial and residential use
Features
General Information
- UL Listed
- Mounts in standard ½" K.O. .825" - .875" diameter, 14 or 16 gauge material
- Operates in any position
Line Voltage Characteristics
- Contacts: SPST Maintained (permanent magnet latching)
- Terminals:2 terminals, 2 back wiring holes per terminal for feed through wiring
- Screw-actuated clamps for use with #14-10AWG solid or stranded copper wire only
Low Voltage Characteristics
- Split coil: ½ for "ON", ½ for "OFF"
- Compatible with standard interface drivers
- Operating voltage:
- 18 - 30 VAC rectified
- 12 - 24 VDC filtered
- Duty rating: Momentary
- Minimum activating pulse time: 17 milliseconds
- Coil Impedance: 68 - 73 ohms at 60Hz, 50 - 60 ohms DC resistance
- Switching power required for each 2R relay is:
- 2.2 VA per relay at 24 VAC rectified
- 175 mA per relay at 12 VDC
- 350 mA per relay at 24 VDC
- Status contacts: 1 amp AC/DC
Application Considerations
- Relays Connected in Parallel - Two or more relays connected in parallel, by grouping red leads and black leads, will operate together. The maximum number of relays connected in parallel is determined by the capacity of the power supply and the switch contact rating.
