Simplex 2088-9021 — encapsulated SPDT multi-voltage control relay (PAM-1) with coil status LED.
Reach for this when an auxiliary function has to be switched from an existing panel output without burning an addressable point. The potted body accepts 18–35 V AC or DC, 120 VAC or 240 VAC on separate leads, so one part covers both low-voltage and line-voltage circuits; DC inputs are diode polarized. The red LED shows when the coil is energized.
- Contacts: SPDT (Form C), 10 A @ 120 VAC resistive
- Coil: 18–35 VAC/VDC, 120 VAC, or 240 VAC
- Coil current: 15 mA @ 24 VAC/VDC and @ 120 or 230 VAC
- 18 AWG color-coded flying leads
- 1-1/2" H × 1" W × 7/8" D
- 32° to 120°F; UL 864 Control Unit Accessory
Not interchangeable with the 4098-9843 (PAM-SD): the PAM-SD has a polarized 18–32 VDC coil with in/out wiring, no LED, and contacts rated 7 A @ 28 VDC and 120 VAC plus 250 µA @ 5 VDC. If the drawing calls for supervised in/out coil wiring or logic-level switching, order 4098-9843.
