Simplex 4090-9008 — dual Form C relay IAM that places two independent contacts on a single IDNet or MAPNET II address.
Reached for when the panel must switch local power for a control function away from the cabinet: elevator capture, HVAC shutdown, damper or fan control. The low-power latching relay design draws both data and module power from the communication line, so no separate 24 V run is needed. Relays sit OFF on power-up and on comms loss.
- Dual Form C (DPDT); Common, N.O. and N.C. per contact
- Power-limited: 2 A @ 30 VDC resistive, 1 A @ 30 VDC inductive
- Non-power-limited: 0.5 A @ 125 VAC resistive; not for incandescent
- Each contact common fused at 2 A fast-acting non-time-delay
- 18 to 14 AWG screw terminals; to 2,500 ft (762 m) from the panel
- 4-1/8" H × 4" W × 1-3/8" D (105 × 102 × 35 mm); 32° to 120°F (0° to 49°C)
IDNet hosts need firmware 3.12.04 or higher. As supplied it fits a 4" (102 mm) square box of at least 2-1/8" (54 mm) depth; a 4-11/16" box needs the 4090-9813 adapter plate.

FAQ
Does it need separate 24 V power?
No. Its low-power latching relay design lets IDNet or MAPNET II communications supply both data and module power.
What happens to the relays on power-up or loss of communication?
The relays are set to OFF on initial power-up and on loss of IDNet or MAPNET II communications.
Which panels support it?
4007ES, 4010ES, 4100ES and 4100U panels on IDNet, and 4100/4100U/4100ES, 4120, 4020 and 2120 CDTs with MAPNET II.
Can it mount in a 4-11/16 in. box?
Yes, with the optional 4090-9813 adapter plate.
