Toro GAC Decoders/Modules (24 V AC only)

Toro Lynx GAC decoder modules

Toro DAC-ISP modules connect field stations to a compatible Lynx GAC two-wire gateway. Choose the module by the number of independently controlled stations needed at that location.

Choose the station capacity

• DAC-ISP-1: one station.
• DAC-ISP-2: two stations.
• DAC-ISP-4: four stations.

System and fitting notes

• For Lynx GAC installations using compatible 24 V AC solenoids. Confirm the installed gateway and field design before ordering.
• Toro specifies factory-programmed module addresses and two-way diagnostics for communication, shorts, open circuits, voltage and current.
• The GAC modules include 20 kV surge protection. Grounding and field cable joints must still follow the system design.
• Toro states that the one-station module can fit inside an INFINITY sprinkler with Smart Access. Check the exact sprinkler configuration before selecting this arrangement.

Selection note: GAC AC modules are a different family from Toro GDC DEC-ISP-1 and Lynx LSM-1 modules. Do not choose by station count alone.

See the supporting gallery image for Toro’s DAC-ISP station-count chart and GAC module-selection guidance. The PDF below retains the full gateway, cable-path, electrical and comparison data. Gateway mains-input ratings are not the module’s solenoid-output ratings; use the correct GAC system design and earthing requirements.
