The Toro CDEC-ISP-2 is a compact, field-mount two-wire decoder module designed for TDC and GDC irrigation controllers. It delivers reliable station control while minimizing trenching and wiring costs for commercial and large landscape installations. 2-station two-wire decoder compatible with Toro TDC/GDC controllers and gateways. Operates up to four DC latching solenoids (two coils per station) for multi-valve configurations. Integrated ISP surge protection rated up to 20 kV to reduce lightning-related failures and field damage. Accepts 120/220/240 VAC input and supplies approximately 38–40 VAC output for solenoid operation. Low holding current DC latching design for energy-efficient valve actuation and extended cable runs. Durable, vandal-resistant enclosure with electronic address programming and two-way diagnostics for easier troubleshooting. Use the CDEC-ISP-2 to upgrade conventional valve wiring to a two-wire TDC system, simplify installation, and reduce ongoing maintenance. Always consult Toro technical documentation or your controller manual for wiring diagrams, address programming, recommended cable specifications, and safety procedures prior to installation.
