Complete plug-and-play wireless control system – includes the handheld transmitter and the receiver, coded together at the factory and ready to wire to your equipment. Operates 4 functions.
The 4 Function Roll-Off Wireless Control System (PS004B) gives you 4-function wireless control with a 150 ft (45 m) range. DC FET output switching, 3 A per output, 12/24V DC. This system ships with roll-off trailer firmware for a winch and hydraulic pump option. Its master output is active only on the hydraulic pump functions (F3 and F4), not on every function.
How do I know this system fits my equipment?
Match the function count to the number of outputs you need to operate – 4 here – and confirm your power supply: this system runs on 12/24V DC. Each FET output is rated to 3 A, with the system rated to 5 A total — enough to switch most solenoids and valves — and the solid-state design trips its overload at 5 A to protect the board. The transmitter and receiver ship coded to each other, so the system works out of the box.
