The Multiquip 20705 Relay is a genuine OEM Relay designed for the C30HD concrete pump. Sourced directly from Multiquip, this relay meets the exact electrical specifications required by the C30HD, ensuring proper fit and function within the machine's control circuit. DHS Equipment supplies this part as an authorized Multiquip OEM replacement, giving you confidence that you're installing the correct component the first time.
Key Features
- OEM Electrical Specification Match — Correct coil voltage and contact rating engineered to the exact switching demands of the C30HD control system.
- Drop-In Replacement — Mounts directly to the existing relay socket on the C30HD with no additional wiring or terminal modification required.
- C30HD Concrete Pump Compatibility — Verified fitment for the Multiquip C30HD, eliminating guesswork when ordering for this machine.
- Consistent Pump Control Response — A properly functioning relay ensures clean, decisive switching of pump functions; a worn or failed relay can cause erratic operation or complete loss of circuit control.
- Electrical Safety Integrity — Using the correctly rated OEM relay prevents overloading the control circuit, protecting downstream electrical components from damage caused by an undersized or mismatched substitute.
A relay is an electrically operated switch that allows a low-power control signal to open or close a higher-current circuit within the machine. On a concrete pump like the C30HD, relays are used to manage motor starts, pump direction, and other key operating functions without routing full load current through the control panel switches. When a relay fails, it can cause functions to stop responding, cycle erratically, or refuse to engage — bringing the pump to a halt until the faulty component is replaced.
