This 24V solid state relay is the switch that protects the pressure switch on your Remco Zeus soft wash pump. It carries the motor's load current electronically, so the mechanical switch contacts don't arc and burn out. Rated for 24VDC and 40 amps. Key Features Protects the pressure switch: It carries the motor's switching current, so the pressure switch handles only a low-current signal and stops arcing and welding its contacts. No moving contacts: A solid state switch has nothing to pit or wear, so it switches faster and outlasts the mechanical relay it protects. Made for the 24V Zeus: It's the 24 VDC relay for the Remco Zeus pump, not the 12V pumps, which use a different pressure-switch assembly. Wired and ready to mount: The leads are labeled POWER IN and POWER OUT, and mounting screws are included. Specifications Type DC solid state relay (no moving contacts) Rated for 24 VDC, 40 A Wiring Pre-attached leads, labeled POWER IN / POWER OUT Mounting Surface mount, screws included For Remco Zeus 24V soft wash pump What's Included One solid state relay Mounting screws Built for the 24 VDC Remco Zeus soft wash pump. It's a DC switch for a DC motor, not for AC power, and the voltage has to match the system, so it doesn't go on a 12V rig. The 12V Remco pumps use a different pressure-switch and relay assembly. Soft wash rigs sit in SH fumes that corrode electronics, so mount the relay in a dry, ventilated spot away from spray and grease the connections. How It Works A solid state relay is an electronic switch with no moving contacts. On the Zeus it sits in the motor power path, POWER IN from the fused 24V supply and POWER OUT to the pump motor. The pressure switch then handles only a small control signal instead of the motor's full running and inrush current. That's what keeps the mechanical contacts from arcing and welding, which is the usual reason a pressure switch burns out and the pump starts short-cycling or won't shut off.

It lets the low-current control signal switch the motor's high current electronically, so the mechanical pressure switch contacts don't arc and burn out. That's what extends pressure-switch and pump life. Is this relay for a 12V or 24V pump? 24 VDC. It's the relay for the 24V Remco Zeus pump. The 12V Remco pumps use a different pressure-switch and relay assembly, so match the relay to your system voltage. How do I wire it? The leads are labeled POWER IN and POWER OUT, and it mounts with the included screws in the motor power path. Mount it away from direct spray and seal the connections, since SH fumes corrode electrical contacts.
