110V/220V AC ± 15% (for power supply units). 2. Schematic & Wiring Guidelines
Install the relay onto a standard DIN rail or into an 11-pin socket base. If using a socket, ensure it is securely fastened to the Control Box Wiring the Coil:
If you don't have a hot air station, you can use a soldering iron (if the fuse is small enough to heat both pads at once) or the "two-iron" method if you have two irons available. As a last resort, use a fine-tipped iron to melt the solder on one pad, gently lift that side, then heat the other pad to remove the component, taking care not to damage the pad.
F4901 11A 24V Schematic & Installation Guide The is a specific industrial-grade relay or solenoid valve controller (often found in heavy-duty HVAC or hydraulic systems) designed to handle high-current loads in a 24V DC environment.
High-current output contacts rated for up to 11A. Ensure wire gauges (typically 14-16 AWG) are sufficient for the 11A load to prevent overheating. Auxiliary Output:
The contact that is "open" (disconnected) when the relay is off. It closes (connects) when the 24V signal is applied to the coil.
EEP‑F4901‑2026‑INST Revision: 1.0 Classification: Technical Application Note
The F4901-11A relies on a multi-wire configuration to manage the internal synchronous motor and the auxiliary end switch. The auxiliary end switch is a critical feature; it acts as dry contacts that close when the valve is fully open, allowing the actuator to signal a boiler, pump, or chiller to turn on only after fluid passage is cleared. Terminal and Wire Identification
Connects directly to the positive terminal of the 24V battery bank. This must be fused.
