Relay Base (14-Pin, PYF08A) – Complete Guide
The PYF08A is a 14-pin relay socket/base designed to securely mount and connect 14-pin relays (e.g., Omron MY4N, Schneider RXM). Below are its specifications, wiring, compatible relays, and alternatives.
???? 1. Key Specifications
| Parameter | Details |
|---|---|
| Pin Count | 14 pins (matching standard 14-pin relays) |
| Mounting | DIN rail (35mm) or panel mount |
| Terminal Type | Screw clamp (for secure wiring) |
| Material | Thermoplastic (PA66), flame-retardant (UL94 V0) |
| Rated Current | 10A per contact (depends on relay used) |
| Rated Voltage | 300V AC/DC (insulation voltage) |
| Compatibility | Fits MY4N (Omron), RXM (Schneider), LY4 (Fuji), etc. |
???? 2. Wiring & Pinout (14-Pin Relay Base)
Standard 14-Pin Relay Base (PYF08A) Pin Configuration:
| Pin | Function | Connection |
|---|---|---|
| 1 | Coil (A1) | Relay coil (+) |
| 2 | Coil (A2) | Relay coil (−) |
| 3 | Common (11) | NO/NC contact |
| 4 | Normally Closed (12) | NC contact |
| 5 | Normally Open (14) | NO contact |
| 6 | Common (21) | NO/NC contact |
| 7 | Normally Closed (22) | NC contact |
| 8 | Normally Open (24) | NO contact |
| 9 | Common (31) | NO/NC contact |
| 10 | Normally Closed (32) | NC contact |
| 11 | Normally Open (34) | NO contact |
| 12 | Common (41) | NO/NC contact |
| 13 | Normally Closed (42) | NC contact |
| 14 | Normally Open (44) | NO contact |
???? Note:
Pins 1 & 2 control the relay coil (A1/A2).
Pins 3–14 are switch contacts (4x NO/NC/Common).
???? 3. Compatible Relays
The PYF08A base works with standard 14-pin relays, including:
Omron MY4N (10A, 250V AC)
Schneider RXM4LB2BD (8A, 250V AC)
Fuji LY4 (10A, 240V AC)
Siemens 3TX7004-1A (6A, 400V AC)
⚠️ Check relay datasheet for exact compatibility.
???? 4. Installation Guide
Mount the base on a DIN rail (35mm) or panel.
Insert the relay into the socket (align pins correctly).
Wire connections:
Coil (A1/A2): Connect control voltage (e.g., 24V DC).
NO/NC contacts: Connect load wiring (e.g., motor, lamp).
Secure screws (torque ~0.4–0.6 Nm).
???? 5. Applications
✔ Industrial control panels (PLC systems)
✔ Motor control circuits
✔ HVAC & lighting automation
✔ Power distribution systems
???? 6. Alternatives & Buying Tips
Equivalent 14-Pin Relay Bases:
Omron PYF14A (higher durability)
Schneider ZBE-1014 (screwless clamp)
Finder 95.14 (push-in terminals)
Buying Checklist:
✅ Verify relay compatibility (e.g., MY4N, RXM).
✅ Check screw terminal size (supports 1.5–4mm² wire).
✅ DIN rail or direct mount?
???? 7. FAQ
Q: Can I use an 8-pin relay in a 14-pin base?
→ No, the pin layout is different. Use an 8-pin base (PYF08A-E) instead.
Q: What’s the max current for PYF08A?
→ 10A per contact (depends on the relay used).
Q: Is the base reusable?
→ Yes, relays can be swapped without rewiring.
???? Need a Wiring Diagram or Relay Recommendation?
Specify:
Relay model (e.g., MY4N, RXM).
Control voltage (e.g., 24V DC, 120V AC).
Load details (e.g., 5A motor, 230V AC).
