Product Overview
The P7SA-14F-ND-PU DC24 is the front-mounting Push-In Plus socket for Omron's G7SA family of forcibly-guided safety relays in the 6-pole (14-terminal) configuration. It is the dedicated base for a G7SA-2A2B, G7SA-3A1B, G7SA-5A1B, G7SA-4A2B, or G7SA-3A3B relay, and the -ND suffix means the socket ships with a built-in operation-indicator LED and surge-absorbing diode wired across the coil terminals. Use this socket wherever a G7SA relay needs to be plug-in replaceable on the DIN rail rather than soldered to a PCB.
How this socket differs from siblings
The 14-pin count tells you this is for 6-pole G7SA relays, not 4-pole. The narrower 10-pin P7SA-10F-ND-PU DC24 (22.5 mm wide) takes the 4-pole G7SA-3A1B / G7SA-2A2B; the 14-pin P7SA-14F-ND-PU DC24 (27.7 mm wide) takes 6-pole variants and exposes two extra terminals for the additional NO or NC contact. If you need screw terminals instead of Push-In Plus, order the P7SA-14F-ND DC24 (no -PU). If the relay must be soldered to a PCB through the panel, use the back-mounting P7SA-14P with PCB pins.
Wiring and mechanical notes
Push-In Plus terminals accept solid wire, stranded wire, or wire with ferrule — strip length 8.5 mm, use 0.1 to 2.5 mm² (16 to 20 AWG Cu). Insert the wire directly; no screwdriver is required, though a parallel-tip screwdriver can release a conductor if you need to re-wire. The 24 VDC coil of the G7SA relay is fed across terminals A1 (+) and A2 (-) of the socket; the LED indicator wired to these terminals lights when the coil is energised.
Application in a safety circuit
In a typical Cat 4 / PL e guard door circuit, a safety controller (such as a G9SP, NX-SL3300, or G9SE) drives two channels into the coil of a G7SA-2A2B or G7SA-5A1B that sits on this P7SA-14F-ND-PU socket; the NO contacts feed the contactor coils and the NC contacts loop back as EDM feedback. Because the relay is forcibly-guided, a weld on one contact mechanically prevents the opposite contact from closing — the diagnostic loop in the safety controller can detect the fault and stop the machine.
Key Features

- Front-mounting on DIN rail or panel surface, 27.7 × 104 × 65.5 mm
- Holds relay securely under vibration; release lever for fast replacement
- Rated 6 A per pole, 20 A total, 250 V AC across the contact terminals
- cULus, TÜV, CE, and EAC certified for global machinery panels
- SKU: P7SA-14F-ND-PU DC24

Best-Fit Applications
- Plug-in base for G7SA-5A1B / G7SA-4A2B safety relays in robot cell guard-door circuits
- DIN-rail mounting of safety output relays next to NX-SL3300 safety controllers
- Serviceable socket in emergency-stop circuits where relay replacement must be tool-free
- Push-In Plus termination for high-vibration packaging lines where screw terminals would loosen
Buying Checklist
- Use this exact socket when the design calls for a 6-pole G7SA with an LED indicator and 24 VDC coil
- Confirm G7SA pole count before ordering — 4-pole relays fit the 10-pin P7SA-10F-ND-PU, not this 14-pin socket
- For non-Push-In Plus wiring, order the screw-terminal variant P7SA-14F-ND DC24
- Order G7SA relays separately — the socket ships without the relay module
- Pair with XW5S-P2.5-4RD short bars if multiple sockets share a common feed terminal
- Standard DIN-rail socket pitch allows clean panel layout even with mixed 4-pole and 6-pole relays

FAQ for P7SA-14F-ND-PU DC24
Which G7SA relays fit the P7SA-14F-ND-PU DC24?
All 6-pole (14-terminal) variants of the G7SA family: G7SA-2A2B (DPST-NO + DPST-NC), G7SA-3A1B (3PST-NO + SPST-NC), G7SA-5A1B (5PST-NO + SPST-NC), G7SA-4A2B (4PST-NO + DPST-NC), and G7SA-3A3B (3PST-NO + 3PST-NC). All accept 12, 18, 21, 24, 48, and 110 VDC coils. The 4-pole G7SA relays (G7SA-2A2B, G7SA-3A1B) do fit both 10-pin and 14-pin sockets, but the 6-pole variants only fit the 14-pin socket.
What is the difference between P7SA-14F-ND-PU and P7SA-14F-ND?
The -PU suffix indicates Push-In Plus screwless terminals; the plain -ND ends with screw terminals. Both have the 24 VDC LED indicator and built-in diode. Push-In Plus reduces wiring time by about 60% compared to screw terminals and resists vibration-induced loosening, but you need ferrules or solid wire for the best connection.
How do I read the LED indicator on this socket?
The LED is wired in parallel with the coil (terminals A1 / A2 on the relay, exposed as the top two terminals of the socket). When the safety controller energises the coil at 24 VDC, the LED illuminates; when the coil drops out — either by E-stop, guard-door open, or controller shutdown — the LED extinguishes. If the LED stays on when the controller commands drop-out, the relay contacts are welded and the relay must be replaced.
Is this socket certified for use in functional-safety circuits?
The P7SA socket itself carries cULus, CSA, TÜV, CE, and EAC marks for industrial machinery. Functional-safety certification (Cat 4 / PL e per ISO 13849-1, SIL3 per IEC 61508) belongs to the G7SA relay sitting in the socket and the surrounding safety circuit; the socket is the wiring interface, not the safety component. Designs targeting PL e must use a G7SA with forcibly-guided contacts, a certified safety controller, and dual-channel wiring.
