Product Overview
The Omron P7SA-10F-ND is a 4-pole relay socket for the G7SA family of safety relays. It is the BASE / HOLDER -- the relay itself, the G7SA-3A1B or G7SA-2A2B, is a separate line item that snaps into the socket. The socket carries the wiring to the relay's coil (A1 / A2) and to its four contact poles (the 11-12 / 13-14 / 21-22 / ... pattern on the terminal block), and adds the panel-side spacing for a 35 mm DIN rail or surface panel mount.
What the -ND suffix means
P7SA sockets carry a -F (screw terminals) or -P (PCB back-mount) terminal style and a trailing letter that signals whether the socket has the action indicator light. The P7SA-10F is the bare socket with no LED; the P7SA-10F-ND (this SKU) adds an LED that lights when the matching G7SA coil is energised -- so service techs can see at a glance whether the safety relay is armed. The -PU suffix means Push-In Plus terminals; this screw-terminal SKU is the original / lower-cost form.
What this socket does NOT do
The socket alone provides no safety function -- it is a passive wiring holder. The safety category (Cat 1, Cat 3, Cat 4 / PL e, SIL 3) is set by the wiring scheme plus the upstream safety controller that drives the coil. The G7SA relay provides the forced-guided contacts that make Cat 4 / PL e with redundancy possible -- match the relay to the channel count (G7SA-3A1B = 3 N/O + 1 N/C, the common pick; G7SA-2A2B = 2 N/O + 2 N/C), both snap into this 10-pin 4-pole socket.
Before ordering
Order the matching G7SA relay at the same time -- this socket is incomplete by itself. Match the relay coil voltage to the cabinet rail: the -ND24 on this SKU is the 24 VDC coil variant with LED; the bare P7SA-10F (no ND suffix) accepts any G7SA coil voltage across the DC range. Seat the G7SA relay into the socket and push the yellow release lever down until it clicks; lift the lever up to remove the relay for bench-side swap-out.
Key Features
- P7SA-series 4-pole relay SOCKET (base / holder, not the relay)
- Holds the G7SA family of safety relays (G7SA-3A1B, G7SA-2A2B, G7SA-5A1B sold separately)
- 10 pins matching the 4-pole G7SA contact pattern (4 NO + 1 NC pairs)
- M3 screw-terminal wiring on the coil and contact sides
- WITH action indicator LED that lights when the G7SA coil is energised
- Yellow / orange release lever on the front for relay swap-out
- 22.5 mm wide on a 35 mm top-hat DIN rail (IEC 60715) or surface mount via M4 holes
- 6 A max per pole / 20 A total per socket / 288 V AC max per cULus rating
- Compatible with the G7SA relay coils from 12 VDC through 110 VDC (the socket is universal; the LED variant is the 24 VDC coil)
- cULus / TUV / VDE / CE / EAC approved
- 60.5 mm height, screw-terminal depth ~83 mm
- SKU: P7SA-10F-ND
- Series: P7SA-10F-ND
- Voltage: 24 VDC
Best-Fit Applications
- DIN-rail socket for a 24 VDC G7SA safety relay inside an emergency-stop and guard-door interlock panel
- Spare-base replacement in safety cabinets where the G7SA relay is treated as a serviceable part
- Socket for the 4-pole G7SA family in machine-safety panels with mixed AC and DC contactor logic
- Indicator-equipped socket for cabinets where the technician needs to see at a glance whether the safety relay is armed
- Spare socket in service stock so a failed G7SA relay can be replaced on the panel without disturbing the wiring
Buying Checklist
- Pick P7SA-10F-ND when you want the 4-pole G7SA socket WITH the action indicator LED on a 24 VDC coil.
- Pick P7SA-10F instead when the indicator LED is unnecessary and the coil voltage varies.
- Pick P7SA-10F-ND-PU for Push-In Plus terminals (no M3 screwdriver) when wiring speed matters.
- Pick P7SA-14F-ND for a 6-pole G7SA socket (the G7SA-5A1B or G7SA-4A2B relay).
- Pick P7SA-10P for the back-mount PCB socket when the socket is hard-wired onto the cabinet's PCB.
- Order the matching G7SA relay in the same order -- the socket alone does nothing.

FAQ for P7SA-10F-ND
Does the P7SA-10F-ND include the safety relay?
No. The P7SA-10F-ND is the SOCKET / BASE only. The relay itself -- the G7SA-3A1B (3 NO + 1 NC) or the G7SA-2A2B (2 NO + 2 NC) -- is a separate line item that snaps into the socket. The socket holds the relay, lands the wiring, and adds the action indicator LED; the relay carries the forced-guided contacts that make Cat 4 / PL e safety interlock possible.
What is the difference between P7SA-10F and P7SA-10F-ND?
The ND suffix adds an action-indicator LED on the socket that lights when the G7SA coil is energised. The P7SA-10F (no ND) is the bare socket with no LED; this P7SA-10F-ND is the same socket with the LED added. Both are 4-pole, both use M3 screw terminals. The -PU suffix on P7SA-10F-ND-PU switches the terminals to Push-In Plus instead of screw.
Can this socket achieve Cat 4 / PL e by itself?
No. The socket is a passive wiring holder and cannot claim any safety category. Cat 4 / PL e (or SIL 3 per IEC 61508) requires the G7SA relay's forced-guided contacts PLUS dual-channel wiring from the safety input device (E-stop or guard switch) PLUS an upstream safety controller or safety relay (G9SA-301, G9SP, or the matching safety controller in the panel). One socket with one channel of wiring caps at a lower category (Cat 1 or Cat 2 typically).
Which G7SA relay fits the P7SA-10F-ND?
Any 4-pole G7SA relay: G7SA-3A1B (3 NO + 1 NC, the most common pick), G7SA-2A2B (2 NO + 2 NC). Order the relay by coil voltage to match the cabinet's 24 VDC or other DC rail. The 6-pole G7SA-5A1B / G7SA-4A2B / G7SA-3A3B will NOT fit this 4-pole socket -- those need the wider P7SA-14F-ND or P7SA-14F-ND-PU socket.
