Pilz PNOZ s3 750103 | Safety Relay 24V DC, 2 NO + 1 NC Aux, DIN Rail, EN ISO 13849-1 PL e, SIL CL 3
Pilz PNOZ s3 (Art. No. 750103) configurable safety relay — 24 V DC supply, 2 NO safety contacts + 1 NC auxiliary, manual/auto reset, EN ISO 13849-1 PL e, SIL CL 3. For E-STOP, guard monitoring, light curtain.
Product Overview
The Pilz PNOZ s3 (Article No. 750103) is a compact configurable safety relay from the PNOZ sigma (PNOZ s) series, designed for monitoring emergency stop (E-STOP) pushbuttons, safety gates, light curtains, and two-hand controls. It operates from a 24 V DC supply (20.4–26.4 V DC) and provides 2 positively driven safety output contacts (NO — make on safe state) plus 1 auxiliary NC contact (signaling). The unit supports manual reset (default) or automatic reset (selectable via DIP switch) and includes semiconductor short-circuit detection (EDM — External Device Monitoring). It achieves EN ISO 13849-1 Category 4 / PL e and IEC 62061 SIL CL 3 / IEC 61508 SIL 3. Width is 22.5 mm — mounts on a standard 35 mm DIN rail.

Series
Pilz PNOZ sigma (PNOZ s) — Compact Safety Relays
Supply Voltage (Us)
24 V DC (Range 20.4 … 26.4 V DC, reverse-polarity protected)
PL e / SIL 3 Certified: Suitable for highest-demand safety functions — E-STOP, guard interlocking, muting, light curtain with OSSD.
Dual-Channel Input with Cross-Fault Detection: Monitors for short between input channels and wiring faults — forces unsafe state if detected.
Manual / Auto Reset + EDM: Flexibly matches machine start-up philosophy; EDM verifies correct functioning of downstream contactors.
Compact 22.5 mm Width: Saves DIN rail space vs. classic PNOZ 1/2 series (45 mm).
LED Diagnostics: Power (green), Safe State / Channel 1&2 (green), Fault (red) — quick troubleshooting.
Typical Applications
Emergency Stop Circuits: Monitoring E-STOP pushbuttons per EN ISO 13850 — ensures controlled machine stop.
Safety Gate / Interlock Monitoring: With positively guided door switches (e.g. PSENmag / PSENmech) — prevents access until hazard cleared.
Light Curtain / Laser Scanner Interface: Evaluating OSSD outputs from type 2/4 optoelectronic ESPE via external test pulse evaluation.
Two-Hand Control (Type III A/C): When used with appropriate input wiring and validation — see Pilz application note for Type III C with PNOZ s3 + PITgate.
PNOZ s3 variants: 750103 = 24V DC, 2 n/o + 1 NC aux (this item). Other common versions: 750104 = 24V DC 3 n/o, 750110 = 115V AC/DC 2 n/o, 750111 = 230V AC/DC 2 n/o. For configurable PNOZ s5/s6/s7 (more inputs/outputs, time delay, logic) see the PNOZ sigma modular range. PNOZ s3 is the direct successor to the classic PNOZ 1 (751001 etc.) in narrower 22.5 mm housing.
