Single-channel and dual channel versions are available for the construction of safety applications. The internal logic of the safety relays monitors the safety circuits (emergency stop, guard door, and so on) and activates the enable paths in a fault-free condition. Upon actuation of the safety device or in the even of a fault, the enable paths are switched off. Any faults that occur in the control circuit, such as ground fault, cross connection fault or wire breakage are also detected. ## **Application Description** Eaton’s ESR5 safety relays provide optimal safety and a high degree of reliability on plant machinery. Applications that meet the highest safety requirements in accordance with EN 954-1, EN ISO 13849-1 up to PL e and accordance with IEC 62061 up to SILCL 3 can be realized with the ESR5 safety relay. Compatible with a wide variety of safety devices: - Emergency stops - Rope pulls - Two-hand control stations - Light curtain (OSSD) - Gate enable device - Safety switches ## **Contents** **==> picture [243 x 55] intentionally omitted <==** **----- Start of picture text -----**<br> ||| |---|---| |Description|Page| |Safety Relays| |Product Selection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .|3| |Technical Data and Specifications . . . . . . . . . . . . . . . . .|4| |Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .|7| **----- End of picture text -----**<br> ## **Standards and** ## **Features** - UL 508; CSA-C22.2 No 14-95; CE Marked - Use for the highest safety requirements in accordance with EN 954-1 EN ISO 13849-1, IEC 62061 and EC 61508 - UL/cUL file number: E29184 - Degree of protection: IP20 - Suitable for the world market with UL, cUL certifications and TÜV Rhineland functional safety certifications - TÜV Rhineland certified - UL/cULus listed - Applicable for EN 60204 stop categories 0 or 1 - Plug-in screw terminals for fast and fault-free replacement - Multi-voltage versions (24–230 Vac/Vdc) for a flexible range of application - Delayed and non-delayed contact expansions accommodate a wide variety of applications **Control Relays and Timers** CA04902001E—March 2011 www.eaton.com **2** > Control Relays and Timers 40.10 Safety Relays ## **Product Selection** ## **Safety Relays** ## **Technical Overview** |**Technical Overview**|**Technical Overview**|**Technical Overview**||||||||||**40**| |---|---|---|---|---|---|---|---|---|---|---|---|---| ||||**Safety**||**Signal**|||**Removable**||||**40**| |**Single**<br>**Channel**|**Dual**<br>**Channel**|**Safety**<br>**Output (NO)**|**Output (NO)**<br>**(Delayed)**|**Output**<br>**Delay**|**Output**<br>**(NC)**|**Feedback**<br>**Output**|**Control**<br>**Voltage**|**Terminal**<br>**Blocks**|**Type of**<br>**Unit**|**Catalog Number**||**40**| |■<br>■|—<br>■|4<br>2|—<br>—|—<br>—|1<br>—<br>1<br>—<br>~~—,—_—~~||24 Vac/Vdc<br>24 Vac/Vdc|■<br>■|Main<br>Main|**ESR5-NO-41-24VAC-DC**<br>**ESR5-NO-21-24VAC-DC**||**40**| |■<br>■|■<br>■|3<br>3|—<br>—|—<br>—|1<br>1|—<br>—|24 Vac/Vdc<br>230 Vac|■<br>■|Main<br>Main|**ESR5-NO-31-24VAC-DC**<br>**ESR5-NO-31-230VAC**||**40**| |■|■|3|—|—|1|—|24–230 Vac/Vdc|■|Main|**ESR5-NO-31-AC-DC**||**40**| |■|■|2|2|0.1–30s|—|—|24 Vdc|■|Main|**ESR5-NV3-30**||| |—|■|2|—|—|1|—|24 Vac/Vdc|■|Main|**ESR5-NZ-21-24VAC-DC**||**40**| |■<br>■|—<br>—|5<br>—|—<br>4|—<br>0.3–3s|1<br>1|1<br>1|24 Vac/Vdc<br>24 Vdc|■<br>■|Expansion<br>Expansion|**ESR5-NE-51-24VAC-DC**<br>**ESR5-VE3-42**||**40**| ## **Application Overview** |**Emergency**|**Safety**|**Light Curtain/**|**Light Curtain/**|**Two-Hand Control**|**Contact**||**Cross Circuit**|**Monitored**||| |---|---|---|---|---|---|---|---|---|---|---| |**Stop**<br>■|**Switches**<br>■|**OSSD**<br>—|**OSSD**<br>®|**(EN 574 Type III C)**<br>—|**Expansion**<br>—|**Off-Delayed**<br>—|**Recognition**<br>—|**Manual Reset**<br>—|**Manual Reset**<br>@|**Catalog Number**<br>**ESR5-NO-41-24VAC-DC**| |■|■|—||—|—|—|■|—||**ESR5-NO-21-24VAC-DC**| |■|■|—||—|—|—|■|—||**ESR5-NO-31-24VAC-DC**| |■|■|—||—|—|—|■|■||**ESR5-NO-31-230VAC**| |■|■|—||—|—|—|■|■||**ESR5-NO-31-AC-DC**| |■|■|■||—|—|■|■|■||**ESR5-NV3-30**| |—<br>—|■<br>—|—<br>—||■<br>—|—<br>■|—<br>—|■<br>—|—<br>—||**ESR5-NZ-21-24VAC-DC**<br>**ESR5-NE-51-24VAC-DC**| |—|—|—||—|■|■|—|—||**ESR5-VE3-42**| |**Application Overview, continued**|**Application Overview, continued**|**Application Overview, continued**||||| |---|---|---|---|---|---|---| |**Single**|**Dual**|**Stop Category**|**Control Category**|**Achievable PL per**|**Achievable SIL per**|| |**Channel**|**Channel**|**EN 60204**|**to EN 954-1**|**ISO 13849-1**|**EN IEC 62061**|**Catalog Number**| |■|—|0|2|PL d|SIL 3|**ESR5-NO-41-24VAC-DC**| |■|■|0|4|PL e|SIL 3|**ESR5-NO-21-24VAC-DC**| |■|■|0|4|PL e|SIL 3|**ESR5-NO-31-24VAC-DC**| |■|■|0|4|PL e|SIL 3|**ESR5-NO-31-230VAC**| |■<br>■|■<br>■|0<br>0/1|4<br>4|PL e<br>PL e|SIL 3<br>SIL 3|**ESR5-NO-31-AC-DC**<br>**ESR5-NV3-30**| |—|■|0|4|PL e|SIL 3|**ESR5-NZ-21-24VAC-DC**| |■|—|0|4|PL e|SIL 3|**ESR5-NE-51-24VAC-DC**| |■|—|1|3|PL d|SIL 2|**ESR5-VE3-42**| ## _**Notes**_ Laser scanners or light curtains with OSSD outputs.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
