Two-Hand Operation Monitoring Safety Relay
For machines that pose a significant danger to the human body, dual-hand operation is mandatory, and the time interval for dual-hand operation must be within 500ms. By using our ESR4-NZ-21 for this time-series monitoring, it complies with safety category 3C of EN574.
Safety relays that contribute to the construction of safety circuits for machines!
The miniaturization and slimming of the relay body allows for the reduction in the size of the circuit board. By incorporating an LED, there is no need to design and implement a separate LED circuit, resulting in cost reduction and a decrease in man-hours.
Panasonic safety relay suitable for circuits requiring safety standards.

Safety relay
For monitoring safety circuits, the Müller safety relay ESR series instantly or with a delay interrupts multiple current circuits when the emergency stop mechanism is activated. Depending on the circuit configuration, it can detect short circuits, ground faults, and short circuits in emergency stop circuits. It immediately interrupts after detection or prevents restart until the cause of the fault is removed. Safety relays that comply with Category 4 require an additional restart monitoring function, and our products meet this requirement. This also serves as a mechanism to prevent unauthorized operation. The ESR series complies with either EN954-1 categories 2 to 4, depending on the model. If more contacts are needed, the expansion unit ESR4-NE can increase the number of circuits up to four. For less stringent applications (such as stop category 1 in EN60204-1), the ESR4-NV delayed action safety relay is suitable, allowing for delays of up to 30 seconds.

Any time a relay is required and must be used in a SIF, it must conform and adhere to IEC 61508 and to the relevant industry standard (i.e. 61511). Typical cases : • Controller cannot meet power requirement (V or A) • Multiplication of contacts is required • Controller Safety Function must be inverted SIL certified relays are not used exclusively in Oil & Gas or petrochemical industries; they are also a must in many other industries: • Railways • Cars and lift • Power distribution • Any time a failure of the relay can cause a serious accident [Features] • Reduced foot print: high density, 12,5/22,5 mm per ch. • Full 3rd party certification: Coil-to-Contact SIL2/3 TÜV certified • True reliability: compatible to DO Card LM pulses • Reduced space/eng. Costs: smart line/load monitoring with transparent fault indication (no additional contacts) • Lower ownership/maintenance cost: T-proof times: 10/20 years • Reduced spare inventory: universal mounting: DIN-rail and Termination Boards • Higher reliability in & outdoor: certified -40° to + 70° c • Totally independent dual ch.: dual circuits • Full application coverage: modules available with 5 & 10 Amps contact, NE/ND application • Harsh environment resistance: G3 conformal coating • Reliable switching operations: gold-plated relay contacts *For more details, please download the PDF or feel free to contact us.

In the field of collaborative robots, an environment where humans and robots can coexist safely is essential. If safety is not ensured, there is a risk of personal injury or equipment damage. In particular, abnormal stops or malfunctions of robots can lead to serious accidents. Our safety relay, compliant with functional safety SIL3, provides detection of abnormalities in load, wiring, power supply, and coils under all operating conditions, and transmits independent alarms to the connected DO card on the control system side. This enhances the safety of collaborative robots and creates an environment where work can be performed with peace of mind. 【Use Cases】 - Safety control systems for collaborative robots - Emergency stop circuits for robotic arms - Work areas without safety fences 【Benefits of Implementation】 - Reduced risk of personal injury - Prevention of equipment damage - Improved work efficiency
