Who should use this
AMR, robotic arm, cobot, manufacturing, warehouse and hospital logistics teams organizing safety circuit documentation before integration review.
Resources
Safety, Ruggedization & Field Deployment
Robot Safety Circuit Review Guide
Prepare E-stop, safety relay, safety I/O, safe-stop, scanner, bumper, interlock and validation-boundary inputs for robot safety circuit reviews.
Hardware decision
The guide captures device interfaces and responsibility boundaries without assigning risk-assessment ownership or certifying PL / SIL results.
Prepare before RFQ
Bring E-stop architecture, safety relay or PLC, safety I/O, STO / SS1 or safe-stop interfaces, scanner fields, bumper edges, interlocks, reset logic and customer-supplied PLr / SIL target records.
When to use this guide
Start here if the hardware question affects sourcing, files or RFQ review.
- Safety devices, drives and controllers need a shared interface or wiring record before RFQ.
- E-stop, scanner, bumper, interlock or reset logic affects connector and I/O selection.
- Customer-supplied PLr / SIL targets or risk-assessment records must be attached as review context.
Key engineering decisions
Stop architecture
Map E-stop devices, safety relay or safety PLC, safety I/O and reset logic without assuming validation ownership.
Drive safe-stop interface
Record customer-supplied STO, SS1 or other safe-stop interface requirements and the devices connected to them.
Protective devices
Identify scanner fields, bumper edges, gates, interlocks and any operating-mode dependencies.
Documentation boundary
Separate wiring and interface review from the customer risk assessment, PLr / SIL target selection and final validation plan.
RFQ preparation checklist
Include these inputs before asking for quote or document review.
- Robot platform and operating modes
- E-stop architecture
- Safety relay / safety PLC
- Safety I/O count and voltage
- STO / SS1 / safe-stop interface
- Scanner fields and bumper edges
- Interlock and reset logic
- Customer-supplied PLr / SIL targets, wiring and interface documents
Engineering file considerations
Document access depends on file type and review context.
- Safety wiring diagrams, interface maps and device records may require controlled access review.
- ISO 13849-1, PLr and SIL references are customer-supplied safety-target context, not certification claims.
- Customer risk-assessment records should be identified by intended review purpose and release boundary.
