You only need wiring to construct a safety circuit. No programming or setting is necessary.
Connect a safety relay module for expansion, so that you can use 4 safety inputs and safety outputs at the maximum.
These modules are optimal for a small-scale safety control. The modules are authorized by certifications at the highest safety level (EN954-1/ISO13849-1 category 4/performance level E).
If a trouble should occur in the module, the fail-safe function stops operation safely.
Since the spring clamp terminal block is adopted, you do not need to fasten any screws. Your wiring workload will be considerably reduced.
