The JSBR4 has two inputs, which both have to be closed to keep the safety output contacts closed. A short‑circuit across the inputs will cause the output contacts to open. The inputs can however be subjected to a continuous short‑circuit without damaging the safety relay. The JSBR4 has a twin supervised safety function. The JSBR4 operates at the highest safety level for safety relays.
