Jokab JSBR4 Safety Relay

2TLJ010002R0000

Short-circuit across inputs causes output contacts to open

Continuous short-circuit tolerant without relay damage

Reset input monitors contactors/valves for return to initial position

Prevents reset if reset button is jammed or short-circuited

Category 4 / PL e (EN 954-1 / EN ISO 13849-1)

SIL 3 (EN 61508, assumed based on similar ABB Jokab relays)

Ambient Air Temperature for Operation: -10 to 55 °C

Ambient Air Temperature for Storage: -40 to 70 °C

Dual supervised safety function (no dangerous function on component failure, short-circuit, or external disturbance)

Robust design tolerates continuous short-circuits without damage

Suitable for safety mats/strips (stop on short-circuit between channels A and B)

Test input for monitoring contactors/valves
