Jokab JSBR4 Safety Relay

Jokab JSBR4 Safety Relay Specifications:

• Product Type: Safety Relay
• Manufacturer: ABB Jokab Safety
• Model: JSBR4
• Device Application: Monitoring of two-hand devices (type IIIc), emergency stops, interlocked gates/hatches, contact strips, safety mats, foot-operated switches
• Article Numbers / Ordering Data:
  • 2TLJ010002R0000
• Supply Voltage: 24 V DC,
• Power Consumption: 1.3 W (DC)
• Inputs: 2 dual-channel inputs (S13-S14, S23-S24), both must be closed to activate safety outputs
• Input Characteristics:
  • Short-circuit across inputs causes output contacts to open
  • Continuous short-circuit tolerant without relay damage
• Reset Function: Manual supervised reset (close and open reset input X2 to prevent unintentional reset)
  • Reset input monitors contactors/valves for return to initial position
  • Prevents reset if reset button is jammed or short-circuited
• Two-Hand Device Operation: Both buttons must be pressed within 0.5 s to close outputs
• Safety Outputs: 3 N/O (normally open) contacts (13-14, 23-24, 33-34, internally series-connected)
• Auxiliary Output: 1 N/C (normally closed) contact (41-42, for indication only, e.g., gate opened)
• Contact Rating:
  • Max. Switching Capacity: 6 A at 250 V AC, 1500 VA
• Max. Breaking Capacity: Not specified (confirm with supplier; typically matches contact rating)
• Safety Level:
  • Category 4 / PL e (EN 954-1 / EN ISO 13849-1)
  • SIL 3 (EN 61508, assumed based on similar ABB Jokab relays)
• Response Time:
  • Stop signal: Immediate upon short-circuit, input opening, or power failure
  • Reset activation: Requires reset input to close and open
• Connection Type: Screw terminals
• Mounting: DIN rail (35 mm)
• Housing Material: Plastic (black and beige)
• IP Degree of Protection: IP20 (terminals), IP40 (housing, typical for safety relays)
• LED Indication:
  • Power supply: “On” LED
  • Inputs: “In” LED (on when inputs S13-S14, S23-S24 are closed)
  • Outputs: “Out” LED (on when safety outputs are closed)
• Ambient Air Temperature for Operation: -10 to 55 °C
• Ambient Air Temperature for Storage: -40 to 70 °C

• Special Features:
  • 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
• Dimensions:
  • Width: 45 mm
  • Height: 120 mm
  • Depth: 120 mm
• Weight: 0,35 kg
