The 2TLA010025R0000: With a lifecycle stage of current, this safety relay is not subject to a last-time-buy or phase-out notice. It is available through normal distribution and can be specified into new designs or used as a direct replacement for existing JSBRT11 installations without concern for imminent obsolescence.
As a safety relay, it is wired into the safety circuit between the emergency stop or light curtain output and the contactors or motor starters that must be de-energized in a fault condition. The 24 VDC coil voltage matches common PLC and safety controller supply rails.
