      SCHMERSAL SRB-NA-R-C.35-CH2A-24V belongs to the SRB-NA-R-C.35 24 V safety-relay family for emergency-stop and guard-door monitoring. The supplied family catalog defines the common 24 V electrical and installation data but does not decode the complete CH2A suffix.
      • Provides emergency-stop or guard-door monitoring within the SRB-NA-R-C.35 family
      • Provides four enabling outputs and one monitoring output
      • Includes one delayed enabling output adjustable from 0 to 30 seconds
      • Supports feedback-loop monitoring and selectable reset behavior

      Monitors a documented single- or dual-channel emergency-stop circuit. Monitors an approved safety-door circuit and controls enabling contacts.

      Important Notice: The supplied ELAN/Schmersal catalog supports the SRB-NA-R-C.35 24 V family values. It does not define the complete CH2A suffix, so option-specific data must be verified from the installed nameplate and controlled wiring documentation.

      These documents are different: the first consolidates verified product and system data; the second provides installation, connection, commissioning and acceptance guidance.

      Emergency-stop monitoring
      Monitors a documented single- or dual-channel emergency-stop circuit.
      Guard-door interlocking
      Monitors an approved safety-door circuit and controls enabling contacts.
      Delayed machine stop
      Uses the documented delayed enabling output where the validated risk assessment requires run-down time.
      Safety-relay replacement
      Restores the exact installed relay after wiring, delay and reset behavior are recorded.
      Read the applicable manufacturer instructions before work. Verify SRB-NA-R-C.35-CH2A-24V, the installed system and every configured field interface before isolation, wiring or commissioning.
      1
      Verify the full SRB-NA-R-C.35-CH2A-24V marking; the supplied catalog does not decode the CH2A suffix.
      2
      Place the machine and its safety function in the authorized maintenance state before relay work.
      3
      Record every input, enabling output, monitoring output, feedback-loop connection and delay setting before removal.
      4
      Confirm the actual nameplate supply and use only the documented 24 V circuit arrangement.
      5
      Wire the emergency-stop or guard-door circuit exactly as defined by the validated safety design.
      6
      Preserve the selected automatic/manual reset behavior and prove the feedback loop before enabling motion.
      7
      Set the delayed enabling output only to the value established by the machine risk assessment and controlled drawing.
      8
      After installation, test channel faults, reset behavior, contact transfer, delay time and safe-state response before release.

      • Which reset method applies to SRB-NA-R-C.35-CH2A-24V?
        The family supports selectable automatic reset and includes a feedback loop; the installed setting must be recorded and validated.
      • Which supply should be used for SRB-NA-R-C.35-CH2A-24V?
        Use the exact nameplate supply. The catalog documents 24 V DC and 24 V AC family variants with their respective tolerances.
      • What contact duty is documented for SRB-NA-R-C.35-CH2A-24V?
        The family data lists 230 V AC / 6 A for an ohmic enabling load, DC-13 at 24 V / 2 A and AC-15 at 230 V / 3 A.
      • Which response times apply to SRB-NA-R-C.35-CH2A-24V?
        The family specification lists a maximum 200 ms pick-up time and maximum 30 ms drop-out time, apart from the intentionally delayed output.
      • What must be tested after replacing SRB-NA-R-C.35-CH2A-24V?
        Prove channel-fault detection, feedback and reset behavior, all enabling contacts, the configured delay and the machine's safe-state response.
