Features:
- ELAN-branded safety relay identified by the complete SRB-NA-R-C.33-24V nameplate.
- Control supply is 24 VAC/DC at terminals A1 and A2.
- The label separates IP20 terminal protection from the IP40 housing rating.
The full suffix and front terminal diagram define the wiring arrangement that must be retained during legacy safety-circuit service.
Nameplate contact and fuse ratings establish electrical limits for the connected outputs rather than a general rating for any replacement relay.
Commissioning remains a functional safety task covering inputs, feedback, reset behavior, connected loads, and the expected safe-state response.

Important Notice: Other accessories, manuals, cables, calibration data, software, and related items are not included unless identified in the stock item description.
- Rated control current is marked 125 mA with a 24 VAC/DC operating supply.
- Rated insulation is 250 VAC with a 4 kV/2 marking on the front label.
- Contact ratings include DC-13 24 VDC/6 A and AC-15 230 VAC/6 A.
- UL main-output ratings are stated as 230 VAC/4 A and 24 VDC/4 A.
- Apply the 24 VAC/DC control supply at the labeled A1/A2 terminals.
- Map each safety input and jumper exactly from the installed front circuit diagram.
- Retain the feedback and reset arrangement before disconnecting the existing relay.
- Keep output-terminal assignments and connected loads tied to the recorded channel functions.
- Retain fuse F2 T0.125 A/250 V and internal fuse F1 T0.25 A/250 V in the service record.
- Use IP20 for terminal protection and IP40 only for the housing boundary.
- Compare connected output loads with the applicable contact-rating category before energization.
- Test the safety inputs, feedback, reset path, and safe-state response under the approved site procedure.
- Maintenance of installed safety circuits built around the exact .33-24V terminal arrangement.
- Legacy relay replacement where the 24 VAC/DC supply and nameplate contact limits remain unchanged.
- Machine-safety service requiring documented feedback, reset, and safe-state functional validation.
