The PNOZ s11 series General Purpose Relay with 2-channel operation via PNOZsigma connector. The contact expansion module is suitable for increasing the number of available contacts. The unit meets the requirements of EN 60947-5-1, EN 60204-1 and VDE 0113-1. The contact expansion module is used to increase the number of instantaneous safety contacts available on a base unit. Base units are all safety relays with feedback loop monitoring. The contact expansion module expands an existing circuit. As the output relays are monitored via the base unit's feedback loop, the safety functions on the existing circuit are transferred to the contact expansion module.

• Positive-guided outputs
• Safe separation of safety contacts from all other circuits
• Plug-in connection terminals (either spring-loaded terminal or screw terminal)
• The safety function remains effective in the case of a component failure
• Earth fault in the input circuit
• Earth fault in the feedback loop
