SZ Controller Carrier specifications

Installation notes

• The SZ Controller Carrier installs on vertical T-type DIN rails.
• Redundant SZ Controllers plug into the slots on the SZ Controller Carrier.
• The SZ Controller Carrier provides redundant 24 VDC power for the SZ Controller. Refer to Figure: Powering the SZ Controller Carrier.
• The SZ Controller Carrier houses a primary and secondary Ethernet Isolation Port (EIP). Each EIP consists of an Area Control Network port for connections to the DeltaV Area Control Network, a Safety Network port for connections to the Local Safety Network, and port activity LEDs. For standalone safety systems, the Area Control Network ports function as redundant Modbus TCP ports. Each EIP has a port activity LED. The EIPs are removable. To remove an EIP, depress the button next to the EIP and push it out of the carrier. Refer to the images following the table.
• Screw terminal connections on the carrier allow an external power source to be connected to backup the real-time-clock on the SZ Controllers for power outages greater than 24 hours. If these connectors are used, the power source must meet the requirements in the following table.
