The Omron G7SA-5A1B DC24 is a force-guided relay with 5 N/O and 1 N/C contacts. The mechanical linkage prevents N/O and N/C contacts from being closed simultaneously. Coil is 24 VDC, the standard control voltage across most PLC and safety-relay output cards. The relay body is designed for either socket mounting (G7SA series socket) or direct PCB soldering, so it fits both panel-wired and board-level designs.
If you are panel-building, the socket route saves soldering time and makes swap-out faster during commissioning or fault isolation. The PCB-mount option saves a socket's worth of DIN-rail width — useful when the panel is tight and every millimeter of rail counts.
