Detailed Feature Overview
This connector includes 48 screw terminals for field wiring. Each terminal accepts wires from 0.5 to 2.5 mm² easily. The 5.08 mm pitch provides adequate spacing for reliable insulation.
A removable coding key prevents inserting the wrong connector. You can set this key to match a specific I/O module slot. Consequently, you avoid costly wiring errors during maintenance.
The integrated strain relief secures your incoming cable bundle. This feature reduces stress on individual screw terminals significantly. You can route cables from either the bottom or top side.
Installation and Compatibility
Siemens 6ES5497-4UB31 fits all S5 I/O modules with 48-pin interfaces. Push the connector straight onto the module until it locks. Use a 3.5 mm screwdriver for terminal tightening.
