The terminal blocks used e.g. by the modules with a higher protection - the C-RQ-0400I, and some other peripheral modules, are screwless (with springs) fixed terminals with a 5mm spacing and the Push-In technology. The technology allows inserting the wire (a solid wire, or a stranded wire with a sleeve) without the use of any tools or another hand; in order to eject the wire, a button above the hole for the wire must be pressed (using a screwdriver or other tool, possibly also a finger). For more detailed parameters of terminals, see the following table:
