To prevent users from making a mistake and installing this terminal to an unsuitable module, the coding pins are applied. This securing accessory is pushed into the grooves visible from the front side of sockets on the I/O modules. This is a simple way to implement an exclusive assignment between I/O modules and their belonging screw terminal blocks. The dimensions of this 8-pin terminal are 40.9 millimeters by 15.3 millimeters by 11.1 millimeters (1.61 inches by 0.60 inches by 0.44 inches). The 1719-TB8 is connected or detached in a simple manner for the easy commissioning and maintenance of distributed I/O systems. Through these blocks, ground wires are connected, so these screw terminal blocks play a really important role when it comes to personal safety and equipment safety. The input holes on the terminal are clearly marked with numbers from 1 to 8.
