Allen Bradley 1719 Ex I/O modules 1719-TB8SX2

The Allen-Bradley 1719-TB8SX2 is a 16-pole terminal block. It is part of the 1719 Ex I/O product range. The 1719 Ex I/O modules are designed for use in hazardous areas where there is a risk of explosions. The construction type of the 1719-TB8SX2 is the spring terminal type of construction. It is available in a blue housing which weighs 5 grams. The following are the terminal block dimensions: 12.4 millimeters in height, 40.9 millimeters in width, and 20.8 millimeters in depth. The core cross-sectional area of the 1719-TB8SX2 is from 0.14 to 1.5 square millimeters. Unshielded conductors (0.14 to 1.5 square millimeters) should be used with the 1719-TB8SX2. The torque range for the terminal screws is 0.22 to 0.25 N-m.

1719-TB8SX2

The Ex I/O 2x8 Pole Spring Terminal module has 16 poles and a terminal screw torque of 0.22 to 0.25 N-m. It has an unshielded wire type. The size of the wire is between 0.14 and 1.5 millimeters square

The 1719-TB8SX2 is compatible with the following modules: the 1719-CF4H, which is a 4-channel HART analog module, the 1719-IF4HB, which is a 4-channel analog input module, the 1719-I4B, which is a 4-channel RTD input module, the 1719-IT4B, which is a 4-channel thermocouple input module, and the 1719-IBN8B, which is an 8-point digital input NAMUR module. The coding pin for the 1719-TB8SX2 is the 1719-CP pin. Coding pins provide unique assignments between I/O modules and terminal blocks. Coding pins are pushed into the grooves provided in the front sockets of the I/O modules. The use of coding pins prevents terminal blocks from being mistakenly plugged into another I/O module. Terminal blocks such as the 1719-TB8SX2 are connected to field devices and attached to I/O modules through screws which are tightened as per the recommended torque values. Terminal blocks are available either as spring or screw terminals.
