The 1719-TB6 from Allen-Bradley is an Ex I/O terminal block with 6 poles. It is a screw type terminal block which has been engineered for hazardous area installations. It can be installed on an I/O module in a safe area or in Zone 1/0 or Class I, Div. 1 rated hazardous areas. Terminal blocks, which are made as either screw or spring terminals, are wired to devices in the field and they are connected to the front sockets of the I/O modules through screws which are tightened appropriately. The 1719-TB6 is compatible with the 1719-IJ I/O module which is a frequency counter. The dimensions of the 1719-TB6 are 11.1 x 33.3 x 15.3 millimeters and it weighs approximately 5 grams. The core cross-section of the 1719-TB6 is 0.14 to 1.5 square millimeters. It comes in a blue housing. Unshielded 0.14 to 1.5 square millimeters wire should be used with the 1719-TB6. The torque range for terminal screws is from a minimum of 0.22 to a maximum of 0.25 N-m.

To prevent a discharge which could lead to an explosion, the 1719-TB6 should be protected from electrostatic discharge. It must always be cleaned with a damp cloth and never with a dry cloth. Furthermore, the following precautions should be followed while working with the 1719-TB6: a grounded object should be touched to discharge potential static, an approved grounding strap should be worn, pins or connectors on the component boards should not be touched, a static-safe workstation should be used, and the 1719-TB6 should be stored in a static-safe packaging when it is not in use. The 1719-TB6 is not resistant to sunlight or other sources for ultraviolet radiation.
