The 1719-IR4B is a genuine Allen-Bradley Ex I/O RTD input module that comes with 4 channels. With the 1719-IR4B, which belongs to the Bulletin 1719 Ex series, the users have a module that can operate at a voltage rating of 12 Volts DC. The 1719-IR4B comes with an unshielded wire, measuring between 0.14 millimeters and 1.5 millimeters. This I/O module can accept 2, 3, or 4-wire RTD signals as well as field slide-wire sensors. The 1719-IR4B is outfitted with a smart open plus short-circuit line fault detection features, making it a dependable and safe module that users can acquire to take their industrial applications to the next level. The 1719-IR4B’s intrinsically safe inputs have been galvanically isolated, especially from the system power supply and bus terminals. This 4-channel module can operate a supply circuit of 15 Volts or 20 milliamps. The 1719-IR4B should be installed in Zone 2 or Class I (i.e. in a Division 2 area or even a safe area).

The 1719-IR4B has a HART communication feature plus 1 LED per channel. This self-monitoring unit can permit both vertical and horizontal mounting—making it extremely versatile and able to handle a wide range of industrial applications. Even more, the 1719-IR4B can be exchanged for undervoltage, but the area must be nonhazardous. When installing the 1719-IR4B, it is important to observe general procedures to prevent electrical damages. For instance, the users should strictly observe the allowable conductor core cross-section. When installing this unit, ensure that the conductors reach up to the terminal, And if the users are using a stranded conductor, make sure to crimp on the wire end ferrules. Do not pull the cable because the wire can easily become loose from its terminal as well as the protection device and cause an electric shock. So, instead of pulling the cable, pull the terminal. The 1719-IR4B is suitable for use in demanding industrial settings and for time-critical applications.
