The 1426-DM Module is an Allen-Bradley PowerMonitor 5000 Touchscreen Display Module and a Human Machine Interface (HMI) that is specifically designed and built by Allen-Bradley to serve as the operator’s dashboard where the real-time information from one, two, or three PowerMonitor 5000 or PowerMonitor 1000 modules can be accessed through several factory-installed applications. The Allen-Bradley 1426-DM Touchscreen Module comes as a 4-inch display module that shows important electrical data such as the peak voltages, reactive power, and the power factor of a given installation that is received from up to three PowerMonitor modules. It can be supplied with power from a 600 Volts AC utility line and it has a current rating of 5 Amps, a rated frequency from 40 to 75 Hertz, an accuracy rating of 0.2% and a built-in 4-digit relay output that enables the unit to activate alarms or start safety-related operations.

The Allen-Bradley 1426-DM PowerMonitor 5000 Touchscreen Display Module is designed for panel mounting in power monitoring or control systems, especially in remotely located operation panels. By centralizing the vast amount of information coming from each of the individual PowerMonitor modules in the system, the operators will have quick access to every single electrical parameter under their supervision at their fingertips. Environmental protection against high temperature, humidity, corrosive atmospheres, and dust should be provided by the users, either by installing the 1426-DM Touchscreen Display Module in a suitable enclosure or by installing it inside a climate-controlled room. Only properly trained, certified, and authorized technicians should be allowed to perform service procedures on these units to guarantee the best operational results.
