Bently Nevada 135785-01 | 3500/93 Display Unit, non back lighted

Overview

The Bently Nevada 135785-01 3500/93 Display Unit is an essential component designed to provide local or remote visual indications for all data from the 3500 Machinery Protection System. It meets the requirements of American Petroleum Institute Standard 670 and displays crucial system information, such as system events, alarm events, and data from various modules, including channels, monitors, relay modules, Keyphasor modules, and tachometer modules. For applications requiring a backlighted display, an external power supply is needed, with options for both 115 Vac and 230 Vac connections.
