The 92-00938-02 terminal is a display panel or operator interface terminal manufactured by Eaton Cutler-Hammer as part of the Panelmate 92** series. This terminal and other products in the Panelmate 92** product line are specially designed to provide cost-effective and flexible solutions for upgrading traditional hardwired operator control panels. When one serial connection is used with the PLC, this Panelmate 92** unit can be used in place of several individual control devices, including selector switches, analog meters, and pushbuttons. It can also replace indicator lights, thumbwheels, digital readouts, message display units, and all the related wiring as well as PLC input and output modules. The graphics capabilities of Panelmate devices, including the 92-00938-02 operator interface terminal, offer functionalities that used to be performed by the CRT-based devices, but these Panelmate units provide a control capability that CRT-based devices never had.

The Eaton Cutler-Hammer 92-00938-02 operator interface terminal and other IDT Panelmate devices can be used as spare parts for more than 600 hardwired devices. They are economical, even though only a few points can be monitored or controlled at a time. They can provide even more benefits if certain changes are applied to the user control panel. In addition to replacing the traditional panel-mounted controls, controller faceplates, and operator message units, these Panelmate units, including the 92-00938-02 operator interface terminal, provide alarm and data-logging features as well. They also allow for the monitoring and control of critical PLC control actions consistently and they report any abnormal conditions on the hardcopy printer and screen. When using these Panelmate devices, the operators have the flexibility to alter or construct operator controls easily.
