Silver Series EM Operator Interface Terminal
Watlow Offers the Silver Series Operator Interface Terminal
Give Your System an Easy-To-Use Interface with E-Mail Messaging
The Watlow Silver Series EM is a rugged, touch-screen operator interface terminal (OIT) available in three sizess (4.3, 7 and 10 inch diagonal display sizes). It supports a full set of features including serial and Ethernet communications with multiple controllers, e-mail messaging, universal serial bus (USB), data logging, flexible password security and multiple language support. The small bezel size and nominal two-inch depth make mounting in tight spots easy.

The Silver Series EM programming software, EZwarePlus, is easy to use and features a large variety of built-in screen objects that makes it powerful. When creating screens, the user can call upon extensive graphics libraries, import custom graphics and add numeric displays, entry fields, analog meters, bar graphs and trend graphs with just a few mouse clicks. Screen objects are highly customizable and the user can create libraries of their own objects for repeat use. The online simulator and the Ethernet and USB ports make testing and downloading fast. The EZwarePlus screen editor is part of the EZware Plus software suite and is available as a FREE download on and on the CD-ROM on the accessories list.

The Silver Series EM OIT paired with Watlow® controllers is the perfect solution for your industrial process or machine control application.

  • Saves time by exporting data to Excel-compatible comma separated value (CSV) files
  • Improves process understanding by allowing live and historical data to be viewed on the OIT

Alarm and event e-mail notification, monitoring and recording:

  • Reduces downtime by helping troubleshoot equipment and processes
  • Simplifies troubleshooting by recording time and date-stamped alarm and event history
  • Organizes and prioritizes alarms and events in up to 255 categories and 4 priority levels

Recipe management:

  • Reduces errors by automating process setting changes

Offline and Online Simulation:

  • Speeds up development by making it faster and easier to test projects
  • Allows more fine-tuning of interfaces by speeding up iterations

Time or Trigger-based data exchange:

  • Simplifies integration by allowing the OIT to copy data from one controller or OIT to another

Internal, piezoelectric buzzer:

  • Provides audible alarms and key chirp

Two-year warranty

  • Provides product support and reliability

Screen object password security with programmable hierarchy and multiple users:

  • Prevents errors and tampering by allowing only authorized users to access restricted items on the screen
  • Allows flexible hierarchies by letting the developer assign each screen object to any of 12 groups and grant each user access to selected groups
  • Provides password protection for upload, download and access to local setup
  • Supports up to 127 users

Screen object invisibility and/or interlock control:

  • Prevents errors by guiding operators
