Model SEB (switchboard LED bar graph) can be used as an indicator only with no output; with V/mA or serial input as a remote display); or as an indicator/controller with outputs such as relays, analog out (4 to 20 or 0 to 5 V), RS-232, RS-485, USB, or Ethernet), and power input s f rom 5 t o 32 Vdc or 90 to 265 Vac.
When used as an indicator only, the SEB is only 1 in. on the front panel with no depth behind. Two front-panel potentiometers handle zero and span and configuration is via the RS-232 RJ11 port under the display.
The “controller” version has a 2-in.-deep module plugged in the SEB behind the panel. This module contains the relays, analog outputs, RS-232, RS-485, USB, and Ethernet interface as well as power supplies.
Also available is a 30-Vdc output to power 4-to-20-mA transmitters, which eliminates the need for additional power supplies.
