The Relays

FIGURE 6

RMS-200 has three power relays for remote control of AC/DC powered equipment. Each
relay has a manual override button that can toggle the relay; useful for on-site testing.
Each relay also has a jumper shunt connector that allows the relay to be engaged
manually for hands free testing.

Control of each relay can be done with a web browser. The picture below shows a portion
of the

RMS-200

relays web interface. In the picture below all relays are in the default

"Normally Closed" position. By clicking on the relay 1 icon…
