RMS-200 relays

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....


Web relays


The relay will be toggled to the "Normally Open" position as shown below.


Web relay 2


The relays can also be toggled with RMS-200 relay Scripts. Relay scripts are made up of simple commands that control the relays. Complex relay actions can be performed to control your equipment.
For example; starting a generator.


Below is a screen shot of making a relay script to toggle relay 1 on, wait 2 seconds, then toggle relay 1 off again.


Relay script


Each relay can have a name and its actions defined. Below is a screenshot of a relay script that turns a pump on for 30 minutes and then turns it off again.

Relay names


Control of the RMS-200 relays can also be done by using telnet or ssh. Below is an example of using the rmsrelay command to toggle relay 1 on and off.


Telnet relay


Below is an example of reading the status of Relay 1 using the command line interface. Note the relay1, relay2, and relay3 file will contain a "0" when the relay is in the "Normally Open" position, and will contain a "1" when in the "Normally Closed" position.


Relay 3


An example of running a relay script on the command line using the rmsscript program. The example below runs relay Script 1.


Relay script 2


PHP programmers may want to write their own programs to control the relays. Below are two example PHP functions that use the PHP system command to turn relay 1 on and off.
