RMS-300 has 4 latching power relays for remote control of AC powered equipment.
RMS-300 has four latching power relays for remote control of AC powered equipment.
Control of each relay can be done with a web browser. The picture below shows a portion of
the RMS-300 relays web interface. In the picture below all relays are in the default
"Normally Closed" position. By clicking on the relay 1 icon....
The relay will be toggled to the "Normally Open" position as shown below.
The relays can also be toggled with RMS-300 relay Scripts. Relay scripts are made up of simple commands that control the relays. Complex relay actions can be performed to control your AC powered equipment.
Below is a screen shot of making a relay script to toggle relay 1 on, wait 2 seconds, then
toggle relay 1 off again.
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.
Control of the RMS-300 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.
Below is an example of reading the status of Relay 1 using the command line interface. Note
the relay1, relay2, relay3, and relay4 file will contain a "0" when the relay is in the "Normally
Closed" position, and will contain a "1" when in the "Normally Open" position.
An example of running a relay script on the command line using the rmsscript
program. The example below runs relay Script 1.
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.
<?php
