Remote Device Control
The relay module is a
separate hardware device used for remote device switching. With it you can
remotely control devices over a network or the Internet. Devices can be
remotely powered on or off with commands coming from ClockWatch Enterprise
delivered over a local or wide area network. You can control computers,
peripherals or other powered devices from across the office or across the
module can be used to sense external On/Off conditions and to control a
variety of external devices. The PC interface connection is made through the
module houses two SPDT relays and one wide voltage range, optically isolated
input. These are brought out to screw-type terminal blocks for easy
field wiring. Individual LED’s on the front panel monitor the input and two
relay lines. The module is powered with an AC adapter.
|Using the Relay
Module with Enterprise
|The relay setup screen
in Enterprise allows you to open or close the two switches on the relay
module. The switches can be either latched or set for a timed
period and reset. The Data In option lets you check if the voltage
input is 'on' (5-30 V) or 'off' (less than 5 V) on the module's
Once the relay
options are set you can choose when (or how often) you want the
relay module to be triggered.
When the relay
action is active Enterprise communicates with the relay module via
Enterprise Service module
running on the client. The Service module sends the command to the
relay module and returns the outcome to the Enterprise console.
