Control Your Equipment By Telephone Line or Internet - Touch Tone Controlled Relays

Relay Control Unit

Intelligent DTMF Controlled Relay Units 
for Single Device Control, Dual Device or Access Control applications

 

Our New Intelligent RCU devices replace our popular RTA1 and RTA2 devices that have been in use for over 20 Years. 

Our RTA devices are still available if a simpler and less expensive device is sufficient for your application, or where an additional RTA or a replacement RTA device is required.

1. Analogue, FXS or ATA connection solution

  • Models RCU1 and RCU2 are designed to connect to ANY of the following Telephone Line Connections :
     

*  PSTN Lines    PBX Analogue Extensions   FXO Ports   *   FXS Ports    
* ATA Output   * Cellular Gateway Output   *  A dedicated Access Control Line

 

2. Direct IP or Cloud connection solution

  • Model RCU-SIP  is designed to connect ANYWHERE on an IP PBX Network :
     

*  Network Point    Internet Modem   Internet Router   *   Network Switch    

*   Any point for an IP-PBX     *   Any point for an IP-Cloud-PBX

 

RCU-SIP connect as a SIP Extension by DHCP. Our supplied PC program provides you with its IP and MAC address and will allow you to set up its Extension Number, SIP Server IP Address and if required a username and password.

A Static IP address can also be easily set up via our Browser Admin Panel, together with full control over Codec and other settings.

SINGLE UNIT OPERATION

 
 
Any RCU model will allow you to remotely control one or two electrical devices by dialing an Extension or Phone Number and entering a user set DTMF code.
 
With RCU you can Open a Gate or Door, or with the correct Accessories you can Turn On or Off a Light, or Reset a PC or Server.
 
 
MULTIPLE UNIT OPERATION
 
You can also use Multiple RCU units together to control Multiple Devices or set up sophisticated Access Control applications.
 
 
 

There are 3 Models, which can be used individually or in any combination :

 

• Model RCU1 – Has a Single Dry Contact Relay (rated at 1A) that can be programmed to respond to any 1-4 digit DTMF Code and which can be programmed to Toggle On/Off or Close for a period of 01-99 seconds.
 

• Model RCU2 – Has Two Dry Contact Relays (rated at 1A) each of which can be programmed with its own Code and Relay Closure time. 


 Model RCU-SIP –  Is designed for Direct Connection to ANY Network Point. It Has Two Dry Contact Relays (rated at 1A) each of which can be programmed with its own Code and Relay Closure time.

APPLICATIONS

Application Example 1

 
Asimple application would to connect an RCU1 to an Analog Extension and program the Relay1 to respond to the DTMF code 11. The closure time of the relay can then be set to 15 seconds.
 
Then to Open an Electric Door, the user would just dial the extension number to which RCU1 is connected and then when RCU1 answers, they would press 11
 
 
 
Application Example 2
 
 
A more complex application would to be to ADD another RCU to this same line, connected in parallel.  In this example an additional RCU2 is used, which has 2 separate Relays, each which can have its own DTMF activation Code and Relay Closure time. Relay 1 has been programmed for DTMF 22 and its relay will for 30 seconds. Relay 2 has been programmed for DTMF 33 and its relay is programmed to close for just 2 seconds, for a momentary closure.
 
Now a user can dial the same extension number, wait for RCU to Answer (all will answer) and then press 22 to allow access to a specific Elevator Floor (for up to 30 seconds) or press 33 to Open a Boom Gate.
 


 

Other Applications

For even more Complex Applications, Multiple RCU’s (any combinations of RCU1’s and RCU2’s) can be connected to the same Telephone Extension (or line) and every relay can be programmed with its own unique code and relay closure time.

Then a user can call the extension number and either dial an individual relay code, or even enter a number sequence where several codes are dialled to command multiple relays to respond.

For example pressing 12345, could control 5 separate relays, each controlling its own device or access. DTMF 51423 could be dialled to achieve the same result, as each RCU relay can be set to only look for its own unique code in a sequence.

 

 

Accessories

POWER CONTROL UNIT

The Power Control Unit (PCU ) provides for completely safe and automatic connection or disconnection of a 240V (110VAC to 250VAC, 10 Amps) electricity supply to all attached equipment, when used in conjunction with an RCU or RTA device. This unit is designed for quick and easy user installation. Simply connect the POWER PLUG of the PCU to your electricity supply and the POWER SOCKET to your electrical equipment. The PCU  then connects direct to the RCU or RTA with a supplied 'curly cord adaptor'.

PCU is available in two models.

  • PCU -1 is configured in a NORMALLY ON configuration, so that your equipment will be switched ON, unless commanded by an RCU or RTA device.
     
  • PCU -2 is configured in a NORMALLY OFF configuration, so that your equipment will be switched OFF, unless commanded by an RCU or RTA device.
