Control Relay Contacts Across a Local Area Network

Features

The 

RC-4A

Network Enabled Relay Controller provides

networked control of four relays via an easy-to-use web
interface.  The same interface can be used to check the
status of four contact closure inputs. Relays can be
toggled on or off, or  activated for a length of time.

The 

RC-4A

can be configured to work as a remote relay

for Viking VoIP series phones, controlling door strikes
and gates when a remote relay is required for security
reasons.  It can also be programmed to send an email or
text message in response to a change in one or more of
the sensor inputs.  Two 

RC-4A

’s can be set up so that

activity on a sensor input of one unit will automatically
send a message across the network to activate one of
the relays on the other unit.

Two levels of user access permit selected users to have
full operational and programming rights while others have
operational control but not programming capability.

• Terminal strip connections for normally open,

normally closed, and common for all four relays

• Relays can be toggled or timed closures of from 1

to 99 seconds can be activated

• Terminal strip connections for all four sensor

inputs

• Notification by email or text message of

sensor input state change

• Can be used as a secure remote relay for

Viking VoIP series phones

• Remote Interaction:  sensor change on one

RC-4A triggers relay activation of a second
RC-4A across network

• Ready-to-use webpage control interface
