Viking Electronics

Viking RC-4A 4 Relay Network Controller

SKU CH-EYW4-GK87D

Controls four relays and monitors sensor inputs over a network with web-based management and email alerts for up to 99 second timed closures

  • Control four relays remotely via web interface
  • Trigger relays with timed closures from 1 to 99 seconds
  • Receive email or text alerts when sensor inputs change state
  • Link two units so one sensor trip activates relays on the other
  • Manage access with encrypted admin and guest logins

Network-Enabled 4 Relay Controller

The Viking RC-4A provides four independently controlled relays accessible over a network connection. Each relay offers normally open, normally closed, and common terminal strip connections. Users can toggle relays manually or set timed closures ranging from 1 to 99 seconds. A web-based interface allows secure, encrypted login with separate Administrator and Guest access levels.

Installers needing remote switching

This unit suits technicians integrating door strikes, gates, or lighting into IP-based systems. It also fits Viking VoIP phone installations requiring a secure remote relay. The four sensor inputs support email or text notification on state change, and one RC-4A can trigger relays on another across the network. Buyers needing more than four relays or sensor inputs should consider additional units.

Four relays and four sensor inputs

The four relays handle typical low-voltage control tasks such as access control or equipment restart. Timed operations are limited to a maximum of 99 seconds per activation. The four sensor inputs monitor dry-contact devices and report changes via the network. Systems requiring higher contact counts or longer timer durations will exceed the capabilities of a single device.

Questions about this item

What network connection does the RC-4A need to reach its web control page?

The controller connects to a standard Ethernet network so the built-in webpage can be reached from any browser on the same LAN.

Can the four relay contacts switch the same low-voltage circuits I use with older Viking door boxes?

Each relay provides normally open, normally closed and common terminals, so existing low-voltage wiring can be landed directly without adapters.

How do I confirm the relays and sensor inputs are responding after I wire the RC-4A?

Log into the encrypted web interface as Administrator and watch the custom-named relay and input status update in real time when sensors change state.
