Digital Loggers DIN IV Web Controlled Relay Operation

Digital Loggers DIN IV Web Controlled Relay Operation


The Web Controlled DIN Relay 4 allows the user to control and reboot equipment securely from a web browser or via program control. The internal web server is accessible from any standard web browser (a keypad and LCD are also available for local control). It provides 8 single-pole double-throw (SPDT) channels of relay output in a compact DIN rail mountable package.

Web Controlled DIN Mount Relay


Quick Setup Guide:
  1. Connect to the network using an RJ-45 cable (current model allows for Wi-Fi). The default IP address on the relay is 192.168.0.100 and this should be compatible within your LAN.
  2. Apply power to the relay. The LCD will illuminate. The DIN 4 Relay accepts 12-28 VDC and draws 5W maximum.
  3. Enter 192.168.0.100 in your web browser address bar. If the login page doesn’t appear: - Use a direct cable connection (temporarily bypassing any switch or router) then add an IP compatible with the relay such as 192.168.0.50. Revert to DHCP or a combination of DHCP and static IPs once the browser login page appears to allow for internet access. Before adding an IP, close programs and browsers. 
  4. Login using the default username, admin (lower case). Enter the default password, 1234.
  5. Use the setup page to add relay names or change the IP.
  6. Set the recovery mode for safety after a power failure. The recovery mode controls default relay settings after power is restored.
  7. Change the password to improve security.
A more detailed manual on setting up your device can be found here.
An ohmmeter is handy for testing the relay before attaching equipment.
When powered, the relay performs a Power on Self-Test (POST) to ensure reliability. It will then look for a DHCP server. If none is found, the relay defaults to the fixed (static) IP address set on the setup page. This is shown on the LCD. If enabled, script execution starts after POST. The relay may then be operated via the web. To access the relay, simply enter the IP address (192.168.0.100) in the URL field of your web browser.
Each of the 8 SPDT contacts is independently controlled by a logic-level input signal. The relays are rated for up to 10A at 120VAC and are fused at 12A. A programmable delay timer allows relays to be switched on in sequence, rather than simultaneously. Many loads draw more power when they are initially switched on. Sequencing prevents circuit overloads when loads devices are attached to a single circuit.

Overall, the Digital Loggers DIN Relay 4 is a versatile and reliable device that can be used in a wide variety of industrial and automation applications to switch high voltage and high current loads on and off. The DIN relay is a low cost, easy-to-use alternative to PLCs and PC-based controllers.
