Question:        What's new in this product?

Answer:           In our newest model ( DIN Relay II), with serial numbers DIN22000 and higher, we've added these features:

• Relay anti-chatter protection.  Maximum relay switching frequency is limited to 2Hz for safety and longevity.
• Variable coil current control.  Relay holding and pull-in currents are regulated for improved efficiency.  Power consumption has been reduced by more than 40% from earlier models.
• Watchdog supervisor.  We've added a second processor which continuously monitors the microcontroller and reboots it gracefully if necessary.
• Increased memory. Non-volatile memory has been increased from 16kb to 256kb.  No memory expansion board is required for script storage.

Question:        What are the contact ratings?

Answer:           All eight internal T-90 Relays have the following ratings:

Relays are RU and CE component approved, and rated at 250,000 operations MTBF at 50% load.  Case terminals are rated at 12A.  Only stranded wire of appropriate gauge should be used.  Terminals must be well torqued.  It is wise to recheck torque after completing the installation.  Heavy traces and gold plating are used to minimize internal resistance between the terminals and relay contacts, typically 25m Ohms, so internal contact power dissipation is not normally a consideration. For maximum flexibility, relay contacts are unprotected.  For high current inductive switching, consider adding an external snubber circuit to extend contact life.

Question:        What are the power requirements?

Answer:  The relay dissipates an absolute maximum of 5W during switching with all relays on.   Power dissipation decreases with input voltage due to the use of an efficient switching power supply. Typical dissipation with relays off is 2W.  Although the case is well ventilated, ambient air temperature should not exceed 135ºF for maximum reliability.  Surges over 40V P-P may damage the internal regulator.  Add an external MOV or other protection device across the power input terminals in noisy environments.  Power consumption below does not include any load on the +5V accessory output.  We are working hard to make this the most efficient product in its class.

 The +5 output is protected by an auto-resetting polyfuse.  Overloading this output will thermally shut down the polyfuse.  Remove the load and allow 60 seconds for the fuse to reset if this occurs.

Question:        Can I invert AutoPing to use NC contacts?

Answer:           For safety reasons and to prevent support issues, we have not implemented an "invert relay" function in either the web UI or AutoPing.  You can drive the relays in reverse by:

• Setting up a script to turn a relay -on- in the event of an AutoPing failure.  For example  Line 2:  "ON 1"
• Use the autpoing event to trigger the script (enter the line number ie 2 of the script for that Autoping IP).

Question:        What are the mounting dimensions and physical size?

Answer:           Mounting holes are located on 5.308 x 1.968” centers.   Download a complete drawing here.

• Press and hold the reset button for 5 seconds to reset the network settings, user name and passwords.

The default master login is "admin" and default password is "1234".  This procedure resets the admin login and IP address and lockout, but doesn't affect outlet names and links.
