Rated 4 out of 5 by RobertB from It really works! I purchased a couple of these to keep a piece of equipment from overheating. They worked as expected and are keeping the machine safe and the users informed as to the status.

Questions & Answers

What is wired into pins 3&4 (Input)? Is this simply a relay contact to kill the power to my process?

Asked by: Charles1013

Thank you for your inquiry. These input terminal are used for an external reset switch for the alarm condition.

the NC relay output measured closed for continuity with no power applied -- as soon as i applied 120v to power supply connections the NC went open?

Asked by: dan o

Thank you for your inquiry. These are programmable controllers which have the relay switch states based on the conditions that the user selects in the programming.
