Features
* This Temperature Monitoring Relay was designed specially for monitoring abnormal temperatures to prevent excessive temperature increase and to protect equipment. * A relay capacity of 3 A at 250 VAC (resistive load) is provided in a slim body only 22.5 mm wide. An output latch function is also supported. * Settings can be made and functions can be selected using the DIP switch. * Reduce the number of models by using universal-input support for thermocouple or Pt100 sensor input. Selecting Functions and Modes * The following settings are provided: alarm mode (upper limit/lower limit), enable/disable latch, C/F, relay output non-fail safe/fail safe, setting protection. Terminal Wiring with Ferrules * Wire with 2 x 2.5 mm2 solid wire or 2 x 1.5 mm2 wiring ferrules. Third-party Certification of CE Mark Compliance, Certified UL Standard Compliance, and Certified TUV and SUD Standard Compliance

Functions
SV Protection
This function protects (i.e., prohibits changing) the alarm setting, operating method, and modes for the Temperature Monitoring Relay that have been set on the rotary switches and DIP switch. The protection function is activated by pressing the output latch reset button on the Temperature Monitoring Relay for at least 5 s or by turning ON the input to the external input terminal for at least 5 s. The power indicator will flash when the protection is activated. The protection function can be released by pressing the output latch reset button on the Temperature Monitoring Relay for at least 5 s or by turning ON the input to the external input terminal for at least 5 s. The power indicator will light while the protection is being reset.
