Compact and Slim Relay Ideal for
Temperature Alarms and Monitoring
• Excessive temperature increases can be prevented and
abnormal temperatures can be monitored.
• Temperature monitoring in slim design with a width of just
22.5 mm.
• Simple function settings using DIP switch.
• Universal-input support for thermocouple or Pt100 sensor input.
• Selectable output relay: Non-fail safe/fail safe.
• Alarm status identification with LED indicator.
Refer to Safety Precautions for All
Temperature Controllers.
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 × 2.5 mm2 solid wire or 2 × 1.5 mm2 wiring ferrules.
Third-party Certification of CE Mark Compliance, Certified UL
Standard Compliance, and Certified TÜV 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.
