Temperature Monitoring Relay

K8AB-TH

CSM_K8AB-TH_DS_E_2_1

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.
