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.
