The K8AB-TH is a temperature-monitoring relay that embodies both
temperature-alarm functionality and simple ON/OFF temperature
control. The unit is designed specifically for monitoring abnormal
temperatures to prevent excessive temperature increases and
to protect equipment. It comes in a slim housing with a width
of just 22.5 mm suitable for DIN-rail or direct panel mounting.
Settings are selected by DIP switches, making the K8AB-TH easy
to configure. The alarm threshold is set using rotary switches

on the front, allowing the alarm point to be easily checked at
a later time. The unit features multiple inputs with support for
both thermocouples and Pt100 sensors. For the alarm output,
a change-over relay is provided and, in contrast to many other,
comparable, monitoring relays, the K8AB-TH also embodies an
output latch function with (front button) latch reset, SV protection
and the choice of fail-safe/non-fail-safe relay operation.
