The MS220K2 monitors 2 PTC-
resistor sets at the same time. If
a temperature rise occurs in one
set, the appropriate output relay
releases.
With this relay, 2 PTC-sets can
be independently monitored on
only 22.5 mm space
2 PTC-resistor sets, each 1...
6 PTC resistors
output relays 2 x 1 change-
over contact (co)
LEDs for operation and
alarm
