DIGITAL THERMOSTAT
DATA SHEET
This product is an on/off temperature alarm unit which in-
puts signals from a thermocouple or thermistor sensor and
transmits a relay contact output when an input signal reaches
the preset alarm level. This thermostat is most suited for
overheat detection in machines, equipments, etc.
FEATURES
1. Highly compact
Front panel having a DIN size of 24 x 48 mm, as lightweight
as 100 g and besides, depth just 85 mm, featuring a space
saving design.
2. A variety of temperature sensors connectable
Because thermocouples (5 types) and thermistors (0 to
100°C) are connectable, measurement within a wide tem-
perature range from low to high can be covered so as to
match your equipment.
3. Measured and Alarm Temperatures Displayable
Alarm set value and measured temperature value can be
checked promptly using the front keys.

4. Alarm point settable in 1°C steps
Temperature can be set in 1°C steps by key operation from
the front.
5. Washable front structure
The front display and operating section has an IP66 water-
proof structure (corresponding to NEMA-4X). This design
allows washing from the panel front.
6. 2 relay contact outputs available
This thermostat is capable of issuing 2 relay contact out-
puts. Therefore, any output of high/low limit pair, 2 upper
limits and 2 lower limits can be selected.
