DIGITAL THERMOSTAT DATA SHEET This product is an on/off temperature alarm unit which inputs 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. PAS3 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 temperature 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 waterproof 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 outputs. Therefore, any output of high/low limit pair, 2 upper limits and 2 lower limits can be selected. SPECIFICATIONS Specification Number of inputs: 1 Input signal and measurable range: Refer to Table 1.
