SHGVA-PT-401 Explosion-Proof Programmable Thermostats
Product Description
Liquid and gaseous media, surfaces, solid and bulk products can be used as objects of temperature control.
Temperature control is performed using a plug-in PT100/100P sensor (not included). Remote monitoring is provided via an RS-485 Modbus RTU interface.
Advantages
- Temperature control in a wide range from -50 to +600°C with a measurement accuracy of ±1°C;
- Dual indication: digital temperature indication (on seven-segment indicators) and LED status indication;
- Possibility of placing the sensor at a distance of up to 100 meters from the device body;
- Remote monitoring capability based on RS-485 Modbus RTU interface;
- Protection from unauthorized access to set parameters ("Block" mode);
- 4-wire measurement circuit (allows to eliminate measurement errors typical for a two-wire circuit);
- Resistance to electrical interference (due to the use of a thermistor as a measuring channel);
- Simplicity and convenience of connection (the use of push-in terminals does not require additional tools, and it is possible to feed wires into the terminals at an angle of 45°).
