BM-TR/IS Thermal Resistance Isolator BM Analog Signal Isolator
The Acrel BM-TR/IS PT100 input analog signal isolator converts PT100 thermal resistance signals into various standard analog signals such as current and voltage. These can be connected to PCs, PLCs, DCS, etc. for industrial control monitoring. Thanks to its high anti-interference capability, long-distance transmission is not affected by other devices. The input and output selection range is wide and the accuracy is high. Optional power supply is available, and guide rail mounting facilitates inspection and installation. Widely used in various monitoring systems for centralized temperature measurement. The module receives input signals from RTDs and outputs proportional 2 kV isolated 4-20 mA signals. It is equipped with surge protection, making it suitable for harsh conditions.
