The IS230SNRTH2A RTD input module is a commonly used input device in industrial automation systems, mainly used to process temperature input modules. It can measure temperature through thermistors, thermocouples, or thermistors. The RTD input module can provide terminals I+and I – current for resistance measurement, and the current flows through the resistance to measure its voltage. This type of module typically has multiple isolated differential RTD input channels, and each channel supports different types of resistors such as platinum, nickel, nickel iron, copper, etc., while also being compatible with direct resistor input.
Taking GE Fanuc General Electric’s IC695ALG508 Resistance Temperature Detector (RTD) input module as an example, it is part of the PACSystem RX3i Programmable Automation Controller (PAC) platform and has eight isolated differential RTD input channels. When configuring RTD analog inputs, users can choose different RTD types and wire systems, such as 4-wire, 3-wire, or 2-wire resistors, as well as corresponding wire systems for thermistors, to obtain high-precision measurement results.
Overall, the IS230SNRTH2A RTD input module plays an important role in industrial automation systems, capable of accurately and reliably measuring temperature and providing critical data for industrial process control and monitoring.
The IS230SNRTH2A RTD (Resistance Temperature Detector) input module plays a crucial role in industrial automation systems, used to process temperature related input signals.
The following are some of the main features of the RTD input module:
Signal compatibility: The IS230SNRTH2A RTD input module supports multiple signal inputs, including voltage, current, and resistance signals. Specifically, it can process current signals such as 0-20 mA, 4-20 mA, voltage signals of+50mV,+150 mV, 0-5 V, 1-5 V, 0-10 V, and resistance signals ranging from 0 to several thousand ohms. In addition, it also supports various types of RTD sensors and thermocouple inputs.
Power consumption and power: IS230SNRTH2A RTD input modules typically have lower power consumption, with some modules having a maximum power consumption of 5.4 watts. The internal rated power varies depending on the specific model, but generally within the range of hundreds of volts, the corresponding current is a few milliamperes.
Channel configuration: Input channels are usually divided into multiple groups, each containing multiple channels. For example, some modules have 2 groups of channels, each with 4 channels, for a total of 8 channels. This configuration enables the module to process multiple input signals simultaneously, improving the parallel processing capability of the system.
Working principle: The working principle of the IS230SNRTH2A RTD module is based on the relationship between the resistance value of metal resistance components and temperature. When the ambient temperature changes, the resistance value of the metal resistance will also change accordingly. By measuring the resistance value and based on its relationship curve with temperature, the current temperature value can be accurately obtained.
Protection and authentication: Some advanced RTD input modules also have various protection measures, such as transient protection, continuous input protection, etc., to ensure that the module can still operate stably in harsh environments. Meanwhile, these modules typically undergo various certifications such as CSA, FM, CE, and ATEX to meet the safety and compliance requirements of different countries and regions.
