ProSight DIN Mount Isolated RTD Temperature Transmitter 4–20mA
ProSight DIN Mount Isolated RTD Temperature Transmitter 4–20mA is a programmable mounted temperature transmitter with universal input (thermocouple, RTD, mV, resistor) and isolated analog or digital outputs. Designed for seamless integration with PLC, DCS, and industrial automation systems.
The ProSight DIN Mount Isolated RTD Temperature Transmitter 4–20mA is a versatile industrial signal conditioning and transmission device designed to receive temperature and electrical measurement signals from field sensors and convert them into standardized output signals for monitoring and control systems.
Despite its product name emphasizing temperature and resistor measurement, it supports a broad range of programmable inputs, including thermocouples, RTDs, linear resistance, and millivolt signals. This flexibility allows a single transmitter platform to be configured for different measurement requirements.
The unit is designed for 35 mm DIN-rail installation and uses pluggable terminals, making it suitable for mounting inside control cabinets, automation panels, instrumentation enclosures, and industrial electrical systems.
It is available in configurations with:
- 1 input / 1 output
- 1 input / 2 outputs
- 2 inputs / 2 outputs
Depending on the selected configuration, output options include 4–20 mA, 0–10 mA, 0–20 mA, 0–5 VDC, 1–5 VDC, 0–10 VDC, relay output, and RS485 Modbus-RTU communication. An LCD indicator is also available as an option.
How Does it Work?
The ProSight DIN-Mount Isolated RTD Temperature Transmitter 4–20mA operates as an interface between field sensors and industrial control equipment.
- Sensor measurement – A thermocouple, RTD, resistor, or mV sensor produces an electrical signal corresponding to the measured temperature or process variable.
- Signal input – The sensor signal is connected to one of the MSC90T's configured input channels.
- Signal processing – The transmitter processes the input according to the selected sensor type and measurement range.
- Signal isolation – The input, output, and power circuits are electrically isolated, helping reduce ground-loop effects and electrical interference.
- Signal conversion – The processed measurement is converted into the selected analog, relay, or digital communication output.
- System transmission – The output is transmitted to a PLC, DCS, SCADA system, controller, indicator, or other compatible industrial equipment.
- Optional digital communication – Where RS485 is selected, the transmitter can communicate using the Modbus-RTU protocol.
This arrangement provides a practical method of converting and isolating field sensor signals before they reach sensitive control and monitoring equipment.
