FAQ's of Terminal Block Type PT Transmitter With Isolated Single Output:
Q: How do I install the Terminal Block Type PT Transmitter on my DIN rail system?
A: To install the transmitter, simply snap the module onto a standard DIN rail in your control panel. Use the screw terminals to connect input (RTD sensor), output (4-20 mA loop), and power supply (18-36V DC), ensuring all wiring adheres to the specified configuration.
Q: What advantages does galvanic isolation provide in this transmitter?
A: Galvanic isolation up to 1500V AC protects your system from ground loops and electrical interference, ensuring accurate and stable signal transmission between input, output, and power circuits. This is essential for industrial environments where electrical noise may be present.
Q: When is it appropriate to use this PT transmitter for temperature measurement?
A: This transmitter is suitable for precise temperature monitoring in HVAC systems, manufacturing plants, and process industries, especially where PT100 RTD sensors are required. Its high accuracy and wide temperature range (-200C to +600C) make it ideal for critical applications.
Q: Where can I use the Terminal Block Type PT Transmitter in industrial applications?
A: The transmitter can be deployed in control panels, distribution boards, or automation cabinets for temperature monitoring or process control, commonly found in chemical plants, power stations, and food processing industries across India.
Q: What is the process for connecting a PT100 RTD sensor to the transmitter?
A: Connect the PT100 RTD sensor to the designated input terminals following your sensor type (2, 3, or 4-wire). Refer to the transmitter's wiring diagram to ensure correct terminal placement, then connect the output (4-20 mA) and the 24V DC (18-36V) power supply.
Q: How is the transmitter's output configured and what is its usage benefit?
A: The output is an isolated 4-20 mA analog signal that can be connected directly to PLCs, recorders, or display panels. This standard signal format ensures long-distance transmission with minimal loss, providing reliable temperature data for process control.
Q: What protection and durability features does this transmitter offer?
A: With an enclosure rated to IP20 and constructed from flame-retardant polyamide PA, the transmitter is protected against dust and accidental contact. It operates effectively in temperatures from -10C to +70C and humidity up to 95% RH, non-condensing.
