FAQs

Q1: What is the primary function of the 133819-01?
The 133819-01 is a 6-channel RTD/TC Temperature I/O Module for the Bently Nevada 3500 Machinery Protection System. It interfaces with RTD and thermocouple sensors to provide accurate temperature readings, enabling temperature monitoring and alarm generation for critical rotating machinery .
Q2: How many channels does this module support?
The module supports 6 independent input channels, each of which can be configured to monitor either an RTD or a TC sensor .
Q3: What is the difference between the 133819-01 and the isolated version?
The 133819-01 is the non-isolated version, meaning it does not provide electrical isolation between the temperature inputs and the rest of the module circuitry. This design makes it more cost-effective and compact compared to isolated versions. The isolated version provides channel-to-channel isolation for applications exposed to high voltages or strong electrical interference .
Q4: What output signal does this module provide?
The module outputs a proportional +4 to +20 mA signal for each channel, with voltage compliance of 0 to +12 Vdc and load resistance up to 600 Ω .
Q5: What are the typical applications for the 133819-01?
Typical applications include turbine, compressor, and generator temperature monitoring, as well as industrial temperature control and alarm generation in the 3500 Machinery Protection System. It is widely used in oil & gas, power generation, and petrochemical industries.
