Detailed reference description
Six channel 3500/60 (without recorder) processes signals from RTD (resistance temperature detector) and TC (thermocouple).
The 3500/60 monitors temperature or temperature difference, usually for radial or thrust bearing metal temperatures conforming to API670, but also for critical process temperatures such as compressor suction and exhaust temperatures, steam temperatures, motor temperatures and stator temperatures.
The 3500/60 adjusts the input and compares the adjusted signal to user-programmable set points that drive alarm and relay logic in the 3500 relay module. External terminal and internal barrier versions are also available.
The 3500/60 and 3500/61 offer the same functionality, with the 3500/61 providing additional 4-20mA recorder output for each of its six channels.
The 3500/60 and 61 modules offer six channels for temperature monitoring and accept two resistors
Temperature detector (RTD) and thermocouple (TC) temperature input.
