Product Description
Product Overview
- Manufacturer: Bently Nevada
- Model/Part Number: 3500/61 133827-02
- Description: RTD/TC Non-Isolated I/O Module External Terminations
Specifications
Inputs
- Signal Type: Accepts 1 to 6 RTD (Resistance Temperature Detector) or TC (Thermocouple) transducer signals.
- Input Impedance: 10 MΩ for each lead input.
Power Consumption
- 3500/61 Module: Nominal consumption of 9 watts.
Transducers and Isolation
- System Isolation: 500 Vdc
- Channel-to-Channel Isolation: 250 Vdc
- Notes: Isolation is required only for fault scenarios; these voltages are not present on the I/O module inputs under normal conditions.
Outputs
-
Front Panel LEDs:
- OK LED: Indicates when the Temperature Monitor is operating properly.
- TX/RX LED: Indicates when the Temperature Monitor is communicating with other modules in the 3500 rack.
- Bypass LED: Indicates when the Temperature Monitor is in Bypass Mode.
Alarms
-
Alarm Setpoints:
- Alert and Danger setpoints are adjustable using software configuration.
- Range: Adjustable from 0 to 100% of full-scale for each measured value, unless limited by the sensor's range.
- Accuracy: ±0.13% of the desired value.
- Supports both under and over alarm setpoints.
-
Alarm Time Delays:
- Alert: 1 to 60 seconds in 1-second intervals.
- Danger: 1 to 60 seconds in 0.5-second intervals.
Measured Values
- Description: Provides temperature measurements to monitor the machine.
