RTD Module
The RTD (Resistance Temperature Detector) module is an optional remote device that provides RTD
inputs, analog inputs, and analog outputs for generator protection applications.
Features
RTD modules have the following features:
•
12 RTD Inputs
•
4 Analog Inputs
•
4 Analog Outputs
•
Secured Read/Write Access
*
•
Reporting and Alarm Functions
•
Communications via Ethernet or RS-485
* The default password for uploading settings to the RTD module is “OEM” in upper case letters.
Functional Description
A functional description of the RTD module’s inputs and outputs is provided below.
Analog Inputs
The RTD module provides four analog inputs that are user-selectable for 4 to 20 mAdc or 0 to 10 Vdc.
Each analog input has under/over thresholds that when exceeded, trip an analog input protection
element. The label text of each analog input is customizable.
RTD Inputs
The RTD module provides 12 user-configurable RTD inputs for monitoring system temperatures. Each
RTD input can be configured to protect against high or low temperature conditions. The label text of each
RTD input is customizable.
Analog Outputs
The RTD module provides four analog outputs that are user-selectable for 4 to 20 mAdc or 0 to 10 Vdc. A
wide selection of parameters including BE1-11g metered voltages and currents, analog inputs, and RTD
inputs can be configured as analog outputs. Refer to the Programmable Outputs, Remote Analog Outputs
screen in BESTCOMSPlus
® for a full list of parameter selections.
Alarm Contact Functions
The RTD module provides form C (SPDT) alarm contacts that operate when an internal RTD module
failure exists. The contacts also operate when operating power is cycled.
Real-Time Status Functions
The RTD module is equipped with a multi-function LED with the following functions.
•
Slow Flashing - Communications established
•
Quick Flashing - Communications lost
•
Steady On - Power applied
