Modules
The modules comprising the 509ITM include:
• RTD Input Module
• CT Input Module
• AC Voltage Input Module
• Tap Position Input Module (required for the 300 Series)
• Potentiometer Input Module
• DC Voltage Input Module
• Current Input Module (required for the 200 Series)
• Dry Contact Closure Module
• Powered Contact Closure Module
RTD Input Module
RTD Input Modules are used for monitoring liquid, ambient, or if used in a heated well,
winding temperatures. The input to the module is either a 10 ohm copper or a 100 ohm
platinum RTD (factory configured).
For measuring liquid or ambient temperatures, the module is scaled over the range of -40 -
120° C. If it is used in a heated well, the scale is -40 - 200° C. When ordering the 509ITM
from the factory, the temperature requirements need to be specified.
CT Input Module
The CT Input Module is used to monitor winding temperatures, winding currents, motor
currents of LTCs, or fan currents. The input to the module is a clamp on the CT, provided by
Qualitrol, which has an input range of 0 - 5 A, 0 - 10 A, or 0 - 20 A, other ranges are
available, and an output of 0 - 0.333 VAC, can be used as the input to the CT Input Module.
If this module is used for winding temperatures, the scaling is in the range of -40 - 200° C;
for anything other than temperature, the range is scalable to a maximum of 99999.9° C.
AC Voltage Input Module
The AC Voltage Input Module is used to monitor any AC voltages under 320 VAC. The input
module works in conjunction with the Qualitrol Voltage Sensor, TRA-600-1, and measures
ranges of either 0 - 140 VAC or 0 - 320 VAC.
The range is scalable to a maximum of 99999.9 VAC.
