URTDII Module Interface
URTD
Principle – General Use
The optional Universal Resistance-based Temperature Detector II (URTDII) Module provides temperature data to the
protective device up to 12 RTDs embedded in the motor, generator, transformer, or cable connector and driven
equipment (see Eaton I.L. IL02602013E). The temperature data will be shown as measured values and statistics in the
Operating Data menu. In addition, each channel will be monitored. The measured data provided by the URTDII
Module can also be used for temperature protection (please refer to the Temperature Protection section).
The URTDII conveys multiplexed temperature data back to the relay via a single optical fiber. The URTDII may be
mounted remotely from the protective device. The fiber optic connector is located on the
X102
terminal
of the
protective device.
Consider the benefit of mounting the URTDII module away from the protective device and as close to the protected
equipment as possible. The big bundle of RTD wires to the protected equipment becomes much shorter. The URTDII
may be placed up to 400 ft (121.9 m) from the protective device with the optical fiber connection. Note that the URTDII
will require a power supply connection at its remote location.
Connect a suitable source to the power terminals J10A-1 and J10A-2 on the URTDII module. Connect any of the
Shield terminals to a non-current-carrying safety ground. It is recommended to have a ground connection on both sides
of the unit.
