1.0 Introduction
The Universal RTD Module II (URTDII) is an electronic
resistance-temperature detector accessory for the following
devices:

The URTDII can be used to monitor as many as 12 RTD
inputs, These inputs fall into four groups that consist of: six
motor windings, two motor bearings, two load bearings,
and two auxiliary RTDs.
The URTDII can be programmed to accept any of the fol-
lowing types of RTD inputs:
• 100 ohm platinum
• 100 ohm nickel
• 120 ohm nickel
• 10 ohm copper
The RTD type can be selected for each of the four RTD
groups. For example, The motor winding RTD inputs can
be programmed for 10 ohm copper and the motor bearing
RTD inputs can be programmed for 120 ohm nickel.
The URTDII can transmit its information to a protective
device using a fiber optic link. It can be mounted remotely
up to 122 meters (400 feet) from the protective device
when using the fiber optic link.
The URTDII can also be used as a stand-alone device
that communicates on a Modbus network. A bidirectional
RS485 port is provided on the bottom of the unit.
