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

MP4000 EMR4000
FP6000 EMR5000
IQ1000II ETR4000
ETR5000
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.

3.1 Programming the Universal RTD Module II
The URTDII must be programmed for the type of RTDs that
are being monitored. A DIP switch assembly on the module
enables programming for the specific application. Figure 2
shows the arrangement of the DIP switches in the assem-
bly. They provide four selection groupings that you must set
during installation.
As Figure 2 shows, the DIP switch assembly contains eight
two-position slide switches that are set in combination.
Each switch is set to ON or OFF by sliding it back and forth.
When facing the DIP switches, slide them:
• Toward the FRONT of the unit for the ON position, and
• Toward the REAR of the unit for the OFF position.
Figure 3 shows a side view of a single slide switch, and
how it is set to ON and OFF.
Observe the ON and OFF designations on the DIP switches
shown in Figures 2 and 3.
Always look for the ON and OFF designations on the ote:N
hardware or printed circuit board to be sure you are
setting the switches correctly.
DIP switch ON and OFF settings are shown in Table 3.

3.2 RTD Wiring
Each RTD must be wired to the URTDII, as shown in Figure
4. The following guidelines must be observed:
Use only one type of RTD (10 ohm copper, 100 ohm nickel,
100 ohm platinum, or 120 ohm nickel) for each RTD group:
motor winding, motor bearing, load bearing and auxiliary.
For example, you cannot monitor one 10 ohm copper motor
bearing RTD and one 120 ohm nickel motor bearing RTD.
However, you can monitor 10 ohm copper winding RTDs
and 100 ohm nickel motor bearing RTDs.
1. Use #18 three-conductor, stranded, twisted, copper wire
to connect the RTD to the URDTII.
2. Connect three conductors from the RTD to the URTDII.
(Two return wires must be connected together). Where the
motor has only two leads from the RTD, connect two of the
three conductors together at one of the leads. Make this
connection as close to the RTD as possible (see Figure 5).
If only two conductors are connected between the RTD and
the URTDII, the device will not operate correctly.
3. Connect the cable shield and drain wires to the appropri-
ate terminal on the URTDII. At the opposite end, cut the
shield and drain wire short and tape them, to prevent short
circuits.
Do not connect this wiring at the RTD end.ote:N
4. If one or more of the 12 possible RTD inputs on the
module are not used, they can be left open or jumpered out
without affecting the operation of the protective devices.
3.3 Wire Routing
Wire routing is divided into two types: High voltage (440
Vac and higher) and low voltage (120 Vac and DC signals).
The control and the RTD wiring are low voltage lines.
Maintain at least 45 to 60 cm (1.5 to 2 feet) between high
voltage and low voltage conductors. Never route high volt-
age and low voltage lines in the same raceway.
Ifote:N a fiber optic link is used, run the optic cable in the
same cable tray as high voltage conductors.
3.4 Protective Device Connections
The URTDII can be connected to a protective device using
fiber optic cable. The fiber optic cable may be no longer
than 122 meters (400 feet) in length. This cable is available
from Hewlett-Packard using style number HFBR-ELS-xxx.
where xxx is the length of the cable in meters. This is plas-
tic fiber optic cable that has connectors already attached at
each end. Equivalent cable and connectors may be used.

4.0 COMMUNICATIONS
4.1 Fiber Optic Settings
A set of dip switches (S1) is located on the side of the
module. Dipswitch 10 is used to select the data output
format of the fiber optic port. Many products in the field
today are connected to the existing URTD module. This
module supports 11 RTDs providing only one Auxiliary RTD
to the user. To minimize the effort of replacing an exist-
ing module with a URTDII module, dipswitch 11 selects a
legacy mode that provides data in the same format as the
existing URTD module. Expanded mode adds the 2nd Aux
RTD, case temperature and hottest RTDs from each group
of RTDs. Table 5 shows the selection of this switch:
Table 5, Dips Switch Settings
Dipsw10 Mode
OFF 11 RTDs (Legacy Mode)
ON 12 RTDs, Case, Hottest (Expanded)
4.2 Modbus
4.2.1 General Modus Description
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. The fol-
lowing describes the configuration of the Modbus param-
eters.
4.2.2 Addressing
A set of dip switches (S1) is located on the side of the
module. These switches set the Modbus address/configu-
ration. Dipswitches 1 to 8 represent the binary address of
the URTDII. Dipswitch 1 is the most significant address bit
and dipswitch 8 in the least significant bit. Table 6 shows
an abbreviated example of the addressing. Valid addresses
range from 1 to 254. See notes below about reserved
addresses.
Address 00ote:N is a broadcast address and should not
be used in a typical Modbus system. If this address
is selected it will put the URTDII module in a mode
provided exclusively for IMR systems. Please refer to
IMR Documentation for further information.
Address 255ote:N is a reserved address. Normal Modbus
commands will not be interpreted correctly while the
unit is set to this address. In this mode the URTDII
should not be connected to a network because the
network protocol is not being handled. The URTDII
will respond to any message it received with a mini-
mum of a prompt character potentially disrupting any
other communications on the network.
