The RTD input module is sensitive to electrostatic discharge.

ATTENTION: Electrostatic discharge can damage

integrated circuits or semiconductors if you touch

backplane connector pins. Follow these guidelines

when you handle the module:

• Touch a grounded object to discharge static potential

• Wear an approved wrist-strap grounding device

• Do not touch the backplane connector or

connector pins

• Do not touch circuit components inside the module

• If available, use a static-safe work station

• When not in use, keep the module in its

static-shield bag

This product has the CE mark and is approved for installation within

the European Union and EEA regions. It has been designed and

tested to meet the following directives.

RTD Input Module Calculate Power Requirements 3 The module receives its power through the 1771 I/O power supply. The maximum current drawn by the RTD module is 950mA (4.75 Watts). Add this current to the requirements of all other modules in the I/O chassis to prevent overloading the chassis backplane and/or backplane power supply. Determine Module Placement in the I/O Chassis You can place your module in any I/O module slot of the I/O chassis except for the extreme left slot.

RTD Input Module ! ATTENTION: Remove power from the 1771 I/O chassis backplane before you install the module. Failure to remove power from the backplane could cause: • module damage • degradation of performance • injury or equipment damage due to possible unexpected operation & -# ') .& $( -# + ".$ , )( -# -)* ( )--)' )! -# # ,,$, -# - ".$ -# ') .& $(-) *),$-$)( Important: **&1 !$+' / ( *+ ,,.+ )( -# ') .

RTD Input Module Connect Wiring to the Field Wiring Arm 5 Connect your I/O devices to the field wiring arm (cat. no. 1771-WF) shipped with the module. ! ATTENTION: Remove power from the 1771 I/O chassis backplane and field wiring arm before removing or installing an I/O module. • Failure to remove power from the backplane or wiring arm could cause module damage, degradation of performance, or injury.

RTD Input Module RTD INPUT 9 The front panel of the RTD input module contains a green RUN indicator and a red FAULT indicator. At power-up, the module momentarily turns on both indicators as a lamp test, then checks for: • correct RAM operation • EPROM operation • EEPROM operation • a valid write block transfer with configuration data If there is no fault, the red indicator turns off.
