Description

1771-IR | Allen Bradley Discrete Input Module

Description: The Allen-Bradley 1771-IR is a PLC5 Resistance Temperature Detector (RTD) input module. This module features Six (6) input channels compatible for Copper and Platinum RTD type. It is specifically used for Temperature measurements supporting Celsius and Fahrenheit units of measurement. It has a scan time of 50 ms for 6 channels.

Technical Specifications for 1771-IR

The Allen-Bradley 1771-IR is a PLC-5 RTD input that features a natural binary BDC-supported actual temperature and Ohm readings data format. This device does not require any kind of external power. It consists of 6 three-wire RTD Inputs. The channel update resolution for this device brings in a combination of 50ms/6 channel and 16 bits +sign (1.0 Celsius /1.0Fahrenheit/bit). The voltage range for the 1771-IR input module is 100 Ohms platinum and 10 Ohms other. It has a backplane current range of 800mA. The DC signal delay in On-state is 10ms and in the Off-state it is 50ms while the AC signal delay in On-state is 45(+/- 15) ms. These input modules have a life of up to 100 million operations because it meets the requirement for a voltage of 10-276V AC. The 1771-IR supports Celsius and Fahrenheit units of measurement. It can be used in temperature measurement range of -200 to +870 Degree Celsius for Platinum sensor and -200 to +260 Degree Celsius for Copper sensor. It has a resistance range of 1.00 to 600.00 Ohms and resolution of 0.1 Degree Celsius or 0.1 Degree Fahrenheit when used with Platinum sensor and 0.3 Degree Celsius or 0.5 Degree Fahrenheit. The 1771-IR draws Current from the backplane amounting to 950 mA at 5VDC with Power Dissipation of 4.75 Watts and Thermal Dissipation of 16.2 BTU/hr.
