7B14

GENERAL DESCRIPTION

Hz filter preconditions the RTD signal prior to amplification,

The 7B14 is a low cost, single-channel signal conditioning

module that interfaces, amplifies and filters input voltages from

a wide variety of two-and three-wire platinum, copper and

nickel Resistor Temperature Detectors (RTDs) and provides a

precision output of either +1 V to +5 V or 0 V to +10 V, linear

with temperature. Model 7B14 features a nonlinearity of +0.05%

maximum (Pt and Cu RTDs). RTD excitation current, three-

wire lead resistance compensation and a predictable upscale

open circuit indication provide a complete signal conditioning

solution. Rated to operate with a nominal +24 VDC supply,

Model 7B14 is mix-and-match and hot-swappable with other

7B Series input modules, so it can be inserted or removed from

any socket in the same backplane without disturbing system

power.

provided by a low drift input amplifier. The output section

contains a two-pole low pass filter (-3 dB @ 3 Hz) and a buffer

amplifier. The two-pole output filter and subsequent buffer

ensure that a low noise, low impedance (<1Ω) signal is available

at the output to drive loads to 2 kΩ minimum.

The three input pins of Model 7B14 are fully protected up to

+30 VDC. A 250 uA excitation current for platinum and nickel

RTDs and a 1mA excitation current for copper RTDs is

provided to create an input voltage to the 7B14. This current

also provides the upscale open circuit indication. A one-pole 3
