Product Details
The AB 1756-IRT8I module is a high-resolution analog I/O module. In
particular, it is an Eight (8) point isolated temperature sensing
module compatible with RTD, Thermocouple and millivolt signals. The
module is part of the ControlLogix system and requires the 36-pin
RTB or Removable Terminal Block (RTB). Compatible RTB are 1756-TBCH
or the 1756-TBS6H. It has 2 CJC sensors for thermocouple use. The
CJC sensor accuracy is +/- 0.3 degrees Celsius, The channel
sampling rate of the module is only determined by the RPI value
because the 1756-IRT8I does not offer the RTS parameter. Also,
channels configured for thermocouple inputs perform a lead
resistance self-calibration when the module power is cycled.
Features of the 1756-IRT8I module include multiple module input
ranges, a notch filter, under-range/over-range detection, a digital
filter, process alarms, a rate alarm, a sensor offset, a 10-ohm
copper offset, wire-off detection, temperature units, sensor types,
thermocouple wire length compensation, synchronized sampling, and
cold junction compensation.
The 1756-IRT8I has multiple input ranges available, namely 1 to 500
Ohms, 2 to 1000 Ohms, 4 to 2000 Ohms, 8 to 4000 Ohms, and -100 to
100 millivolts. It supports 24-bit resolution with ranges of 0 to
510 Ohms with 0.06 milliohms per count, 0 to 1020 Ohms with 0.12
milliohms per count, 0 to 2040 Ohms with 0.25 milliohms per count,
0 to 4080 Ohms with 0.50 milliohms per count, and -101 to 101
millivolts with 0.01 microvolts per count. RTD sensors that are
supported include 100, 200, 500, 1000 Ohm platinum, alpha=385, 100,
200, 500, 1000 Ohms platinum, alpha=3916, 120 Ohms nickel, alpha
672, 100, 120, 200, 500 Ohm nickel, alpha=618, and 10 Ohm copper,
alpha=427. The RTD excitation current of the module is 600
microamps. The thermocouple types for this module are B, C, D, E,
J, K, N, R, S, T, and TXK/XK (L). Its thermocouple linearization is
ITS-90. The module has open circuit detection times of 2 seconds
for a thermocouple input and 3-wire RTD input and of 5 seconds for
a 4-wire RTD input. It should be noted that there is no open
circuit detection when wires are simultaneously disconnected from
the INx/RTD C and INx/RTD D terminals on the same channel (with x
representing the channel number). Noise rejections are available
for the module. At normal mode, it is 75 dB at 60 Hertz. During
common mode, it is 125 dB at 60 Hertz 1000 Ohms differential, 120
dB at 50 Hertz 1000 Ohms differential, and 160 dB at 600 Volts 100
Ohms differential.
