AB 1746-NR8 RTD INPUT MODULE 8 CHANNEL SLC-500 OPEN STYLE 55 MA
About 1746-IM16 :
This module is exclusively used for SLC 500 systems. It may be specifically used with the Two (2) variants of SLC 500 such as Fixed and modular hardware style. It occupies single slot of any chassis used and does not require an external power supply instead, this module is powered by the backplane power generated by the system power supply.
This module is primarily used for Temperature applications as RTD sensors are specifically used to measure temperature readings. The resistance capability of this module is applicable for measuring displacement or movement or mechanical devices. Typically, it is used for measuring the length of travel, movement reflected by the decrease and increase in the resistance reading.
This module supports 2-Wire, 3-Wire, and 4-Wire RTD sensors. For a 2-wire RTD, recommended wires are Belden 9501 shielded cable or equivalent. For a 3-Wire or 4-Wire RTD, use Belden 9533 or Belden 83503 cable. For a 2-Wire RTD, avoid long cable runs as it reduces accuracy of measurement. It cannot be avoided, the effect or long wires may be minimized by using a lower gauge cable such as an AWG #16 wire instead of AWG #24. Basically, use a cable with lower resistance per foot. The terminals of the Removable Terminal Block (RTB) are intended for single wire connection only.
Channel status can be monitored via the LED indicator while the module operation can be monitored through the LED status indicator. This module has a low-pass digital filter and a programmable input filters. The module’s analog to digital conversion is sigma-delta modulation. Its auto-calibration process occurs every time the module is powered up that is also programmable to a specific cycle of every 5 minutes. The RTD types present on the 1746-NR8 module are copper, platinum, nickel-iron, and nickel. The terminal block that is compatible with this module is an AB 1746-RT-35 terminal block.
The backplane power consumption of the 1746-NR8 module is a maximum of 1.82 W, and the power consumption is 0.5 W at 5 Volts DC and 1.32 W at 24 Volts DC. The 1746-NR8’s backplane current consumptions are 100 mA at 5 Volts DC and 55 mA at 24 Volts DC. Its maximum common mode voltage is +/- 1 Volt, while its maximum permanent overloads are +/- 5 mA for the current and +/- 5 Volts DC. The isolation voltage of the 1746-NR8 module is continuous at 5 Volts DC between the channels and 500 Volts AC for 1 minute between the inputs and the backplane,
