The RTD Analog Input Module (IC670ALG620) accepts inputs from 4
independent 3-wireand/or 4-wire platinum, nickel, nickel/iron, or
copper RTDs.Module features include:
- Selectable resistance measurements in tenths of ohms, tenths of
degrees Fahrenheit, ortenths of degrees Celsius
- Individual channel configuration
- Selectable resistance ranges: 0 – 500 ohms and 0 – 3000 ohms
- Selectable RTD input as resistance or temperature (Celsius or
Fahrenheit)
- Reports high/low, underrange/overrange, open wire and input short
alarms.
- Uses optional discrete inputs and outputs for status and control.
- Two data acquisition rates based on 50 Hz and 60 Hz line
frequencies
- Configurable channel activation
Power Sources
No loop power is required for this module. The excitation current
for the RTDs is provided by the module, which automatically matches
the excitation current to each configured RTD type.
The RTD Input Module accepts four inputs from three-wire or
four-wire RTDs and converts the input level to a digital value.
Input spans support a variety of RTD types, as listed in the Module
Specifications section.
The analog
ital converter reads the voltage generated by each of the four
inputs. The A/D converter converts the differential measurement
into a binary value (15 bits plus sign), which is read by the
block’s microprocessor. The microprocessor sets the gain required
in the analog
ital converter for each individual input. The gain is based on the
RTD type that has been configured for that input.
The microprocessor selects the input by means of a solid state,
optically-coupled multiplexer.Three measurements are made for each
input: Excitation current, RTD resistance including field wire
drop, and field wire drop. From these three measurements, the
module calculates the RTD resistance. A DC/DC converter circuit
isolates the field side from the logic circuits.
The following illustration shows connections for 3-wire and 4-wire
RTDs.
No loop power is required for this module. The excitation current
for the RTDs is provided by the module, which automatically matches
the excitation current to each configured RTD type.
I/O Terminal Block Terminal Assignments
The Terminal Block with box terminals (IC670CHS002) has 25
terminals for each module. Each
accommodates one AWG #14 (avg 2.1mm2 cross section) to AWG #22 (avg
0.36mm2 cross section) wire, or two wires up to AWG #18 (avg.
0.86mm2 cross section). When an external jumper is used, wire
capacity is reduced from AWG #14 (2.10mm2) to AWG #16 (1.32mm2).
The I/O Terminal Block with barrier terminals (IC670CHS001) has 18
terminals per module. Each terminal can accommodate one or two
wires up to AWG #14 (avg 2.1mm2 cross section).
The I/O Terminal Block with Connectors (IC670CHS003) has one 20-pin
male connector per module.
