The signals are connected together via resistors by an internal
common ground.
The Type 9482 Temperature Input Module is designed to receive up to
8 input signals from 2-/3- or 4-wire RTDs and potentiometers or up to
eight thermocouples and mV sensors. Via the channels 6 and 7 a
connection of an external cold junction compensation (CJC) via an
RTD is also possible. The module transmit those signals to the IS1
CPU & Power Module.
The module is nonincendive for installation in a Class I, II, III, Division
2, Group A-G or Class I, Zone 2, Group IIC/IIB hazardous location
according to NEC Article 504/505 or Canadian Electrical Code, CSA
C22; Providing intrinsically safe connections for Class I, Division 1,
Groups A-G or Class I, Zone 0, Group IIC/IIB hazardous locations
listed below.
Entity parameters for wiring configuration are on the next pages.
Notes:
1. Intrinsically safe apparatus may be mV sources, thermocouples,
CJCs, RTDs, potentiometers or an Approved System or Entity
device connected in accordance with the manufacturer´s
installation instructions.
2. For Entity concept use the appropriate parameters from
above to ensure the following:
 V
V or V
OC t max
 I
I or I
SC t max
3. The values of La and Ca in the tables on the next sheets are the
maximum values for combined inductance and capacitance
(including cable inductance and capacitance). The values for La
and Ca marked in grey are the values determined according to
curves and tables of IEC 60079-11, Annex A. These grey marked
values may be used for assessment as per IEC 60079-14,
intrinsically safe circuits with only one source of power.
4. Suitable separation must be maintained between wiring of each
I.S. input channel.
5. For Installation in Division 2 or Zone 2 see Certification drawing
for IS1 resp. IS1+ Remote I/O System No. 9400 6 031 004 1 or
9400 6 031 006 1 as part of the documentation of the CPU &
Power Modules.
