Product Details
The AB 1756-IF16 is a non-isolated analog current/voltage I/O
module. In order to connect to a ControlLogix chassis, it requires
an RTB, or a removable terminal block housing, of either the
1756-TBS6H or 1756-TBCH. This input module has 16 points available.
These points allow users to wire the module in different ways,
unlike other modules. The 1756-IF16 can be wired using three
different methods, depending on the user's and application's
requirements: single-ended wiring, differential wiring, and
high-speed mode differential wiring. The single-ended wiring method
is best when all input devices are tied to a common ground. This is
for comparing one side of the signal input to signal ground to get
the difference, which is then used by the module in generating
digital data for the controller. 16 single-ended wirings can be
done. When applications do not have a common ground or can have
separate signal pairs, using the differential wiring method is
recommended. This wiring method is also for environments where an
improved noise immunity is needed. The channels in a differential
mode are not completely isolated from each other.
One channel may affect the reading of another channel if multiple
differential input signals have different voltage common
references. When this happens, users should wire the input on
different modules or replace the non-isolated module with an
isolated input module. 8 connections are allowed in this mode.
Lastly, the high-speed mode differential wiring method allows for
the fastest possible data updates. However, certain conditions are
required for users to be able to use the high-speed mode. First, it
uses the differential wiring method. Second, when in this mode only
one of every four channels on the module can be used. The power
consumption of the 1756-IF16 module is 2.3 Watts and it has a total
backplane power of 2.33 Watts. The input range is ± 10 Volts, from
0 to 10 Volts, 0 to 5 Volts, or 0 to 20 mA. The current draw of
this module at 5.1 Volts is 150 mA, or is 65 mA at 24 Volts. The
voltage and current ratings of the backplane are 5.1 Volts DC, 150
mA at maximum, and 24 Volts DC 65 mA at maximum. The input current
range is from 4 to 20 mA and the input voltage range is from -10 to
10 Volts and limited to 100VA. The Voltage power dissipation is
around 2.3 Watts and the current power dissipation is 3.9 Watts.
The thermal dissipation for the voltage is 7.84 BTU/hour and 13.3
BTU/hour for current. It also has a maximum overvoltage protection
of 30 Volts DC (voltage) and 8 Volts DC (current).
