About 1746-NO4V
The AB 1746-NO4V is a Four (4) point, non-isolated SLC 500 standard
analog voltage output module. It has an output range of -10 to
10 Volts -1 LSB DC with backplane current ratings of 55 mA at 5
Volts and 145 mA at 24 Volts. AN external 24 VDC power supply may
use with
this module by activating SW1 external. If the backplane power is
sufficient, the backplane power may be used as the power source of
this
module instead of an external supply. The 1746-NO4V has a field
wiring to backplane isolation of 500 Volts DC, and a maximum load
reactance
of 1 µF and maximum load current of 10 mA.
This module is a factory calibrated module and uses a 16-bit two’s
complement binary communication format. The 1746-NO4V is enclosed
in
an open-type enclosure and mounts on a 1746 chassis. It is also
equipped with an LED status indicator and a removable terminal
block (RTB).
Recommended wire size for this module is #14 AWG maximum wire size.
Its update time is 512 µs for all the channels that are in
parallel, and
it has a step response time of 2.5 ms at 95%. The 1746-NO4V’s
operating temperature ranges from 32 to 140 degrees Fahrenheit, its
non-operating temperature ranges from -40 to 185 degrees Fahrenheit
and its non-condensing relative humidity for operation and storage
is 5
to 95%. The 1746-NO4V’s has a maximum overall accuracy drift of +/-
54 ppm/degrees Celsius full scale.
The AB 1746-NO4V module is a Programmable Logic Controller (PLC)
analog output module that belongs to the SLC 500 product
platform. The output channels of this module produce voltage signal
ranging from -10 to +10VDC signals.
When installing this module to the chassis, certain guides may be
used for determining the ideal slot or chassis assignment of the
module.
Two (2) general factors are considered such as ambient Temperature
and Electrical noise. For electrical noise, the module is
recommended to
be installed away from AC or high levels of DC voltage.
Additionally, it is best to install this module away from the
system power supply. For
ambient temperature consideration, the chassis that is nearest to
the enclosure bottom is the recommended installation chassis.
This module does not support removal under power. Never remove this
module when power is applied as electrical arcs may happen causing
damage to the electronic circuitry. The module may also be
installed with the Removable Terminal Block (RTB) installed in its
front panel. Use
14 AWG wire and limit a maximum of Two (2) wires terminated in the
same terminal. This is to provide room for troubleshooting as well
as be
able to close the module cover.
Analog outputs may be assigned to a PID controller output, a result
of Mathematical operation or a manual value entered from a Human
Machine
Interface (HMI), or Supervisory Control and Data Acquisition
(SCADA). These are control commands sources. It may also be used to
re-transmit signals for reference of other devices to implement
their monitoring, recording and conversion applications. For stand
alone
controllers that require control coordination such as load sharing
function, analog outputs may be used to send the reference signal
of all
involved controllers and devices.
