ALLEN BRADLEY 2.5A 5VDC 1785-LT B PROGRAMMABLE PROCESSOR CONTROLLER MODULE NEW
The AB 1785-LT2 module has 512 I/O. The maximum user memory words of this module are 13K expandable to 17K or 21K. The 1785-LT2 is intended for operation in the pollution level industry environment 2, in category II applications (as defined in the publication of IEC 60664-1). This module can operate at an altitude of up to 2000 meters without derating. If you connect or disconnect the cable and the terminal block or if you insert or discharge the module when the power is on, an electrical arc may occur. This may cause an explosion if the 1785-LT2 is installed in a hazardous location. Make sure the power is switched off and that the area is not hazardous before disconnecting the module.
The 1785-LT2’s operating temperature is 0-60 °C (32-140 °F). The
storage temperature is -40-85 °C (-40-185 °F). The relative
humidity of this module is from 5-95% without condensation. The AB
1785-LT2 has an operating shock of 30 g (3 pulses, 11 ms). The
nonoperating shock is 50 g (3 pulses, 11 ms). Separate this module
from other equipment and crop walls to allow convection cooling.
Convection cooling pulls the air in a vertical column to the top of
the processor, cooling it down. This cooling air shall not exceed
60 ° C (140 ° F) at any point immediately below the processor. If
the air temperature exceeds 60 ° C, install the fan carrying
filtered air or recirculate the internal air inside the enclosure,
or install the air/heat exchanger unit

The AB PLC-5 processors have ports configurable for either a Data
Highway Plus messaging communication link or a Universal Remote I/O
link. As a Universal Remote I/O port, it can be configured as
either an I/O scanner port or an I/O adapter port. As an I/O
scanner port, it monitors and controls the I/O on the link by
communicating with the I/O adapters for those I/O. As an adapter
port, it communicates only with the I/O scanner port on the link,
passing a maximum of one I/O rack of input and output data between
the two to provide distributed processing.
The scanner-mode PLC-5 controller can:- gather data from node
adapter devices in remote I/O racks - process I/O data from 8-,
16-, or 32-point I/O modules- address I/O in 2-, 1-, or 1/2-slot
I/O groups- support a complementary I/O configuration - support
block-transfer in any I/O chassis - ladder logic program using a
language that is representative of relay logic.- performing
diagnostics- programming discrete control
Use the 1785 for subroutines for storing recurring sections of
program logic that can be accessed from multiple program files. A
subroutine saves memory because you program repetitive logic only
once. The JSR instruction directs the controller to go to a
separate subroutine file within the logic controller, scan that
subroutine file once, and return to the point of departure.
Main Control Programs (MCPs)
Separate sequential logic from ladder logic and structured text as
a way of modularized your process and making troubleshooting
easier. Use several main control programs (MCPs) to define one main
control program for each particular machine or function of your
process. MCPs accommodate independent or non-sequential activities
