Rockwell Automation 61C365 4 Output 4-20mA Analog Rail - Manual (Page 7)

1.0 INTRODUCTION
The products described in this instruction manual are manufactured
by Reliance Electric Industrial Company.
The 4 Output 4Ć20 mA Analog Rail module allows you to output four
4Ć20 mA analog signals from AutoMater,ĂAutoMaxr and DCS 5000
systems. Typically, the Analog Rail module is used with
potentiometers, valve actuators, pressure or flow transducers, and
meters in both drive control systems and process control systems.
The Analog Rail module is hardwareĆconfigurable by means of a
faceplate switch to emulate one of two types of devices, AutoMate
Rails or AutoMate Local Heads. In some hardware configurations,
the type of interface device available for the Analog Rail module will
determine the mode of operation that can be selected (see
figure 1.1).
The Analog Rail module operates in Local Head mode when it is
connected directly to one of the processor's four I/O ports in
AutoMate systems, to an AutoMate Local I/O Processor, or to one of
the four I/O ports of the DCS5000/AutoMax Remote I/O Head in
DCS5000/AutoMax systems. The Analog Rail data will take up four
registers in the host when operating in Local Head mode.
The module operates in Rail mode when it is connected to one I/O
port of a Local I/O Head, which in turn is connected to one I/O port
of an AutoMate processor. The Analog Rail module will occupy one
register of the host in Rail mode. The Rail mode is used to expand
the I/O address space available through the front I/O port of the
processor by multiplexing each group of four analog points through
one register. Note that the Analog Rail module cannot be used with
the Local I/O Head in DCS5000/AutoMax systems.
The Analog Rail module operates in Rail mode when it is connected
to one I/O port of the Power Module Interface (PMI) Processor
(B/M 60000), which is in turn connected to a Universal Drive
Controller (UDC) module (M/N 57552) which resides in an AutoMax
rack.
The remainder of this manual describes the functions and
specifications of the module. It also includes a detailed overview of
installation and troubleshooting procedures, as well as examples of
configuration and programming.
