GE FANUC IC697MDL340 , 24 Volt AC, 32-Point Input module , Series
90-70
Product Description
The IC697MDL253 is a 24 Volt AC, 32-Point Input module of the GE
Fanuc Series 90-70. This module provides 4 isolated groups of 8
points each. This allows each group of 8 points to be used on a
different phase of the AC supply. It comes with a 20ms filter and
is compatible with a proximity switch. The input module is
resistive and delivers 24 volts AC to the 32 points in the four
isolated groups, each with eight points. Characteristics of the
input are compatible with a diverse range of proximity switches. At
the top of the input module, you will find LED indicators that will
display the ON/OFF status of each point on the PLC.
To ensure accurate placement with a similar input module in the
field, the module is mechanically keyed. The module does not
require jumpers or DIP switches for user configuration.
Configuration relies on MS-DOS or Microsoft Windows 95 or Windows
NT operating systems and rides on TCP/IP protocol or via the SNP
port. The programming software is normally installed on a
programming device such as a Personal Computer, AT, IBM or PS/2.
IC697MDL253 module is compatible with a myriad of input devices
such as electronic proximity switches (both 2 and 3-wire), selector
switches, limit switches as well as selector switches. Input
current is normally 10mA when ON with a 2-mA leakage current when
OFF. There is a preference for 3-wire proximity switches due to
their provision of low voltage drop when ON and low current leakage
in the OFF state.
This input module is designed to be compatible with 2-wire devices
such as two-wire proximity switches which get their power from
signal connections. It’s important to note that each type must be
examined for compatibility in both ON and OFF states. Each module
comes with a mechanical key ring to provide a fool proof
functionality that prevents unintentional substitution of one
module model for another in a slot. During field wiring, a wire
from the source of power to the input power terminal for each group
is required. The detachable field terminal board accepts wires
sizes ranging from #22 (0.36mm2) to #14(2.10mm2). If they are of
the same size, 2 wires can be terminated on one lug.
Wiring procedures:
Firstly, switch off power before removal or installation or
installation of terminal boards. You can access the jackscrew that
secures the terminal in place by opening the hinged door on the
module. The terminal board is then removed by turning the jackscrew
counter clockwise until it’s full disengaged. Once this step is
complete, swinging it out.
The terminal board accommodates wire ranges from AWG #22 right
through AWG#14. A maximum insulation diameter of .135 inches should
not be exceeded when using AWG#14. For a perfect connection, two
wires can be terminated on any terminal, provided they are of the
same size. The terminal board is crafted to accommodate a maximum
of 40 AWG #14 (2.10mm2) wires. Wire markers should be placed
approximately 8 inches from the terminal end if AWG #14 are to be
used. The space provides ample room for closing of the hinged door.
After all connections are completed, secure the wire bundle tightly
using cable ties. A door label insert comes with every module to
indicate circuit wiring information of the module. There’s a slot
provision for insertion of the label on the hinged door. The
outside label is color coded for quick identification of voltage
type. Blue indicates low voltage while Red indicates high voltage.
For ideal ventilation, leave a 6-inch clearance above and below the
rack grill.
