GE IC698CHS017B Racks, 17-slot, Front and Rear Mount

GE IC698CHS017B Racks, 17-slot, Front and Rear Mount

INTRODUCTION

The RX7i rack can be used for all RX7i CPU and I/O configurations, Series 90™-70 I/O, and VME modules. Backplane connectors are spaced on 0.8" (20.3mm) centers to accommodate single-width RX7i modules, VME modules, and single-width Series 90-70 modules. Double-width Series 90-70 modules use two slots each. The rack accepts a power supply in slot 0 and a CPU in slot 1. The RX7i CPUs with Ethernet daughter card are double-width modules and use slots 1and 2. The remaining slots can be used for one of the following I/O combinations: 

fifteen single-width modules (with no doublewidth modules installed), 

eight double-width modules, or a combination of double-width and single-width modules.

FEATURES

Provides slot sensing for rack-type I/O modules. No jumpers or DIP switches on the I/O modules are required for addressing of these modules. 

Provides automatic daisy chaining of interrupt acknowledge and bus grant signals so no blank slot jumpers are required. 

Provides J2 backplane connectors to allow highspeed VME transfers of up to 64 data bits per cycle.
Accepts plug-in RX7i AC power supplies 

Supports higher wattage power supply for high

current configurations. 

Supports an optional cooling fan assembly (required for IC698CPE020 or IC698CRE020).

Slot Addressing

I/O point references for modules in an RX7i rack are configured using the CIMPLICITY® Machine Edition Logic Developer-PLC software. For information on configuration, see the software online help and the CIMPLICITY Machine Edition Logic Developer-PLC Getting Started manual, GFK-1918.

Main Features

Number of slots:

Provides 17 slots to meet the configuration needs of various I/O modules and VME modules.

Installation Mode:

Supports front and rear mounting for easy layout and wiring in the control cabinet.

Backplane connectors:

The backplane connectors are spaced 0.8 inches (20.3 mm) apart to accommodate single-wide RX7i modules, VME modules, and single-wide 90-70 series modules.

Double-wide 90-70 series modules use two slots each.

Module Configuration:

Rack slot 0 accommodates a power supply and slot 1 accommodates a CPU.

RX7i CPUs with Ethernet daughter cards are double-wide modules and use slots 1 and 2.

The remaining slots can be used for one of the following I/O combinations: 15 single-wide modules (no double-wide modules installed), or a combination of double-wide and single-wide modules.

Environmental Adaptability:

The RX7i rack is considered an open unit and therefore must be installed in an enclosure with a protection rating of IP54 or better.

Total rack dimensions are 11.15 inches H x 19 inches W x 7.5 inches D (283 x 483 x 190 mm).

Cooling and Ventilation:

If a fan assembly is installed, it is recommended that the RX7i racks allow at least 23 cm (9 inches) of clearance between them to allow for removal and replacement of individual fans.

Sufficient space must be left around the racks to allow for the air circulation required for module cooling.

Grounding and Connections:

The power supply, CPU, and all RX7i modules have metal faceplates with the top and bottom of the faceplate screwed directly to the enclosure to ensure that the faceplate is grounded to the rack.

Some Series 90-70 I/O modules have a grounding clip that contacts the conductive bottom rail when the module is fully inserted.

Software Configuration:

I/O point references for modules in the RX7i rack are configured via CIMPLICITY® Machine Edition Logic Developer-PLC software.

Application Areas

The GE IC698CHS017B Rack is widely used in various industrial automation fields, such as manufacturing, process control, energy management, and so on. It can be used as an important part of the PLC system, providing a stable mounting platform for the CPU modules, I/O modules and other plug-in modules in the system to ensure the stable operation of the whole system.

Precautions

Installation and Maintenance:

During installation and maintenance, follow the guidelines and instructions in the product manual to ensure proper installation and removal of the module.

Regularly check the working status of the rack and modules to ensure their normal operation.

Troubleshooting:

If you find any faults or abnormalities in the rack or module, please use the diagnostic tool to troubleshoot them in time and take appropriate repair or replacement measures.
