The IC695CHS012 is a PACSystem RX3i universal backplane. The backplane has 12 slots and

It supports high-speed peripheral component interconnect (PCI) and serial bus connections. The backplane is a necessary component because it provides an enclosure for the RX3i modules and connections.

It also carries the communication bus for internal communication between modules.

The IC695CHS012 consumes 600 mA at 3.3 VDC and 240 mA at 5 VDC.

It has physical dimensions of 18.01 x 5.57 x 5.80 (457.5 x 141.5 x 147.32) and supports horizontal mounting.

It can be mounted in an enclosure with an IP20 / NEMA/UL Class 1 protection rating. To achieve natural cooling and promote adequate air circulation, the

The backplate must provide 102 mm or 4 inches of clearance on all sides of the hardware. To meet the requirements of an ATEX Zone 2 hazardous area, the

The IC695CHS012 must be mounted in an IP54 or better enclosure with mechanical strength to withstand 3.5 Joules of impact energy.

The IC695CHS012 supports modules that are hot-swappable or removable and insertable under power.

This provides a distinct advantage, as it effectively reduces downtime

and allows maintenance activities such as module replacement and integrity verification to be performed without affecting the current operating modes of the attached controller and module.

The backplane also supports the installation of optional backplanes such as controller chassis and Ethernet expansion chassis.

The IC695CHS012 backplane has a TB1 terminal block that can be used to terminate an optional external 24VDC power supply for some IC693 and IC694 modules.

Single AWG 14-22 wire is recommended.

The IC695CHS012 backplane has an internal current rating of 240 mA at 5 VDC and 600 mA at 3.3 VDC.

The backplane must be placed horizontally and requires a minimum of 102 mm (4 inches) of space on all sides for proper operation and air cooling.

The IC695CHS012 general purpose backplane supports input terminals using single conductors from 14 to 22 AWG.

The terminals in slots 7 and 8 are typically used to isolate an external power supply. each slot in the IC695CHS012 backplane can be configured to receive a different component.

For example, a DC power supply can be connected www.abb-drive.com to one slot, while an AC power supply is used for both slots.
