Hardware core technology
Slot and dual bus architecture
16 universal slots; PCI high-speed bus+serial dual bus
✅ Supports IC695 (RX3i) CPU, power supply I/O、 Communication module (can be directly plugged into IC695ALG508-AA)
✅ Backward compatibility with IC694 and IC693 (90-30) old I/O modules, upgrading and reusing old modules for old projects
The backplane does not include a power supply, and the power supply needs to be separately configured with IC695PSA040/PSA140, supporting dual power supply redundancy.
Electrical parameters
Backplane bus power supply: 3.3V maximum 600mA; 5V maximum 240mA
On the left side of the rack, there is an isolated 24VDC input terminal; Integrated shielding grounding bar, unified module shielding grounding, improved EMC anti-interference
The serial expansion bus interface on the right side can be connected to an expansion rack to expand the I/O scale.
CA Three Anti Coating Unique Protection (Key) PCB Circuit Board Spray Industrial Conformal Three Anti Coating, Achieving Moisture, Mold, Salt Mist, Dust, and Slight Corrosion Resistance. Suitable for: offshore platforms, chemical, high humidity, dust, salt spray, corrosive gas cabinet environments.
Attention: The gold fingers of the connector and the positions of the connectors should be covered and not sprayed to ensure reliable contact during module insertion and removal.
Environmental and mechanical parameters (- CA and – AA basic specifications are the same)
Working temperature: -40 ℃~+85 ℃; Humidity 5-95% RH, no condensation
Vibration/impact meets the industrial standards of IEC60068-2-6/IEC60068-2-27
Only allow horizontal installation of DIN rails, prohibit vertical installation; IP20
Support RIPP hot swapping: RX3i series modules come with hot swapping, provided that the CPU firmware meets the module requirements.
Certified UL508, Class I Div2, ATEX Zone2 hazardous area certification.
System constraints
The maximum number of slots for a single rack is 16, slot 1 can accommodate CPUs, and the remaining slots are allocated for power supply I/O、 Communication module.
Can be mixed with AA backboards in the same system; But it is recommended to use all CA coated backboards and coated modules (such as IC695ALG508-CA) under harsh working conditions.
Market status: Original factories can still place orders, and there is a large circulation of spare parts
