Frequently Asked Questions

• What is the maximum number of I/O points this rack supports? It depends on the specific HC900 modules installed; consult the HC900 hardware guide for configurations.
• Can I mix different module types in one rack? Yes, the rack supports any combination of compatible HC900 CPU, analog, and digital I/O modules.
• What is the power requirement for the backplane? The integrated power bus typically requires a 24V DC supply; check module specifications for total load.
• Is this rack suitable for harsh environments? The steel construction provides good durability, but for extreme conditions, ensure the selected I/O modules have appropriate ratings.
• Does it include the terminal blocks for wiring? Terminal blocks are usually included with the I/O modules, not with the rack itself.
