Frequently Asked Questions
- Q: What makes this module “intrinsically safe”?
A: It is designed to prevent sparking and limit thermal energy. This prevents ignition in flammable atmospheres. - Q: Can I use this module with standard sensors?
A: Yes, but you must use approved intrinsic safety barriers between the module and field devices. - Q: What PLC systems is this module compatible with?
A: It works with Modicon Quantum systems using Unity Pro, Concept, or ProWORX software. - Q: How does the broken wire detection work?
A: For 4-20 mA signals, the module detects when current drops below 4 mA and signals a fault. - Q: Can I use this module in non-hazardous areas?
A: Yes, but its special safety features make it more expensive than standard input modules.
