ICC212 Galvanic Isolated 4-20mA Signal Converter

Overview of the ICC212 Signal Converter

• The ICC212 serves as a dual-purpose current-to-current converter for industrial automation systems.
• Oiltech Controls engineers designed this unit to provide fully floating power for 2-wire or 3-wire smart transmitters.
• Users operate the ICC212 as either a dedicated repeater power supply or an isolated signal driver.
• This device ensures bidirectional HART digital signal transmission for seamless remote configuration of field instruments.

Frequently Asked Questions

• Q: Can the ICC212 support HART communication?
  A: Yes, the unit allows bidirectional digital signals superimposed on the 4-20mA loop.
• Q: How do I select between repeater or driver modes?
  A: The top-mounted power terminals allow you to configure the device for specific loop requirements easily.
• Q: Is the device protected against common mode noise?
  A: The 150dB common mode rejection ratio ensures stable operation in electrically noisy industrial environments.
• Q: What is the benefit of the 3-port isolation?
  A: It protects your control system by electrically separating the power supply, input, and output circuits.
• Q: Does this model fit standard DIN-rail systems?
  A: It installs onto both T-section and G-section rails, making it highly versatile for existing panels.
