ICC312 MTL Signal Isolator: Dual Output Repeater Power Supply

Overview of MTL ICC312 Performance

• Oiltech Controls presents the ICC312, a precision repeater power supply for mission-critical process loops.
• The ICC312 provides a stable, fully isolated DC supply to energize standard 2-wire transmitters efficiently.
• Engineers utilize this unit to split a single 4-20mA transmitter signal into two independent output channels.
• This device ensures high signal integrity by maintaining superior 3-port isolation between inputs, outputs, and power.

Frequently Asked Questions

• How does the LFD feature function during a signal loss?
• The transistor output turns OFF when the input current drops below 0.2mA, indicating a loop break.
• Can I use the ICC312 with an existing 4-20mA source?
• Yes, you can connect an external 4-20mA current source to terminals 8 and 9 directly.
• What should I check if my output signal is inaccurate?
• Verify your power supply voltage is between 20V and 35V DC and check for load resistance limits.
• Is this isolator suitable for high-vibration environments?
• Yes, the robust DIN-rail mounting and secure terminal design ensure excellent performance in industrial sites.
