METZ CONNECT Potential Isolator 230VAC 110502

For installations where a 230 VAC control signal must trigger a floating relay output without any direct electrical connection, the METZ CONNECT Potential Isolator 110502 provides a clean, safe interface. Unlike basic signal converters, this unit combines a compact DIN-rail housing with a 4 kV isolation barrier and a potential-free changeover contact, making it suitable for building automation, HVAC control, and industrial signal distribution.

Highlights

• Galvanic isolation between input and output up to 4 kV test voltage
• Potential-free changeover relay contact rated 250 VAC / 2 A
• LED status indication for operating voltage
• DIN rail mounting (TS35) for quick installation in distribution boards
• Wide operating temperature range from -25 °C to +70 °C
• Compact polyamide housing with IP20 protection

In daily use

The isolator accepts a 230 VAC input and drives an internal relay, providing a dry contact output that can switch low-power loads or feed into PLC inputs. Its screw terminals accept solid or stranded conductors, and the green LED confirms supply presence at a glance. The 1.5 VA power consumption keeps heat generation minimal, allowing continuous operation in confined enclosures.
