3103
Isolated repeater
3103
– Isolation and 1:1 conversion of standard current signals
– Slimline housing of 6 mm
– Response time < 7 ms
– Low cost
– Simple - no setup needed
Application
• Isolation and 1:1 conversion of standard current signals.
• Galvanic separation of analog current signals.
• Elimination of ground loops and measurement of floating
signals.
• A competitive choice in terms of both price and technology for
galvanic isolation of current signals to SCADA systems or
PLC equipment.
• Installation in ATEX Ex zone 2 / IECEx Zone 2 / FM division
2.
• Suitable for environments with high vibration stress, e.g.
ships.
Connections
Technical characteristics
• The input is protected against overvoltage and polarity error.
• Factory-calibrated measurement ranges.
• Inputs and outputs are floating and galvanically separated.
