IsoTrans 41

For isolation of 0(4) … 20 mA standard signals, up to 3 channels

The Knick IsoTrans 41 with transformer-based isolation offer properties which no other loop-powered DC isolator can even come close to.
Suitable for galvanic isolation of 0/4 to 20 mA signals. Thanks to the 0.2 % fault class and an internal voltage requirement of just 1.2 V, this isolator can be used for a broad range of applications. The A2 modular housing with a width of 22.5 mm for max. 3 isolators offers optimum space usage in multichannel mode.
The full encapsulation guarantees maximum reliability even in extreme conditions.

The Task
If no power supply is available, the galvanic isolation of 0(4) … 20 mA standard-current signals requires investing in power supplies.

The Problems
Many products only provide
loop-powered isolation with an insufficient degree of accuracy. But the need for high measurement accuracy requires an isolator design which meets the highest demands.
The load capability of the 20 mA source is limited and therefore requires efficient use of the load voltage.

The Solution
The Knick IsoTrans 41 with transformer-based isolation offer properties which no other loop-powered DC isolator can even come close to. Thanks to the 0.2 % fault class and an internal voltage requirement of just 1.2 V, this isolator can be used for a broad range of applications.
