MCR 3-way Isolating Amplifier

The configurable MCR-FL-C-UI-UI-DCI-24/230 3-way standard signal isolation amplifier can process
0 to 20 mA, 4 to 20 mA and 0 to 10 V standard signals on the input side.

The 3-way isolation between signal input, output and supply is set up as "safe isolation" with a test voltage of 4 kV ?. Depending on the application, the signal transmission cut-off frequency can be set as either 10 kHz (approximately) or as a< 10 Hz filter. On the output side, any of the three standard signals are available.

Adjustment after configuration is not necessary, as each transmission variant is calibrated and stored in
the device. The transmission error is always < 0.1%.

The 3-way standard signal isolation amplifier has a long-range supply of 20…253 V AC/DC and is available in 12.5 mm (0.492 in.) narrow housing with pluggable screw connection.
