• Accuracy: 0.2%
• 3-way galvanic isolation
• Screw-fit terminals removable
• DIN rail mounting
• Power supply: 19...40 V DC, 19...28 V AC

Isolating amplifier for DC voltages up to 3600 V

Isolating Amplifier for High-Voltage to 3.6 kV DC

The SINEAX TV829 is an isolating amplifier for voltages of up to 3.6 kV DC. It is intended for the measurement of operating voltage and operating current for DC railway systems, but is also suitable for monitoring electrical drives and battery powered (emergency power) systems. It complies with EN 61010 and EN50124.

Isolating amplifier for electrical isolation of DC signals. Processing of unipolar, bipolar and live-zero signals, load boosting and signal conversion option.

• Electrical isolation between input, output and auxiliary power
• Flexible: more than 250 different input and output combinations, can be configured with jumpers
• Supply power monitoring with green LED
• P12 housing for top-hat rail mounting

Isolating amplifier, 2 channels

Isolating amplifier for electrical isolation of DC signals. Processing of unipolar, bipolar and live-zero signals, load boosting and signal conversion option.

Isolating amplifier, 1 channel, output Ex or non Ex,

Isolating amplifier for electrical isolation of DC signals. FSK compatible TV 808-115/116 variants with intrinsically safe output are especially well suited for controlling intelligent I-P converters in explosive atmospheres. The HART bypass allows for transmission of bidirectional FSK signals based on the HART protocol.
