The loop-powered isolator RH 1011 electrically isolates

0(4) ... 20mA standard signal circuits and transmits the measurement signal to the output with high accuracy. It thus avoids interference voltages being carried over and effectively suppresses interference. Due to the low internal voltage requirement of only 2.0 V, the high level of accuracy and the compact design, the RH 1011 is the first choice in plant construction.

The 12.5 mm narrow modular housing saves space in the control cabinet and facilitates installation thanks to the practical plug-in terminals.

The loop-powered isolator RH 1012 electrically isolates

0(4) ... 20mA standard signal circuits and transmits the measurement signal to the output with high accuracy. It thus avoids interference voltages being carried over and effectively suppresses interference. Due to the low internal voltage requirement of only 2.0 V, the high level of accuracy and the compact design, the RH 1012 is the first choice in plant construction.

Intelligent circuit technology and the consistent omission of highly integrated circuit components leads to an extremely long service life and reliability without falsification of the measurement signal.

The loop-powered isolator RH 1021 electrically isolates 0(4) ... 20mA standard signal circuits and transmits the measurement signal to the output with high accuracy. It thus avoids interference voltages being carried over and effectively suppresses interference. Due to the low internal voltage requirement of only 2.0 V, the high level of accuracy and the compact design, the RH 1000 is the first choice in plant construction.

Intelligent circuit technology and the consistent omission of highly integrated circuit components leads to an extremely long service life and reliability without falsification of the measurement signal.

The loop-powered isolator RH 1022 electrically isolates 0(4) ... 20mA standard signal circuits and transmits the measurement signal to the output with high accuracy. It thus avoids interference voltages being carried over and effectively suppresses interference. Due to the low internal voltage requirement of only 2.0 V, the high level of accuracy and the compact design, the RH 1000 is the first choice in plant construction.

Intelligent circuit technology and the consistent omission of highly integrated circuit components leads to an extremely long service life and reliability without falsification of the measurement signal.

The loop-powered isolator RH 11010 electrically isolates 0(4) ... 20 mA standard signal circuits and transfers the measurement signal to the output with high accuracy. It thus avoids interference voltages being carried over and effectively suppresses interference. Due to the low internal voltage requirement of only 2.5 V, the high level of accuracy and the compact design, the RH 11010 is the first choice in plant construction. The 6.3 mm narrow modular housing for 1 or 2 channels saves space in the control cabinet. The RH 11020 only requires a 3.0 mm DIN rail per channel. Intelligent circuit technology and the consistent omission of highly integrated circuit components leads to an extremely high MTBF, which means high long-term stability - without falsification of the measurement signal.

ISPB-20 sealing cover 1 module width

ISPB-25 sealing cover 2 module width

The ISR1-316/L contains 3 make contacts with advanced tungsten contacts. 

Switching on lighting fixtures can result in very high inrush currents.

A closing contact bounces 3-7 times until it closes completely. This creates an arc that can melt the contact surface. If the closed contact cools down, micro-welding can occur (contact sticks).

To avoid contact sticking, relays with a leading tungsten contact are used.

This allows switch-on peaks of 165 A / max. 20 ms for incandescent lamps, or 800 A / max. 200 µs for fluorescent lamps.  

The installation relay has a built-in protection diode and interference suppression capacitor. Supply voltage: 230VAC
