Proportional, Spring Return, 24 V, for 2 to 10 VDC or 4 to 20 mA Control Signal
The ZG-R01 500 Ω resistor converts the 4 to 20 mA control signal to
2 to 10 VDC.
WARNING Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it may be
necessary to work with live electrical components. Have a qualifi ed licensed electrician or other
individual who has been properly trained in handling live electrical components perform these
tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
