When the device is in current measurement mode, the input impedance is 10Ω. Therefore voltage input should not be connected to the device while
in current mode. Otherwise the device will deteriorate. If it is necessary to switch from the voltage measurement mode to the current measurement
mode while the device is running, It must be removed and then changed to one of the input type current measurement modes.
OUTPUT
15VDC , Max. 50mA
Sensor Supply
Life expectancy for relay 30.000.000 Switching for no-load operation; 300.000 switching for 10A resistive load at 250VAC.
