Signal Isolators / Converters / Splitters
Note :
The model SIG-221D operates on 20 to 32 VDC.
The models SIG-351D / 352D / 351T / 352T operates on both AC & DC Voltage; 20 to 265 V AC/DC.
The accuracy / p formance of the Module is not affected by the variations in the supply within sp cified limits. Use well- er
insulated copper conductor wire of the size not smaller than 0.5mm² for power supply connections ensuring proper polarity as
shown in Figure . . The 1 6
blow fuse rated for 0.5A current.
For safety and enhanced electrical noise immunity, it is highly recommended to connect Main Power Supply 'Earth'
to the terminal provided for earthing connection.
