WM SERIES Standard Signal Isolators/Power Distributors
DESCRIPTION:
WM T series DC standard signal isolators are designed to provide electrically insulated between input and output signal and prevent the transfer of interference voltages and currents. The signal isolator serves to electrically insulate a DC signal in the range of 4…20mA to 4…20mA;
Features:
Linear electro optic isolation
High precision transmitting
Low power consumption
Low temperature drifting
Provide DC 24V power supply (WBT3C1CU05/WBT3C4CU05)
APPLICATIONS:
The WM T series DC signal isolator can be used with measurement and control systems, such as DCS, PLC, etc.
WM standard signal isolators /power distributors have meet requirement of IEC 61010-1
