WT1600 - 5A and 50A Input Elements

The Yokogawa WT1600 offers two separate input modules, 5A max and 50A max. It can be configured with any mix of 5A and 50A modules up to a maximum of 6 input elements. Each element consists of a voltage and current input (watt meter).


There are two major differences to be considered when configuring a WT1600. The most appealing spec is the maximum direct input current of 50A, however the following must be considered:

• The bandwidth of the two modules is different. The 5A module offers 1MHz bandwidth, while the 50A offers 100kHz max.


• The minimum current range is also different. The 5A offers a low 10mA range, while the lowest range on the 50A module is 1A.
