Preliminary Instructions for Use
The T201DC100 can be mounted in any position and place, in compliance with the expected environmental conditions. Use the supplied accessory in the case of DIN rail mounting.
Note: Magnetostatic fields of considerable magnitude can alter the measurement. Please avoid installing the module near permanent magnets, electromagnets, or ferrous masses that induce strong alterations in the magnetic field. If the zero error is greater than the declared one, try a different arrangement or orientation.

Current Output for Loop 4 ÷ 20 mA
A diagram illustrates the current output connection for a 4-20 mA loop. It shows a power source (U) and a current meter (mA) connected in series with the device. The text states: "It is possible to connect directly on the 4 ÷ 20 mA loop in T201DC100 output a maximum voltage of 28 V."
Current Input
[attention] Please, install the module as shown in the figure. Pay attention to the direction of the current flow.
To measure the current passing through a cable, insert the cable into the central hole of the T201DC100. The maximum current that can be measured by T201DC100 is 100A.
To increase the current measurement sensitivity, insert the cable several times into the central hole of the T201DC100, creating a series of coils. The current measurement sensitivity is proportional to the number of turns. For example, if the full scale is set and the wire is wrapped around the hole 5 times, this creates 4 coils. The full scale will be 5 times lower, and the measurement will be more sensitive.
Arrange the coils symmetrically to preserve the precision of the instrument.
DIP-SWITCH SETTINGS
Use the dip-switches to choose the monopolar or bipolar scale and whether or not to activate the filter.
