Multi-channel recorders can control 4-20mA output currents for devices, power distributors, etc.
Essentials. A current signal of 4-20mA can be converted to a voltage signal of 1-5V and recorded for a long time. Measurements can be made without the use of a dedicated current input unit.
How to use: 1.Prepare a resistor of 250 (1 4W or more). (Please prepare the resistor by yourself.) High-precision metal resistors are recommended).
2.Connect the resistor of 250 to the terminal block of the data logger (+ - between terminals) as shown in the figure.
3.With the BT3562A, the maximum inter-terminal voltage of DC100V can be measured. (BT3563A can measure up to DC300V).
4.1-5vF. of the data logger can be useds.Range.
For loop testing of two-wire transmitters, use the DC source SS7012.
