Measure or Source Current
4.1.2 DPI620G-IS Measure or Source Current (CH1)
Figure 4-2
shows CH1 set to measure or source a current with external loop power.
Figure 4-2: Measure Current on CH1 (Range ± 55mA)
1. Set the applicable channel options: CH1, Measure (or Source), Current, mA.
2. Complete the electrical connections as shown and continue with the measure or source
operation.
3. Source only (Automation): set the applicable output value.
4.1.3 DPI620G-IS Source Current, Internal 15V Loop Power, CH2
Figure 4-
3
shows CH2 set up to source current (0 to 24mA) with an internal loop power (15V).
An internal resistor (10 ohms) and series current source MOSFET are between the ‘mA+/V’ and
‘m
A-/COM’ terminals. The current limit of the Loop power is 40mA.

1. Set the applicable channel options: CH2, Source, Current (15V), mA.
2. Complete the electrical connections as shown and continue with the source operation.
3. Source only (Automation): set the applicable output value.
