The SEM1022 dual channel current loop booster provides extra drive capability to two separate 4-20mA current loops simultaneously from a single compact DIN-rail mounted unit, requiring only 2.7V from each existing loop to operate.
The SEM1022 dual channel current loop booster provides extra drive capability to two separate 4-20mA current loops simultaneously from a single compact DIN-rail mounted unit, requiring only 2.7V from each existing loop to operate. It is the practical fix when additional instrumentation, longer cable runs, or extra load has reduced available loop voltage on more than one circuit, restoring reliable signal drive without re-engineering the loops.
Each channel benefits from full galvanic isolation and the same high accuracy and low power operation as the rest of the Status SEM1000 series, letting one SEM1022 do the work of two single-channel boosters in half the panel space. It is widely specified across process control, water treatment, and industrial automation applications wherever loop voltage budget is tight on multiple circuits.
