Isolated Current Loop Splitter SEM1200 MKII

Dual Isolated Outputs — Splits one passive 4-20mA input into two independent, galvanically isolated 4-20mA outputs.
500 VDC Galvanic Isolation — Isolation between ports protects connected instrumentation from ground loop currents.
Independent Zero/Span per Channel — Front-panel potentiometers allow each output to be trimmed separately.
High Accuracy — Typical output uncertainty of ±0.05% of full range.
No Commissioning Adjustment — Requires only an initial operational check — no re-calibration needed out of the box.
Compact DIN Rail Enclosure — Space-efficient footprint for dense control panel builds.

It takes a single passive 4-20mA input signal and splits it into two separate, isolated 4-20mA outputs that can each feed a different device.

Yes. Both output loops must be powered externally; the splitter itself provides isolation, not loop power to both outputs.

The SEM1200 MKII provides 500 VDC galvanic isolation (flash tested to 1 kV) between each port.

Yes, each output has its own front-panel accessible zero and span adjustment.
