Klemsan PISO passive signal isolators

PISO is a range of passive signal isolators from Klemsan. Designed as a low-cost alternative to active signal isolators, they electrically isolate extra low voltage analog signals. They can also assist in mitigating ground loops, ungrounded signals, induced voltage spikes and electrical noise in long cable runs to protect expensive industrial PLCs and I/O equipment.

The PISO range includes analog current inputs for both single and dual channels in one compact DIN rail housing plus a splitter type with a single input to dual output. For example, one analog sensor’s output can be fed into two devices such as a local LED display and PLC I/O for control in the same compact housing.

Designed to isolate and retransmit, the PISO range will convert the analog output type to 0–20 mA, 4–20 mA, 0–5 V or 0–10 V. Incorporating overcurrent protection and very low output ripple, the PISO range are designed to guarantee the analog output accuracy value less than 0.1% error in respect with the analog input measurement.
