4 20ma signal splitter singal isolator

OHR-M3 Series 4 20MA Signal Splitter

OHR-M3 Series 4 20ma signal splitter have a high- precision, wide-range and high-stability. With modular design, OHR-M3 Series are very convenient for collocating and updating. With technology (SMT), OHR-M3 Series are very compacted, cabinet and have a good linearity and high anti-jamming ability. OHR-M3 Series support RS-485 communication by protocol MODEBUS and RTU, long transmission distance (distance ≤ 1000 m, shielded wire advised). With compacted structure, OHR-M3 Series are convent for installation with standard DIN. OHR-M3 Series are powered with AC100V-265V or DC 24V (±10%) by switch power supply.
