The Omron CS1W-PTS56 is a dedicated Process Analog I/O Unit within the CS-series platform, engineered for precise resistance thermometer input acquisition. With 8 independent channels supporting Pt100 and JPt100 sensors, this unit delivers industrial-grade accuracy (±0.3% of PV) and rapid 250 ms conversion across all inputs. Designed for seamless mounting on CS-series CPU or Expansion Racks, the CS1W-PTS56 stores process data in hexadecimal or BCD format within the CIO Area, while the DM Area allows flexible configuration of sensor type, input range, and process value alarms. Its 3-wire connection minimizes conductor resistance influence (0.4°C/Ω max), ensuring stable readings even in long cable runs. Ideal for temperature-critical processes, this unit is 100% original and new, ready for prompt delivery.
