UCAM-550A is a fast data logger that repeatedly measures a maximum of 1000 channels at an interval of 0.02 s.
Because it is capable of high-speed synchronous measurement, this unit measures a wide range of phenomena, from static to dynamic phenomena.



· Synchronous sampling of all channels
· Synchronously sample at 50 Hz for 1000 channels
· 5 types of measuring units available


Models UCAM-550A: With DCS-100A
UCAM-550A-0: Without DCS-100A
Channels Maximum of 50 channels/unit
(Possible up to 5 units of the measuring unit)
(Each measuring unit measures 10 channels.)Measurement is possible of up to 1000 channels at maximum by adding an optional software DCS-106A.
*The public command corresponds up to 20 units (Max. 1000 channels).
*DCS-100A corresponds up to 6 units (Max. 300 channels).
Sampling Method Synchronous sampling of all channels
Sampling Frequencies 1, 2, 10, 20, and 50 Hz

Response frequency depends on the measuring unit.
USM-51B/52B*, USS-51B, USV-51B, UST-51B: DC to 7.8 Hz
Deviation:0.5 to -3.5 dB
*For temperature measurement with USM-51B/52B using scanning mode, the updating rate is approx. 1 s.
