The DT81’s universal analog input channels can automatically select measurement range based on the signal level. These channels are isolated and over voltage protected to provide reliable monitoring in noisy environments.
Supported measurement and sensor types include temperature, DC voltage, current, 4-20mA loops, resistance, bridges, strain gauges and frequency - all returned in engineering units of your choice. Switchable excitation and triggering are provided on all channels to simplify wiring and installation.
The DT81’s universal digital channels provide input, output and counter inputs to 100KHz. Some channels can also be used as phase encoder inputs. In addition, two dedicated counter channels have adjustable thresholds for the monitoring of low level signals such as magnetic pick-ups. Other digital features include trigger input for event logging and a latching relay output to control or power external devices.
Superior Data Storage and Communications
With up to 5 million data points stored in a secure, non-volatile internal memory the DT81 gives peace of mind data logging. Versatile, user defined memory allocation provides flexible data storage solutions. A further option allows channel data to either overwrite or stop logging once the memory is full.
The DT81’s superior communications devices provide RS232, Ethernet, USB and USB memory stick ports together with modem dial-in and dial-out functions. TCP/IP is supported enabling communications over a local or wide area network.
