(connector and module)
● Acquisition of the momentary, maximum, minimum and
average value, plus transferring data of each measuring point scan to the
ALMEMO® device.
● DC voltage
or DC current signal are scanned with 1kHz.
● Pure digital
data transmission to the measuring instrument.
● Connector
sockets electrically isolated and overvoltageprotected.
☞ The measuring module is not
designed for operation
with selector switch board ES5590MF.
