Function and system design

Electronic acquisition, display, recording, analysis, remote transmission and archiving of analog and digital
input signals.
Multichannel data recording system with multicolored TFT display (170 mm/7" screen size), galvanically
isolated universal inputs (U, I, TC, RTD, pulse, frequency), digital input, transmitter power supply, limit relay,
communication interfaces (USB, Ethernet, RS232/485), internal SD memory, external SD card and USB stick.
100 ms scan rate for all channels. ReadWin
data evaluation.
Note!
The number of inputs, outputs and relays contained in the basic device can be individually extended using a
maximum of five plug-in cards. The Memograph M provides power directly to connected two-wire
transmitters. The device is configured and operated via 4 keys and the navigator (jog/shuttle dial) by means of
®
the interface and ReadWin 2000 PC software or an external keyboard. The online help makes onsite
operation easier. Measured values, events and alarms are coded in accordance with the serial protocol and then
transmitted.
