M-7041-A5 - 14-channel High Voltage Input Isolated Digital Input (counter) Module with DCON and Modbus Protocol
by ICP DAS
|
|
|
|
14-channel High Voltage Input Isolated Digital Input (counter) Module with
DCON and Modbus Protocol, supports operating temperatures from -25 ~ +75°C
|
|
|
The M-7041-A5 provides 14 channels for high voltage digital input, each of
which features photocouple isolation. The input voltage level could be as high
as 150V. In addition, either sink- or source-type digital input can be selected
via wire connections, and all channels are able to be used as 16- bit counters.
4 kV ESD protection and 3750 VDC intra-module isolation are standard. The
M-7041-A5 support both the Modbus RTU and DCON protocols, which can be confi
gured via software.
