EDAM-4250
10 D
I
and 6 DO channels Digital I/O Module
The EDAM-4250 is a high-density I/O module built-in two port(RJ-45) 10/100 based-T interface for seamless
Ethernet connectivity. It provides
10 digital input and 6 digital output channels
with 3750VRMS Isolating
protection. All of the Digital Input channels support input latch function for important signal handling. Mean while,
these DI channels allow to be used as 300Hz counter. Opposite to the intelligent DI functions, the EDAM-4250
Digital Output channels also support pulse output function,
Auto-Off Time of digital output
and
DIO Synchronization
function.
