EDAM-4255
8 DI
and 8 DO channels Digital I/O Module
The EDAM-4255 is a high-density I/O module built-in two port(RJ-45) 10/100 based-T interface for seamless
Ethernet connectivity. It provides
8 digital input channels, and 8 digital output
channels
.
All of the digital input
channels support the input latch function for important signal handling. The digital output channels support source
type output. Opposite to the intelligent DI functions, the EDAM-4255 Digital Output channels also support pulse
output function,
Auto-Off Time of digital output
and
DIO Synchronization
function.
