EDAM-4254
5 differential DI and 8 DO channels Digital I/O Module
The EDAM-4260 is a high-density I/O module built-in two port(RJ-45) 10/100 based-T interface for seamless
Ethernet connectivity. It is a high-density I/O module. It provides 5 differential digital input and 8 digital output
channels with 3750VRMS Isolating protection. The EDAM-4254 Digital Input channels support 5 isolated differential
digital input (sink/source) channels and All of the Digital Input channels support input latch function for important
signal handling. Meanwhile, these DI channels allow to be used as 300Hz counter. Opposite to the intelligent DI
functions, the EDAM-4254 Digital Output channels also support pulse output function, Auto-Off Time of digital
output and DIO Synchronization function.
