ICPDAS ET-7244
Ethernet I/O Module with 2-port Ethernet Switch and 8 channel Digital In and 8 Digital Out
● Built-in Web Server
● Web HMI
● Support for both Modbus TCP and Modbus UDP Protocols
● Communication Security
● Dual Watchdog
● Wide Operating Temperature Range: -25 ~ +75°C
● I/O Pair Connection
● 8 channel Digital Out
● 8 channel Digital In
The ET-7244 provides 8 wet contact digital input channels and 8 sink-type digital output channels. It features optical isolation for 3750 Vrms of transient overvoltage protection but doesn’t provide channel-to-channel isolation. Each input channel can be used as a 32-bit counter and each output channel can drive 300 mA load.
The power-on value and safe value of digital output channel are programmable. It can safely be used in applications where hazardous voltages are present.
