ET-7242 - 16 Digital Outputs
by ICP DAS
|
|
|
|
Modbus TCP Based Ethernet I/O Module with 2 Ethernet ports for daisy-chain networking, with 16 Digital Outputs and can be configured as Sink type. Communicable over Modbus TCP and Modbus UDP protocol, Supports operating temperatures of -25°C ~ +75°C (-13°F ~ 167°F) and has a din rail mount.

The ET-7242 provides 16 sink-type digital output channels. It features optical isolation for 3750 VDC of transient overvoltage protection and doesn’t have channel-to-channel isolation. The power-on value and safe value of digital output channel are programmable. In some industrial applications, the user can connect the output channel of ET-7242 to the RM series relay module to switch inductive loads.
