SS8188 - 8ch DI 8ch PNP Output Modbus TCP-IP Server Module

Description

SS8188 is a Modbus TCP server unit with 8 digital input channels and 8 PNP outputs. Up to 4 counters at 32 bit, measuring up to 300 Hz frequency are available.

The Ethernet interface allows real time read and write of the internal registers. The built-in Web Server of SS8188 allows the remote visualization and acquisition of the digital inputs state, to access and configure the main Ethernet parameters via web browser.

The SS8188 realizes a full electrical isolation against the effects of all ground loops. LED signalling for Ethernet activity, input and output, and power supply allow direct monitoring of the system functionality. Connection is by removable screw-terminals (inputs, outputs and power supply) and RJ45 plug (Ethernet).
