6355-0054-01 is a part of Encitech, manufactured by Encitech Automation, Inc. It is a 9-in-1 Opto-Isolator Module featuring 8 optical isolator channels and one common input. It is designed to provide user-defined logic switching on any of the 8 input channels. This part is designed to accept a wide range of common analogue and digital inputs, including PNP, NPN, and DC signals. The device provides a logic level output when any of the input signals goes above a give level, as set by the user. The system also features built-in LED indicators to help the user set the proper parameters, as well as LED indicators to show when the module is in active operation. This part requires external power to drive the leds, and the devices can be connected together in a distributed configuration to save space and power. This makes it ideal for distributed automation applications.
