ESP-0806-B PLC
A highly economical PLC for small applications; a powerful alternative to smart relays with advanced features and C#-based programming.
Powerful Programming Language
C#-based (ST)
Its Structured Text (ST) programming language is based on C#, making it easy to write highly complex programs. It is much simpler than LADDER or FBD and offers the power of the C language alongside the flexibility of a PLC.
Rich and Evolving Libraries
Features robust libraries for various calculations along with dedicated PLC commands. This software library is continuously being developed and updated.
Real-time Firmware
With the execution of real-time firmware, commands are processed instantly.
Designed for Small Applications
Economical Alternative to Smart Relays
For projects that can be controlled with 8 inputs and 6 outputs, engineers usually turn to smart relays like Siemens LOGO. The ESP-0806-B1, with its economical price and far superior software capabilities, is the best alternative for these projects.
Adjust Values Without a Display
This device features two BCD Switches that allow you to define two numbers from 0 to 15 (separately or as a two-digit number) directly on the device, without needing an HMI or display.
Need More I/Os?
Model B does not support expansion cards. If your project requires more inputs/outputs, you can use the D and E series, which support up to 8 expansion cards.
Define Two Numbers from the Device
Set two numbers (0-15) directly
In many small projects, defining two numbers from 0-15 as timer or counter settings, either as two individual numbers or one two-digit number, can eliminate the need for a display screen.
Easy Access to S1, S2 Values
The values set on the S1 and S2 binary switches can be easily read by calling them directly in your program.
Programming Example
