This unique plc allows up to 16 inputs to be evaluated and up to 8 relay isolated outputs to be controlled. The device may be connected directly to a 10baset or 100basetx ethernet lan. A built in website allows for web-managed configuration and status display of the controller, therefore no front panel is required. Optional a/d and d/a board allowing for 8 analog input and 8 analog output channels to be evaluated or be controlled. Easy to understand programming language. The controller is ideal in replacing older ttl type controllers such as those used to control half automatic screen printing equipment, security access curtains, punch presses, sheers and press breaks. It is also ideal for remote control of motors and fans for factory or environmental monitoring applications. The controller has a power supply and battery charger included, which can run the controller fully functioning for up to 8 days.
