S320 Controller – basic unit

S320 is a freely programmable controller in a front panel housing with interfaces for RS232, RS485 and TCP/IP ethernet. Modern flash memories save programs, data and system routines.
A real-time clock and a battery-buffered data memory are onboard as well.


The membrane front plate includes three 6-digit LED displays and additionally three 4-digit text displays. Inputs can be made by five membrane keys. The basic unit is supplied with 24 Volt and it includes eight digital inputs and outputs with 24 Volt levels by default for easy communication with a PLC or for switching of magnetic valves, contactors or similar devices.
