PLC controller hardware PCB scheme. ATMega32L, RS485 industrial bus interface, 8 ADC inputs, 8 PWM out, 6 GPIO

- Discrete diode protection for high & low overvoltage for all input & interface contacs.

- Two types of RS485 input connectors (1RJ-45, 3RJ-11).

- Output RS485 RJ-11 connectors. The controller can act as connection hub on RS485 network with tree-like topology. Up to 3 output connections.
