S3306 has total 16 channels isolated 0 through 36 volts DC input, Each input channel also can work as 32-bit counter input, the maximum frequency is 100Hz for total 16 channels and 1000Hz for only one channel. Output BUS is RS485 with has surge protection, to reduce interference by serial port communication, the output isolated by high speed opto-couplers. The modules are slave devices that can be easily controlled via the RS485 serial interface using the industry standard Modbus protocol.
