Product Description

S***2 has total *6 channels isolated wet contact or dry contact or open-collector . Each channel also can work as **-bit counter , the maximum frequency is **0Hz for total *6 channels and ***0Hz for only one channel. Output bus is RS**5 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 RS**5 serial interface using the industry standard modbus protocol.
