Input Parameters

Digital input: the module is usually equipped with 16 digital input channels, which can receive TTL/CMOS level signals. Input response time is very short, typical value is less than 1ms, which can quickly capture the state changes of external devices. Support a variety of input modes, such as active high, active low, rising edge trigger, falling edge trigger, etc., can be set flexibly through the module configuration software. Input signal isolation voltage up to 500V AC, effectively preventing the impact of external electrical interference on the module.

Analog Input: Generally has 8 analog input channels, supports voltage (e.g. 0 - 10V, ±10V) and current (e.g. 4 - 20mA) two types of input signals. The resolution of the analog inputs is up to 12-bit, which enables high-precision signal acquisition. The input signal range can be configured by software, and it has over-voltage protection function, when the input voltage exceeds 120% of the rated range, it will automatically carry out current limiting protection to ensure the safety of the module.

Output Parameters

Digital outputs: 16 digital output channels, the output type is transistor output, the maximum output current can be up to 2A, which can directly drive small relays, solenoid valves and other loads. The output response time is also less than 1ms, which can realize fast equipment control. The output signal isolation voltage is 500V AC, which can effectively isolate the external devices and modules and improve the stability of the system.

Analog Output: Usually 4 analog output channels are provided, which can output voltage (e.g. 0 - 10V, ±10V) or current (e.g. 4 - 20mA) signals. The resolution of analog output is 12 bits, with high output accuracy and full scale error less than ±0.5%. The output signal has a short-circuit protection function, when the load is short-circuited, it will automatically cut off the output current to protect the module and external equipment.
