Basic information
Series: Micro820.
Type: Digital I/O module (speculated).
Number of I/O points: Possibly 16 I/O points (specific input and output allocation unknown).
Electrical characteristics
Power supply: Usually 24V DC.
Input characteristics: Input voltage may be in the range of 19.2 - 30V DC, logic 1 signal ≥15V DC (minimum 2.5mA), logic 0 signal ≤5V DC (maximum 1mA), input impedance, response time, etc. may be similar to other modules in the same series, such as input impedance 3.4kΩ, response time ≤4ms.
Output characteristics: If it is a relay output type (speculated from the R in the model), it has the general characteristics of relay output, such as being able to withstand a certain current load, being able to switch AC or DC loads, and having certain indicators for contact life. The possible maximum output current is around 2A - 5A per point (different for different specific models), and can withstand a certain surge current.
Communication and expansion
Communication port: There are 1 RS-232 port (supporting Modbus RTU) and 1 USB port (for programming/debugging).
Expansion capability: Supports up to 5 Micro800 series plug-in modules (such as analog, communication modules).
Physical characteristics
Dimensions: Refer to the same series of products, which may be around 90mm (height) × 23.6mm (width) × 70mm (depth).
Weight: About 100g - 150g.
Mounting method: DIN rail or panel mounting.
Terminal type: Removable screw terminal.
Environmental parameters
Operating temperature: -10°C to + 55°C (horizontal installation).
Storage temperature: -25°C to + 70°C.
Humidity: 5 - 95% RH (non-condensing).
Protection level: IP20 (panel mounting).
Certification and Compliance
Certification: Usually UL, CE, cUL, RoHS, etc.
