ABB SM811K01 3BSE018173R1 Safety CPU Module

Input Type: Supports 8-channel analog input (e.g., voltage, current signals), compatible with standard industrial signals (e.g., 4-20mA, 0-10V).

Resolution: 16-bit high-precision ADC conversion, sampling accuracy ≤±0.05% FS (Full Scale), suitable for precise measurement requirements.

Anti-Interference Design: Built-in EMC filter circuit, supports isolated input (isolation voltage between channels ≥500V AC), applicable to strong electromagnetic interference environments.

Bus Protocol: Communicates with AC 800M controllers via backplane bus, supports protocol expansion such as Modbus RTU/TCP (requires matching with communication modules).

Electrical Interface: Adopts pluggable terminal blocks (e.g., Phoenix terminals), supports hot-swapping for convenient on-site maintenance.

Power Supply: 24VDC±20%, typical power consumption ≤10W, supports reverse polarity protection.

Environmental Adaptability: Operating temperature -20℃~+70℃, humidity 5%~95% (non-condensing), conforms to IP20 protection level, suitable for harsh industrial field environments.

Chemical/Pharmaceutical Industry: Real-time acquisition of analog signals such as temperature, pressure, and flow (e.g., data access from reactor sensors).

Power System: Signal processing of voltage/current transformers in substations, cooperating with PLC to implement relay protection logic.

Pressure/displacement signal acquisition for equipment such as injection molding machines and extruders, used for closed-loop control of process parameters.

Access to temperature and humidity sensors in central air conditioning systems to achieve building automation control.

Coordinates with ABB robot controllers (e.g., KUC series), controls gripper force or tool rotation speed through analog signals.

Rail mounting (35mm DIN rail), supports vertical or horizontal installation, requiring ≥50mm heat dissipation space reservation.

Status indicators: Power, Run, Error. Abnormalities are located by LED flashing frequency (e.g., corresponding indicator remains on in case of channel failure).

Software diagnosis: Module status codes (e.g., 1003 indicating channel overload) can be read via ABB Control Builder software, supporting remote log export.

Compatible with AC 800M controller firmware version V4.3 and above, requires use with ABB S800 I/O system.

For higher precision (e.g., ±0.01% FS), upgrade to SM812K01 (24-bit ADC).

For analog output functionality, use in conjunction with SM911K01 (8-channel analog output module).

In the presence of strong electromagnetic interference on-site, prioritize the full isolation design of SM811K01 to ensure data stability.
