SCHNEIDER 140SAI94000S Modicon Analog Safety Input Module

Hardware Specifications
Channel configuration
8-channel differential secure analog input (software cannot be split into 16 single ended, standard 8-channel secure acquisition)
Support signal types
Current: 4-20mA/0-25mA (mainstream industrial transmitters)
Voltage: 0-10V
Collection performance
Resolution: 16 bits
Measurement accuracy: ± 0.3% FS (full scale)
Module global refresh cycle: 15ms
Low pass filtering: 15Hz/-3dB, suppresses on-site power frequency interference
Isolation and Electrical
channel ↔ Backplane bus isolation: 1500Vrms
Input impedance: 287 Ω (current mode)
Wire breakage diagnosis: Automatic detection of wire breakage and short circuit faults in 4-20mA circuits
Backplane data
Occupy 13 input words in PLC memory, upload measurement values+channel diagnostic status codes
environmental parameters
Working temperature: -25 ℃~+60 ℃
Protection: IP20 (only installed inside the cabinet)
Power Supply: Rack Backpanel 24VDC, Module Power Consumption Approximately 100mA
function
Dual channel voting diagnosis
Internal dual ADC independently collects values from the same channel and automatically compares and verifies them; Directly reporting channel failure and triggering safety failure if deviation exceeds the standard
Full channel self diagnosis
Real time monitoring: sensor disconnection, circuit short circuit, over range, ADC hardware failure, module power supply abnormality
Fault safety failure mechanism
When the module itself fails, it reports the safety fault status to the PLC and cooperates with the safety program to achieve SIS interlocking shutdown, avoiding dangerous working conditions
Hardware isolation to prevent crosstalk
Each channel is independently isolated, and multiple transmitter failures will not interfere with each other for safe signal acquisition
application
Petroleum and Chemical SIS Safety Instrumented System (Level, Pressure, Temperature Safety Interlocking)
ETS/safety protection circuit for thermal power and gas turbine units
Emergency shutdown system for long-distance oil and gas pipelines
Safety monitoring of high-pressure equipment in metallurgy and chemical industry
