ABB AI815 3BSE052604R1｜Analog Input Module｜

Specification
Channel configuration
8-channel single ended unipolar analog input, the entire board is a set of ground isolation; The same module can only be configured with unified current or voltage, and cannot be mixed
Support standard signals
Current: 4-20mA, 0-20mA (universal for two-wire transmitters)
Voltage: 0-5V, 1-5V DC
Collection performance
AD resolution: 12 bits
Complete machine accuracy: maximum error ± 0.1% FS
Temperature drift: ≤ 50 ppm/℃
Full channel refresh cycle: 10ms
Power frequency suppression: 50/60Hz suppression>40dB, resistant to on-site frequency conversion interference
Input impedance: voltage ≥ 10M Ω; current circuit with built-in 250 Ω sampling resistor
Maximum cable length: 600 meters
HART Core Capability
Built in HART direct circuit, supporting HART 5 smart transmitter; The module comes with a 24V current limiting transmitter for each channel, which can directly drive two-wire pressure/flow/liquid level instruments. It supports online reading of instrument parameters, ranges, and diagnostic information using a handheld device

Mechanism
Isolation method: 8-channel overall group ground isolation, no isolation between channels
Insulation withstand voltage: On site side ↔ Backplane bus 500V AC
Single channel hardware current limiting and short-circuit protection, single channel failure will not damage the entire card
Support automatic detection of 4-20mA circuit disconnection, fault upload controller alarm
