ABB UAC317AE HIEE300725R0001 is an 8-channel analog input interface module compatible with the ABB 800xA DCS system. Primarily deployed for acquisition, isolation and signal conversion of continuous analog signals such as temperature, pressure, flow and liquid level from industrial field sites, the module converts standard 4–20 mA and 0–10 V signals transmitted by field sensors into digital signals recognizable by the control system. It enables high-speed data communication via the backplane bus and serves as a core base signal acquisition board installed inside DCS cabinets for process industries, supporting the construction of continuous production control loops across multiple industries.

Product Features
Electrical Specifications
Input power supply: 24 VDC; maximum overall power consumption: 5 W. Each channel accepts two standard analog input types: 0–10 VDC voltage signal and 0–20 mA current signal. Signal response time ≤ 1 ms, meeting the requirements of real-time closed-loop control.
Physical Structure
Dimensions: 170 mm × 100 mm × 90 mm; total weight: 0.5 kg. Ingress Protection rating: IP20, for installation only in standard indoor control cabinets. The board is fitted with status LEDs to indicate three operating conditions: normal power supply, channel fault and communication error.
Communication & Isolation
High-speed data transmission via backplane bus; compatible with multiple industrial protocols including Modbus, Profibus DP and RS485. Each of the 8 channels features independent optoelectronic isolation, with single-channel withstand voltage complying with industrial insulation standards.
Environmental Performance
Stable operating temperature range: -40 ℃ to +70 ℃. Resistant to normal dust and minor vibration; not suitable for unprotected environments with high humidity or heavy corrosive substances.
Functional Configuration
8 independent configurable analog input channels. Each channel’s parameter can be individually switched between current and voltage acquisition modes via upper computer software. Open-circuit diagnosis is supported: fault codes will be actively uploaded to the control system once sensor wiring disconnection occurs.
Product Advantages
- Stable channel acquisition accuracy with 12-bit signed resolution. Measurement errors are kept extremely low under weak signal conditions, suitable for precision process parameter monitoring.
- Full-channel electrical isolation on a single module eliminates signal drift caused by on-site electromagnetic interference and ground potential difference, reducing accidental interlock faults of the system.
- Hot-swap recognition for rack backplane; automatic address assignment after module insertion, greatly cutting working hours for on-site cabinet commissioning and capacity expansion.
- Wide operating temperature range enables stable long-term continuous operation in high/low temperature workshops and outdoor power distribution cabinets, featuring strong environmental adaptability.
- Multi-protocol compatible communication interface allows direct connection to controllers and remote upper monitoring computers without extra adapter accessories, lowering system hardware configuration costs.
- Standard clip-on mounting design; disassembly and installation do not require removing the overall cabinet wiring, facilitating later fault replacement and maintenance.
- Built-in multi-stage hardware protection circuits automatically cut off channels upon overvoltage, overcurrent and reverse wiring, preventing main circuit burnout of the board due to sensor failures.

Product Comparison
UAC317AE vs UAC318AE
Channel Configuration: UAC317AE features 8 analog input channels; UAC318AE comes with 16 analog input channels. UAC318AE is the preferred choice for high-density signal acquisition applications. Isolation Scheme: Both models adopt independent per-channel isolation with equivalent anti-interference performance. Power Consumption: Total power draw of UAC317AE is 5W, while UAC318AE consumes 8W. Power load calculation is required for cabinets equipped with multiple multi-channel modules. Applicable Scenarios: UAC317AE is suitable for small and medium-sized facilities and single-loop control systems; UAC318AE is recommended for multi-point measurement cabinets in large chemical plants and power stations.
UAC317AE vs UAC310AE
Functional Positioning: UAC317AE only supports analog signal acquisition; UAC310AE integrates both analog input and analog output functions and can directly drive regulating valves. Channel Count: UAC317AE has 8 input channels; UAC310AE is configured with 4 input channels plus 4 output channels. UAC310AE shall be selected when signal output control loops are required. Cost Difference: UAC317AE has lower hardware cost and delivers better cost performance for projects that only require signal acquisition without output loops.
