ABB SDCS-PIN-4B Digital Input Module

Product Short Description

Signal Type: Analog input (AI)/Analog output (AO)/Resistance Temperature Detector (RTD).
Number of Channels: 16 channels (each channel is independently isolated).
Isolation Voltage: 1500V AC between channels; 2500V AC between the field side and the system side.
Rated Load: For current signals, ≤ 350Ω (4 – 20mA); for voltage signals, ≥ 100kΩ.
Wiring Capacity: The maximum wire cross – section is 2.5mm² (spring – type terminals), supporting single – core or multi – core wires.
Operating Temperature: – 40°C to + 85°C (no condensation).
Protection Level: IP20 (needs to be installed in the control cabinet).

High – density Signal Transfer: Provides 16 independent signal channels, reliably connecting field sensor/actuator cables to the control system cabinet.
Electrical Isolation Protection: Each channel has a built – in signal isolation barrier to eliminate ground loop interference and protect the control system from electrical surges on the field side.
Convenient Maintenance Design: Adopts plug – gable terminals, allowing for module replacement or channel maintenance without powering off.
Wide Signal Compatibility: Supports 4 – 20mA current signals, 0 – 10V voltage signals, and direct connection of resistance temperature detectors (RTDs).
Visual Diagnosis: Each channel has an independent LED status light, real – time indicating the signal on – off and power – supply status.
Anti – interference Design: Built – in electromagnetic shielding layer, in line with the industrial environment EMC immunity standard (IEC 61000).
Tool – free Wiring: Spring – clip terminals support a maximum wire diameter of 2.5mm², enabling quick installation without crimping.

Industrial Automation and Control Systems: Commonly used in factory automation and production line control to monitor and control various production processes.
Machine Control: In mechanical and equipment control, it can be used to monitor and control the machine status, sensor inputs, and actuator operations.
Process Control: In industries such as chemical, petroleum, and natural gas, it is used to monitor and control industrial processes to ensure production stability and quality.
Building Automation: In building and facility management, it can be used to monitor and control lighting, HVAC, and safety systems.
Power Distribution and Control: In the power industry, it is used to monitor the grid status, circuit breaker status, and the operation of power equipment.
