ABB 07AI91 GJR5251600R0202 AC31 Analog I/O module

420mA, 010V, RTD(PT100), thermocouple (J/K TYPE etc) input signal type

Resolution: 16 bits or higher

It is based on PROFINET, EtherNet/IP, Modbus TCP.

Supply voltage: 24V DC

Operating temperature range: -20°C ~ +60°C

ABB 07AI91 adopts 8-channel analog input, and can be configured flexibly as 4-20mA current signal / 0-10M voltage signal, used for sensor data acquisition such as temperature, pressure, flow, etc.

Please note, as this is an old relevant information and either it not acceptable or too risky for the industry.

ABB 07AI91 has a small metal shell, and supports DIN rail installation and can be easily launched and maintained.

All channels are electrically isolated with the system bus, and have anti-interference ability of ±2kV surge protection, appropriate for strong electromagnetic interference environment (motor control, high-frequency equipment, etc.)

ABB 07AI91 supports Modbus RTU protocol natively, and can communicate directly with PLC, SCADA system or host computer, and realize real-time data transmission.

Expansion of PROFIBUS network and third-party devices (Siemens, Schneider, etc.) through PROFIBUS-DP gateway (ABB 3BSE020514R2 or similar)

Delivers DIL switch address configuration and can accordingly interface device addresses within 1-255 to satisfy complex networking needs.

ABB 07AI91 also has built-in channel-level fault detection, real-time monitoring of signal over-limit, disconnection, short circuit and other abnormal conditions, and LED indications or communication protocols are reported.

You will be able to input redundant power supply (24V DC±10%) for each port with a 0.25 V±10% power supply and a dynamic range of fluctuations, to ensure it remains in a stable state.

Production process monitoring:real-time data collection: able to obtain reactor temperature and pressure sensor data, control valve opening, and pump speed, PID closed-loop control.

Safety supervision: Link combustible gas detector, conduct leakage risk supervision in real time, and trigger emergency shutdown or alarm

2.Power and energy management

Monitor oil temperature in transformer, bus voltage, current transformer signals, and more.

Introduction 1.1 In photovoltaic power stations, inverter is considered the major source of energy generation, and inverter output voltage and current data are regularly collected to enhance the optimization of MPPT  [1-9].

Water treatment: monitor the pH value, dissolved oxygen, turbidity and other parameters, control the dosing system and aeration equipment, and make the effluent reach the standard.

Water PCMS: Urban Water Supply Allotment Monitor: Collect data of storage water level and pipeline pressure; Optimize pump start-stop strategy for energy saving

Data from clean room environmental monitoring: temperature and humidity, pressure difference and dust particle counter for compliance with GMP certification.

Fermentation Process Control: Real-time collection of dissolved oxygen and pH signal of fermenter, real-time adjustment of stirring speed and feeding amount to improve yield.
