GE IC693ACC312 Analog output module

GE IC693ACC312 Analog output module

Basic information
Series: GE Series 90-30.
Product type: Analog output module, mainly used to convert the digital signal inside the PLC into analog signal to control the external analog actuator.
Technical parameter
Number of output channels: There are usually 4 analog output channels, which can control 4 analog devices at the same time.
Output signal type: Support a variety of analog output signals, common DC voltage signals (such as 0-10V, ±10V, etc.) and DC current signals (such as 4-20mA, 0-20mA, etc.).
Resolution: Generally 12 or 16 bits, it can accurately convert digital quantities to analog quantities to meet the control tasks with different accuracy requirements.
Accuracy: The output accuracy is high, usually within the range of ±0.1% – ±0.5% FS (full scale), to ensure the accuracy of the control signal.
Isolation mode: photoelectric isolation or transformer isolation is used between channels and between the output and the PLC internal circuit to effectively prevent external interference signals from entering the PLC system, while protecting the module and external equipment from the impact of electrical failure.
Power requirements: External DC power supply is required, and the general working voltage is about 24Vdc ± 10% to ensure the normal operation of the module.

Functional characteristics
Signal conversion and output: The digital signal sent by the PLC can be accurately converted into the corresponding analog signal, and output to the external equipment, to achieve the accurate control of analog actuators such as regulating valves and frequency inverters.
Diagnosis and protection function: with self-diagnosis function, can monitor the working status of the module in real time, if the fault is detected, it will send an alarm signal to the PLC or the upper computer through the LED indicator light or the communication interface. At the same time, the module also has overload protection, short circuit protection and other functions, which can effectively protect the module and external equipment from damage under abnormal conditions.
Configuration flexibility: The output signal type, range, update rate and other parameters of the module can be flexibly configured by means of software configuration or hardware jumper to adapt to different application scenarios and control requirements.
Communication interface: Through the connection with GE series 90-30 PLC backplane bus, high-speed and reliable data communication with PLC, ensure that the module can receive the control instructions sent by PLC in time, and feedback the status information of the module to the PLC, to achieve the overall coordinated operation of the system.
