The IMASI23 Analog Input Module is a Harmony rack I/Omodule that is part of the Symphony Enterprise Managementand Control System. It has 16 analog input channels thatinterface isolated thermocouple, millivolt, RTD, and high levelanalog signals to a controller with an analog-to-digital conversion resolution of 24 bits. Each channel has its own analog-to-digital converter and can be independently configured tohandle the desired input type. These analog inputs are used bya controller to monitor and control a process. The IMASI23 module can be used as a direct replacement forthe IMASI03 or IMASI13 modules with only minor modifications. Changes to specification S11 in function code 216 arerequired to handle the differences in resolution choices. Verification of power supply sizing calculations and system currentrequirements could be necessary because of the change inpower consumption.
Characteristics of thyristors
(1) bidirectional conductivity
Thyristors have bidirectional conductivity, that is, they can conduct current at both forward and reverse voltages. This allows thyristors to be used in AC and DC circuits to achieve bidirectional current control.
(2) Switching characteristics
The thyristor has the switching characteristic, that is, under the action of the control voltage, it switches from the off state to the on state. Once the thyristor is switched on, it remains switched on until the current drops to zero or is disconnected by an external control. This switching characteristic enables the thyristor to realize efficient current switching control in the circuit.
(3) Trigger control
The on-state of the thyristor can be controlled by triggering the current. When enough current is applied by the Gate, the thyristor switches from the off state to the on state. This trigger control allows the thyristor to precisely control the on-off of the current in the circuit.
(4) High current and voltage tolerance
Thyristors can withstand considerable current and voltage. This makes it suitable for high power circuits and power control systems, such as motor control, power converter and other fields.
(5) Fast switching speed
The thyristor has a fast switching speed and can be switched from the off state to the on state in a nanosecond. This makes it suitable for high frequency applications such as variable frequency speed control systems.
(6) Stability and reliability
The switching and control of thyristor is based on physical principle, so it has high stability and reliability. It is not susceptible to external interference or temperature changes.
(7) Energy saving and efficiency
Because of the fast switching speed of thyristors, fast current switching can be realized in the circuit, thus reducing energy loss and improving the efficiency of the circuit.
