Product No. : INNIS21
Product Type : Network Interface Module
Power requirements: +5 VDC at 825 mA; 4.1 W/ +5 VDC at 1.1 A; 5.5 W
System capability Cnet (INFI-NET): Over 62,000 nodes in the system; 250 Cnet-to-Cnet interface nodes; 250 nodes on a single network in any combination of Cnet-to-HCU and Cnet-to-computer interfaces
Communication rates: 10 Mbaud, 2 Mbaud, or 0.5 Mbaud
The INNIS21 Network Interface Module is the front end of every Cnet communication interface.
It is the intelligent link between a node and the Cnet. In this case, it works in conjunction with the INNPM22 module.
The INNIS21 module allows any node to communicate with any other node within the Symphony system.
The INNIS21 module is a single printed circuit board that occupies one slot in a module mounting unit (MMU).
The circuit board contains microprocessor based Communication circuitry that enables it to interface with Cnet, and with the INNPM22 module over a dedicated I/O expander bus segment.

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.
