Abaco Systems / VMIC VMIVME-2210 通过两个 96 针 DIN 连接器为用户提供 64 个 One Form C （SPDT） 触点。这些继电器是磁闭锁型，这意味着一旦设置了触点，它将保持设置状态（即使从继电器中断开电源），直到它被复位。所有三个接触点均通过连接器引出。它们是 N.O.（常开）、N.C.（常闭）和公共接触点。N.O. 和 Common 可用于创建一个 A 型触点，而 NC 和 Common 可用作一个 B 型触点。常开触点位于连接器的 A 行，公共触点位于连接器的 C 行，如图 1 所示。这种布置允许将 64 芯电缆用于 A 型开关。

VMIVME-2210 装有双极继电器，但只有一极引出给用户。另一个极点由内置测试 （BIT） 逻辑使用。控制数据寄存器或 NC 极点的状态在电路板读取访问期间读取。控制寄存器与继电器位于同一地址。这允许用户监控用户联系人和控制寄存器的状态。由于读极和用户极由同一线圈控制，BIT可以通过第二极的N.C.触点监控用户的触点。

N.C.触点为写入数据寄存器的逻辑触点提供逻辑触点。这提供了来自接触式 BIT 逻辑的正数据反馈。当逻辑 1 写入控制寄存器时，它会激活继电器，从而导致常开触点闭合和常闭触点断开。读取触点 BIT 逻辑时，将返回逻辑 BIT。

控制数据寄存器也受到监控，因为继电器需要很长时间（最大 7 ms）才能更改其触点。电路板的 VMEbus 访问执行速度如此之快，以至于继电器似乎出现故障，从而导致错误的结论。为了防止这种情况，用户可以检查数据寄存器的状态，而不是等待继电器的触点闭合。

该板使用闭锁继电器，当断电时保持其状态。这意味着闭合的触点将保持关闭状态，直到命令打开。

Prevent relays from changing during power-on/power-off

Abaco Systems/VMIC VMIVME-2210 provides users with 64 One Form C (SPDT) contacts through two 96-pin DIN connectors. These relays are magnetic latching type, which means that once the contact is set, it will remain set (even if the power is disconnected from the relay) until it is reset. All three contact points are led out through connectors. They are the N.O. (normally open), N.C. (normally closed), and common contact points. N.O. and Common can be used to create A type A contact, while NC and Common can be used as a type B contact. Normally open contacts are located on row A of the connector, and common contacts are located on row C of the connector, as shown in Figure 1. This arrangement allows 64 core cables to be used for type A switches.

The VMIVME-2210 is equipped with a bipolar relay, but only one pole is drawn out to the user. The other pole is used by built-in test (BIT) logic. The status of the control data register or NC pole is read during board read access. The control register is located at the same address as the relay. This allows users to monitor the status of user contacts and control registers. Since the reader and user poles are controlled by the same coil, the BIT can pass through the N.C of the second pole. Contacts Monitor the user's contacts.

The N.C. contact provides logical contacts for the logical contacts that write to the data register. This provides positive data feedback from the touch BIT logic. When logic 1 writes to the control register, it activates the relay, which causes normally open contacts to close and normally closed contacts to break. When the contact BIT logic is read, the logical BIT is returned.

The control data register is also monitored because the relay takes a long time (up to 7 ms) to change its contacts. The board's VMEbus access performed so fast that the relays appeared to malfunction, leading to false conclusions. To prevent this, the user can check the status of the data register instead of waiting for the contact of the relay to close.

The board uses a latching relay to maintain its state when power is cut off. This means that closed contacts will remain closed until the command is opened.
