GE VMIVME-2210 64 channel latch or momentary relay board

GE VMIVME-2210 64 channel latch or momentary relay board

Basic characteristics

Equipped with latch contacts, it can maintain its state when powered off, and there are two versions: latch and non latch.

Provide 1 set of C-type contacts (SPDT) with 96 core cables and 1 set of A-type contacts (SPST) with 64 core cables, supporting 8-bit, 16 bit, or 32-bit data transmission.

Support real-time and offline fault detection and isolation, with a rated current of 2.0A.

It can prevent the relay from changing state during power on and off, and when used in conjunction with a matching surge suppression panel (such as VMIVME-3459), it complies with the ANSI/IEEE C37.90.1-1982 surge protection standard.

Ordering information

The meaning of each parameter in the ordering options: A represents the type of relay (0 is a latch relay, 1 is a non latch relay); B is the number of channels (0 is 64 channels, 1 is 32 channels); C is a reserved option (0).

Recommended P3 and P4 cable connection connector components: The matching connector for 96 pin IDC is ERNI No.913.031, and the 0.033-inch ribbon cable (96 pin large-scale termination) is ERNI No.913.049; The matching connector for the 96 pin discrete wire is Harting No.09 03 096 3214, the female pressure contact point is Harting No.09 02 000 8484, and the connector housing is Harting No.09 03 096 0501; The printed circuit board connector is ERNI No.913.216. The Harting crimping tool model is 09 99 000 0075.

Functional feature details

Basic function: Provides 64 C-type latch relay contacts through two 96 pin DIN connectors, with an additional set of normally closed contacts for built-in testing (BIT). The latch relay remains in state after power failure until a change command is received.

Contact configuration: C-type contacts include normally open (N.O.), normally closed (N.C.), and common contacts. Normally open and common contacts can form A-type contacts, while normally closed and common contacts can form B-type contacts. The normally open contacts are located in row A of the connector, and the common contacts are located in row C. This arrangement allows 64 core cables to be used for A-type switches.

Relay and BIT logic: Bipolar relays are used on the board, with only one pole leading out to the user and the other pole used by BIT logic. When reading the board, the status of the control data register or normally closed pole will be read. The control register and relay address are the same, and users can monitor the status of both user contacts and control registers simultaneously. Due to the fact that the reading pole and the user pole are controlled by the same coil, BIT can monitor the user contacts through the normally closed contacts of the second pole.

Control and feedback: When writing logic 1 to the data register, the normally closed contact provides logic 1, achieving positive data feedback for the BIT logic of the contact. Writing logic 1 to the control register activates the relay, causing the normally open contact to close and the normally closed contact to open. When reading the BIT logic of the contact, it returns logic 1. Due to the long time required for the relay state to change (up to 7ms), users can avoid misjudgment by checking the data register status instead of waiting for the relay contacts to close.

Compliance: Complies with ANSI/IEEE STD 1014-1987, IEC 821, and 297 VMEbus specifications, with parameters A24, A16: 3D/39, 2D/29: D32, D16, D08 (EO): slave equipment.

Addressing scheme: The base address of the board contains the board ID, with a 16 bit CSR above it. The output register is located on the next long word boundary above the CSR, and the contact register is located above the output register. The output and contact registers can be addressed as 16 8-bit bytes, 8 16 bit words, or 4 32-bit long words, located on any 128 bit boundary within the standard data or short monitoring/non privileged I/O space.

Board addressing: 20 jumpers are used to select the base address of the board, 1 jumper determines the address space (standard data or short I/O), 1 jumper selects monitoring, non privileged, or any access mode, and the remaining 18 jumpers set the base address of the board.

Non latch option: If the non latch option is ordered, a standard relay will be used, and the contact data will not be affected. However, when the power is cut off, the contacts will not remain in the state. Reset and power-off will cause the relay to return to the normal position (normally open contacts open, normally closed contacts closed), and other operations are the same as the latch version.
