GE VMIVME-111 64 bit High Voltage Digital Input Board

GE VMIVME-111 64 bit High Voltage Digital Input Board

Product Overview

VMIVME-111 is a 64 bit high-voltage digital input board with built-in testing capabilities, compliant with the VMEbus specification, and featuring a dual height European card design. It is suitable for scenarios that require monitoring multiple digital input signals and is compatible with the intelligent I/O controller series of GE Fanuc embedded systems. It supports hot swappable replacement and is software compatible with VMIVME-1110.

Core Features

Equipped with 64 bit differential or high-voltage digital input.

Each group of 32 inputs can be monitored through jumper selection: contact closure, voltage source, current absorption, or differential signal.

An open circuit can provide logic 0 or (jumper optional) logic 1.

Equipped with input filter options.

The onboard built-in testing logic is used for fault detection and isolation.

The front panel is equipped with a fault LED indicator light.

Users can choose to input a voltage threshold (1.25 to 66V).

Compatible with RS422/RS485 differential line receiver, providing ± 7V noise immunity.

Supports 8-bit, 16 bit, or 32-bit data transmission.

Adopting high reliability DIN type I/O connectors.

By using the corresponding suppression panel (such as VMIVME-3451), optical isolation can be achieved, which meets the surge protection requirements of ANSI/IEEE STD C37.90.1-1982.

Ordering Options

A=0 (option reserved for future use).

B is the input filter/terminator option: 0 is with input filter/terminator (the input filter/terminator circuit can provide a series RC terminator or input filter through jumper selection, with a time constant of 0.14ms, used for receivers compatible with RS422/RS485); 1 is without input filter/terminator; 2 is a 2 μ s filter; 3 is a 10 μ s filter; 4 is a 5ms filter; 5 is a 1ms filter.

C=0 (option reserved for future use).

Connector data

Compatible cable connector: Panduit No.120-964-435.

Strain relief: Panduit No.100-000-072.

Printed circuit board plug connector: Panduit No. 120-964-033A (also known as ITW/Pancon).

Functional characteristics

Compatibility: Compatible with VMEbus specifications, dual height appearance.

Input connector type: Dual 64 pin connector - DIN 41612.

I/O organization: 8 input ports, each 8 bits wide, addressable to any address within the short monitoring and/or short non privileged I/O mapping, control and status register (CSR) addresses can be independently selected.

Addressing scheme: 8 ports can be individually addressed on 8-bit, 16 bit, or 32-bit boundaries, 1 CSR can be addressed on 8-bit boundaries, and 13 jumpers provide unlimited short data I/O address mapping options.

Differential signal input characteristics: The common mode input voltage range is -30 to+66V, and the input sensitivity is ± 100mV within the common mode range of -7 to+12V. The input impedance is high (33k Ω).

Single ended signal input characteristics: high input impedance (33k Ω), threshold accuracy of 1% (typical value) across the entire 66V range.

Signal conditioning input filter terminator option: A board with input signal filtering circuit can be ordered. For differential input, the circuit consists of a series resistor and a capacitor, which are connected across the signal input terminals; For single ended inputs, this circuit provides users with the option to select an input debounce filter with a time constant.

Built in testing: Designed with internal self-test logic to test all active components, providing special output registers to generate 16 bit data words for health testing during real-time or offline operations. CSR provides special test mode bits to enable the output test registers to drive differential receivers. The front panel fault LED lights up when powered on and can be turned off under program control after successfully completing user-defined diagnostics.

Physical/Environmental Specifications

Threshold voltage

When R=3.3k Ω, the threshold voltage formula is

Vt=[(V−1.25)(.91)]+1.25

The Vt values corresponding to different voltages are as follows: 1.25V corresponds to 1.25V, 5V corresponds to 4.7V, 12V corresponds to 11V, 24V corresponds to 22V, 28V corresponds to 25.6V, 48V corresponds to 43.8V, and 66V corresponds to 60.2V.

When R=33k Ω, the threshold voltage formula is

Vt=[(V−1.25)(.51)]+1.25

The Vt values corresponding to different voltages are as follows: 1.25V corresponds to 1.25V, 5V corresponds to 3.2V, 12V corresponds to 6.7V, 24V corresponds to 12.9V, 28V corresponds to 14.8V, 48V corresponds to 25.1V, and 66V corresponds to 34.3V.
