 Hardware Interface for validATE
Validation in an Automated Test Environment
Accutest has developed a scalable hardware interface for signal conditioning within validATE - a flexible hardware-in-the-loop system which improves testing accuracy and reduces testing time and costs.
The interface includes:
 validATE Low Power Relay Card
This board provides 16 channels of digital outputs. Each channel has opto-isolation to isolate the TTL signals from the higher current signals. The relays are SPDT and have three connections brought to the front connector.
Card Specification:
- 16 Relays
- Up to 1A per Relay, up to 15A per card
- Up to 30v at A1
- Each Relay can be configured to switch power or ground
- Up to 6 Low Power Cards can be added to a DIO96 Configuration (96 Relays)
- Up to 2 Low Power Cards can be added to a 6025E Configuration (32 Relays)
- 3U Euro card (100mmx160mm)
- 6HP
- 48 Way IEC 41612 Type F Backplane Connector
- 50 Way DSUB
 validATE Resistor Ladder Card
This board provides a resistance level that is controlled via 16 digital output lines. There are three different configurations available, i.e. 4-bit ladder, 8-bit ladder or a 16-bit ladder. This allows combinations to be produced of 4x4-bit ladders, 2x8-bit ladders or 1x16-bit ladder. Also it is possible to have 2x4-bit ladder and 1x8-bit ladder, etc. Each ladder is capable of having a single fixed resistance in addition to the switch-able resistances. All the resistors that make up the ladder are mounted in DIL carriers so that they can be changed easily. The board can have 4x12Way carriers or 2x24Way carriers.
Card Specification:
- From 4x4-bit Reisitor Ladders to 1x16-bit Resistor Ladder
- Up to 60v at 1A
- Additional ‘offset' Resistors can be added to each bank of 4 Resistors
- Up to 6 Resistor Ladder Cards can be added to a DIO96 Configuration
- Up to 2 Resistor Ladder Cards can be added to a 6025E Configuration
- 3U Euro card (100mm x 160mm)
- 6HP
- 48 Way 1EC 41612 Type F Backplane Connector
- 25 Way DSUB
 validATE Digital Input Card
This board allows 8 channels of opto-isolated digital inputs. The card is intended to be plugged into the two 8 bit channels on the backplane, but can be used in the 16 bit channels if required. This card also has the capability to include a pull-up or a pull-down resistor mounted on the board. Feedback can also be provided to the user in the form of 8 LEDs that are front mounted.
Card Specification:
- 8 Digital Inputs
- Up to 30v Input
- Up to 7 Digital Input Cards can be added to a DIO96 Configuration (56 Inputs)
- Up to 3 Digital Input Cards can be added to a 6025E Configuration (24 Inputs)
- 3U Euro card (100mmx160mm)
- 6HP
- 48 Way IEC 41612 Type F Backplane Connector
- 15 Way DSUB
- 8 Font Mounted LEDs
 validATE High Power Relay Card
This board offers 8 channels of digital outputs. Each channel has opto-isolation to isolate the TTL signals from the high current signals. The relays are SPDT and have all three connections brought to the front connector. This is considered an 8-bit digital card and as such can be used in either slot 1 or 2 on the backplanes of either system although it is also possible to connect in into any 8 or 16-bit digital slot.
Card Specification:
- 8 Relays
- Up to 5A per Relay, up to 15A per card
- Up to 30v at 5A
- Each Relay can be configured to switch power or ground
- Up to 7 High Power Cards can be added to a DIO96 Configuration (56 Relays)
- Up to 3 High Power Cards can be added to a 6025E Configuration (24 Relays)
- 3U Euro card (100mmx160mm)
- 6HP
- 48 Way IEC 41612 Type F Backplane Connector
- 37 Way DSUB
Additional card types can be supplied in accordance to customer specification.
