SAM Based Safety Arming Mechanism (SAM) AAD/PDV

SAM-AAD is an Electronic Control Units (ECU) designed using Xilinx CPLD. All the control inputs are Opto-isolated and fed to the CPLD for timing and control signal generation. On release of Power on Reset, the SAM goes into Checkout mode and checks the health of ECU. Once OBC-I command is received and health status is fine, then SAM enters into Flight mode if not, it continues to be in Checkout mode until all the errors are cleared. In the checkout mode SAM works with External supply.

It consists of two PCBs:

a) Logic Card
(b) Interface Card.

The Logic card controls the operation of squib firing and ignition circuitry with appropriate timing based on the input signals. The Interface card contains all the connectors that are required to interface with the other external circuitry.

SAM Based Safety Arming Mechanism (SAM) ASTRA

SAM-ASTRA is an Electronic Control Unit (ECU) designed using Actel’s FPGA. All the control inputs are Opto-isolated and fed to the FPGA for Timing and Control signal generation. On release of Power on Reset, the SAM goes into Checkout mode and checks the health of ECU. Once the health status is fine SAM will enter into Mission mode, if not it continues to be in Checkout mode until all the errors are cleared. SAM scans for Lift off signal and acceleration ‘g’ signal for 5 seconds. In the Checkout mode SAM works with External supply.

It consists of three PCBs:

(a) Logic Card
(b) Interface Card and
(c) ADXL card.

The Logic card controls the operation of squib firing circuitry and ignition circuitry with appropriate timing based on the input signals. The Interface card contains all the connectors that are required to interface with other external circuitry.

SAM Based Safety Arming Mechanism (SAM) NAG/ HELINA

SAM-NAG/ SAM-HELINA are Electronic Control Units (ECU) designed using Xilinx CPLD. All the control inputs are Opto-isolated and fed to the CPLD for timing and control signal generation. On release of Power on Reset the SAM goes into Checkout mode and checks the health of ECU. Once the health status is fine, SAM will enter into Flight mode if not it continues to be in Checkout mode until all the errors are cleared. In checkout mode SAM works with External supply.

It consists of two PCBs:

a) Logic Card
(b) Interface Card.

The Logic card controls the operation of squib firing circuitry and ignition circuitry with appropriate timing based on the input signals. The Interface card contains all the connectors that are required to interface with other external circuitry.

SAM Based Safety Arming and Sequencing Unit (SASU) PINAKA

SASU-ELM is Electronic Control Units (ECU) designed using Microchip Microcontroller. All the control inputs are Opto-isolated and fed to the Microcontroller for timing and control signal generation. On release of Power on Reset the SASU goes into Self Diagnosis mode and checks the health of ECU. Once the health status is fine, SASU will enter into Flight mode if not it continues to be in Checkout mode until all the errors are cleared. In checkout mode SASU works with External supply. The execution time of the Missile is set externally through RS422 communication link. The allowable set time is in between 20 to 200 seconds.

It consists of Five PCBs:
a) Processor Card
(b) Interface Card
(c) Power supply card
(d) Sensor Block PCB and
(e) Thermal Battery PCB.

The Processor card controls the operation of squib firing circuitry and ignition circuitry with appropriate timing based on the input signals. The Interface card contains all the connectors that are required to interface with other external circuitry.
