Built in testing (BIT) function

Test mode activation scenario: software control, onboard power on, after system reset

Test mode features: Relay driver disabled (safety precautions), special test data can be written and read back to test the data path to the relay driver, and the read back data is real data (non inverted)

Non testing mode (online operation)

Positive logic board: When the data bit of the corresponding relay in the data register is set to a specific logic, the relay is activated (normally open contact closed)

Negative logic board: When the data bit of the corresponding relay in the data register is set to a specific logic, the relay is activated

Read back data characteristics: The read back function of the output register is disabled, and the read back data is inverted data

Power on and reset states: configured as test mode, all data registers are in a specific logic state; For negative logic options, data initialization is required before removing the test mode condition, otherwise all relays will be activated

General specifications

Data transmission: Supports 8-bit, 16 bit, or 32-bit data transmission

Address scheme: Four ports can be addressed with 8-bit, 16 bit, or 32-bit boundaries in short I/O addressing, and accessed as corresponding bit width words

Address modifier code: Short monitoring and/or short non privileged I/O access can be selected through jumper, factory configured for short monitoring I/O access

Control and Status Register (CSR): Used to control the front panel fault LED, internal built-in testing functions, and enable/disable relays

Board address: Select jumper in short I/O memory mapping through address selection

Front panel: equipped with a fault LED, which lights up when powered on and can be controlled to turn off through a program

Physical/Environmental Parameters

Temperature: Operating temperature 0-55 ° C; Storage temperature -40-85 ° C

Humidity: 20% -80%, no condensation

Altitude: The working altitude can reach 10000 feet

Cooling method: forced air convection

Power requirement: 3.9A at+5V

Mean Time Between Failures (MTBF): 70540 hours (217F standard)

Ordering Options

Data polarity (A): 0 is negative logic ("0" excites the relay); 1 is positive logic ("1" excites the relay)

Contact protection (B): 0 indicates no protection; 1 is a contact protection suitable for 1A switch current, maximum 50VDC (R=5.6 Ω, C=0.1 µ F)

Other options: C=0 is a reserved option for the future; 2 is a contact protection suitable for 1A switch current and maximum 200VDC (R=22 Ω, C=0.1 µ F)

Connectors: The PC board connectors are AMP 554085-1 and AMP 554901
