6.5 OUTPUTS
6.6 PCIe Bus Specifications
Compatibility
Conforms to PCI Express Base Specification, Revision 2.1
Line Speed
Gen1 (2.5Gbps) available through PCIe connector
Lane Operation
1-Lane
4K Memory Space Required
One Base Address Register (BAR)
Output Channel Configuration
32 isolated Solid State Relay (SSR) output supporting AC or DC (high or low
side switching) operation. SPST-NO, “1 Form A” contacts.
“OFF” Voltage Range
0 to ±60V DC or peak AC.
Output “OFF” Leakage Current
1uA maximum
Output “ON” Current Range
150mA maximum continuous (up to 1A total per port). Outputs are NOT
current limited and may need external current limiting circuitry to ensure
current does not exceed 150mA (R = V/I). When choosing a current limiting
resistor, also be sure not to exceed to maximum power rating for that
resistor (Power = V
2
/R).
Ouput ON resistance
8Ω, maximum (25°C)
Turn-On Time
1ms typical, 2ms maximum
Turn-Off Time
0.2ms typical, 1ms maximum
Reset Condition
All output SSR’s OFF
Output Pull-up Resistors
Pull-up resistors are depopulated on standard model for high side switching
applications. The 0603 surface mount pull-ups can be installed by factory at
customer request for low side switching applications. Calculate resistor
power for user supplied voltage (Power = V
2
/R). Limit power to 0.2W per
resistor (30.6V max @ 4.7KΩ). Install a lower value (check power) to obtain
faster, stronger pull-up.
TTL Compatibility
Yes, used as a low side switch can sink 32mA at 0.2V; source 500uA at 2.4V
with a 4.7k ohm pull-up to 5V supply.
