The OP5351 features 32 digital input channels operating at 5V (CMOS/TTL) or 3.3V (LVTTL).
Main Features
The 32 channels are grouped into two banks of 16 channels each.
The signals of each bank are made available to the user at one DB37F connector of the chassis in which the module is installed.
The voltage input for each bank is configurable for either 5V (CMOS/TTL Logic ) or 3.3V (LVTTL)
The OP5351 is galvanically isolated to real environment signals, providing protection to the simulator from damaging voltages.
Channel description
Each channel implements the circuit shown below:
Voltage Jumper Settings
Each group of 16 channel can be configured for 5V or 3.3V operation, using the jumpers P3 and P4:
P3 | CH00-15 (VIN_ISO1) |
| |
P4 | CH16-31 (VIN_ISO2) |
|
Typical Use Cases
The card is ideal for interfacing with devices operating at low voltage.

TTL signals are not recommended for long-distance data transmission. We recommend using this board with cable lengths no longer than 1.5 meters (5 ft). When using longer lengths, OPAL-RT recommends terminating the lines to avoid over/undershoots or using alternative transmissions, such as differential mode (e.g: LVDS OP5355-3, RS422 OP5356-5 [5V] or OP5355-3 [3V3]). For details on how to terminate the lines and to interconnect equipment with the OP5351 board, refer to the WP CMOS/TTL opal RT_rev 1.0. |
