The OP5351 features 32 input channels operating at 5V (CMOS/TTL) or 3.3V (LVTTL).

Main Features

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)
  • Place jumper over pins 1 and 2 to obtain +5V.
  • Place jumper over pins 2 and 3 to obtain 3V3

P4

CH16-31 (VIN_ISO2)
  • Place jumper over pins 1 and 2 to obtain +3V3.
  • Place jumper over pins 2 and 3 to obtain 5V


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.
