The OP5320 is one of a range of signal conditioning modules for the OP5000 FPGA I/O system from Opal-RT Technologies. A single module allows up to 16 I/O signals to be converted to a level required by either an analog or digital I/O board, or the external hardware, depending on the signal direction. Given that the OP5210 carrier can accommodate up to two mezzanine modules, it allows up to 32 signals to be conditioned per carrier.

The OP5320 handles voltage levels up to 100 Vdc in input, allowing a greater level of voltage match an input module, that can be used to provide a means of applying an offset voltage to digital I/O thus allowing bipolar signals to be connected to the OP5311 and OP5312 modules.

The OP5320 can also be used to condition analog and digital signals for third-party I/O hardware, such as National Instruments and Acromag.
