OP7816 16 Digital Inputs Module
The OP7816 (also named OP7816-2) module features 16 digital input signals. The cards feature optical isolation of all the inputs. The card accepts input voltages between 5V and 50V, with a 30V maximum reverse protection. In the typical configuration, the 16 channels are routed via the mid-plane of the chassis to the Primary FPGA card (OP7161-1 or OP7170-1) which performs acquisition of the channels' state. Alternatively, if a Secondary FPGA card (OP7161-2 or OP7170_2) is installed in the front slot corresponding to the back slot where the card is installed, the acquisition of the channels can be performed by this secondary FPGA card.
