Latest SeaRAQ Board Provides Eight Isolated Differential A/D Inputs

Sealevel continues to increase the expansion capabilities of Relio R3 and Relio R4 industrial computers with the latest SeaRAQ 6513 expansion module. The new board adds eight general purpose 16-bit differential A/D input channels. Each channel can be individually software-configured for +/-10 VDC, +/-5 VDC, +/-1 VDC, +/-0.5 VDC, +/-0.15 VDC, as well as 0-25 mA current mode. The current loop receiver inputs are ideal for interfacing a wide variety of industrial process control and test equipment that use 4-20 mA signaling.

For maximum protection from damaging external voltages commonly found in industrial environments, the 6513 expansion board includes 1500 VAC of field-to-logic isolation.
