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.
