JLCooper eBOX io Real World Interface

The JLCooper eBOX io a companion to eBox and gBOX. It converts 8 GPI outputs to electrically isolated, relay outputs. The eBOX io also accepts 8 GPI inputs via opto-isolated inputs. eBOX and gBOX GPI inputs and outputs are CMOS compatible circuits. The CMOS GPI inputs require that the input signals be 0 to 5 volts and referenced to ground. The CMOS GPI outputs can deliver 0 to 5 volts at up to +/- 6mA and referenced to ground. In most cases, this will be compatible with your equipment. However, in some cases, equipment may not be compatible with 0 to 5 volts. In this case, the eBOX io can be added. Each eBOX io buffers 8 inputs and 8 outputs. Inputs are buffered with an optoisolators and outputs are buffered with a dry relay contact.
