eBOX io

Real World Interface

Relay outputs and opto-isolated inputs for eBOX

eBOX io is 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 opto-isolators and outputs are buffered with dry relay contacts.

All connections are made on the rear panel via detachable Weidmüller terminal block connector with screw terminals. Front panel LEDs indicate status for easy monitoring. eBOX io is a half rack unit and fits alongside eBOX in a single rack space. It can be rack mounted using “JLC-RACKTRAY” shown above.

eBOX io comes with a pair of cables that allow you to connect a single eBOX io to an eBOX. Up to 3 eBOX io’s can be cascaded to convert all 24 eBOX GPI inputs and outputs. To connect two or three eBOX io’s to a single eBOX, order the optional “EBOX-I/OEXPCAB Kit”, which includes a pair of special cables as shown above.
