Pocket AL I/O QB QB Installation

Optoinsulated digital inputs

In case you use optoinsulated inputs, it will be necessary to use an external power voltage in

the range between +5V and +32Vcc.

Connect a pin of the optoinsulated digital input to positive sensor pin, then connect the other

pin of the optoinsulated digital input to negative sensor pin.

E.g.

OPT1 pin11 -> from +5Vdc to +32Vdc of sensor

OPT1 pin12 -> GND sensor

Relay outputs

The two Relay outputs of Pocket AL I/O QB allow the control of the devices that can be enabled

and disabled when a switch is closed (i.e. Light, Alarm, Logic port, etc.).

When connecting your devices, keep into consideration the maximum voltage and the maximum

power: 60Vcc – 1A.

Analog Inputs

Pocket AL I/O QB supports both active and passive 4-20mA sensors.

Passive Sensors

Pocket AL I/O QB manages passive sensors that have a maximum power of 12V. Connect the sensor between pins 3 and 4 or

between pins 5 and 6 of the 6 PIN terminal board.

Active Sensors

Pocket AL I/O QB manages also active sensors that require a special power.

You can use 1 and 6 GND ground pins present on 20 pins terminal board. The 12Vdc pin will be active after you conﬁgure the

analog input.
