• Connect pin "Earth" of the TCNM-ACBB1 connection box to a good earth ground
•
For direct connections, connect the cable shield to the locking ring nut of the connector
3.6.2 Inputs
There are two opto-isolated polarity insensitive inputs available on the M12 17-pin connector of the reader: Input 1 (External
Trigger) and Input 2, a generic input. See
Inputs
on page 29 for more details.
The electrical features of both inputs are:
INPUT | V AB | Minimum | V
AB
| Maximum I
IN
Maximum
Open 0 V 2 V 0 mA
Closed 4.5 V 30 V 10 mA
The relative pins on the M12 17-pin connector are:
Pin Function
1 Power Supply input voltage +
2 Power Supply input voltage -
3 Input 2 B (polarity insensitive)
5 External Trigger B (polarity insensitive)
6 External Trigger A (polarity insensitive)
13 Input 2 A (polarity insensitive)
3.6.3 Outputs
Three general purpose non opto-isolated but short circuit protected outputs are available on the M12 17-pin connector.
The pinout is the following:
Pin Function
9 Configurable
digital output 1
8 Configurable digital output 2
16 Configurable digital output 3
2 Power Supply Input Voltage -
The electrical features of the three outputs are the following:
Outputs
3 NPN/PNP/Push-Pull software selectable, reverse polarity and short circuit protected outputs available (2 Opto-isolated outputs instead if using
TCNM-ACBB1, see
Outputs
on page 33 for specifications)
Maximum Current: 100 mA maximum
Output Saturation Voltage (in PNP or NPN mode): < 3 V at 100 mA
Maximum load device voltage drop (in NPN mode): 30 V
The output signals are fully programmable being determined by the configured Activation/Deactivation events, Deactivation
Timeout or a combination of the two. For further details refer to the Help On Line page for the Output Setup step in Barcode
Manager.
CAUTION: For NPN output connections, the external interface voltage (Vext) must not exceed the ABR
power supply source voltage (Vdc) otherwise correct output functioning cannot be guaranteed.
