Connecting bar code reader to MA 150 connection unit
The signals from the bar code reader are distributed in the machine decentrally via the MA 150 modular
connection unit. The following components can be connected to the MA 150 connection unit:
• BCL 92 series bar code reader
• Photoelectric sensor/diffuse sensor to activate the bar code reader
• Voltage supply
• Serial communication RS 232
NOTICE
Supply voltage!
A supply voltage of 18 … 30 V DC is necessary if connecting via the modular connection unit.
