BAS-3050 BAS-3051 8-ch DI, 8-ch DO Expansion Module 16-ch DI Expansion Module Features 24 VDC or 24 VAC input 3000 VDC isolation protection Supports 1 kHz counter input and 1 kHz frequency input (2 channels) Supports PWM output (2 channels) (BAS-3050 only) Supports Modbus /RTU Protocol BAS-3050 BAS-3051 RoHS COMPLIANT 2002/95/EC Introduction BAS-3050/BAS-3051 expansion I/O modules can be stacked on the DDC controller, or can serve as remote standalone I/O modules through an RS-485 network. These expansion I/O modules add both scalability and flexibility to Advantech BAS-3000 solutions. Like the DDC, I/O expansion modules can be programmed using the BASPro programming tool.
