BAS-3018 BAS-3024 8-ch UI Expansion Module 4-ch UI, 4-ch AO, 4-ch DO Expansion Module Features 24 VDC or 24 VAC input Universal input supports 0 ~ 10 V, 0 ~ 20 mA, 4 ~ 20 mA, RTD, Thermistor (3K, 10K), and digital input Analog output supports 0 ~ 10 V, 0 ~ 20 mA, and 4 ~ 20 mA (BAS-3024 only) Supports PWM output (BAS-3024 only) Supports Modbus /RTU Protocol BAS-3018 BAS-3024 RoHS COMPLIANT 2002/95/EC Introduction BAS-3018/BAS-3024 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.
