12 input 4 output expander with Modbus
The AMB-12I-4O is an input/output interface module to Modbus RTU over RS485. It has 12 isolated digital input with high voltage range up to 30VDC and 4 relay output with 5A 230V range and NO contacts. The power supply range is 8 to 36V and accept DC or AC voltage. The use of DC / DC technology for supplying relays enables a wide range of supply voltages.
The Modbus address and baud rate is configurable by DIP switch. Each input and output has activity indicator and module also has indicator of activity. The use of 32-bit ARM core provides fast processing and quick communication.
The Modbus input and output extension is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment and/or applications with high communication requirements.
