Modbus data acquisition I/O, D1-40A-x
The D1-40A-V and D1-40A-I Modbus data acquisitions modules are available with 6x 0-5VDC or 6x 4-20mA inputs. An A/D converter with 16 bit resolution is used for the analog to digital conversion. The modules have a RS485 or RS422 interface and the communication protocol is Modbus ASCII or RTU and can be mounted on a DIN-rail.
