485SDA10 Features

The 485SDA10 is a general purpose control module which operates through an RS-485 interface. The 485SDA10 offers 11 channels of 10-bit A/D (analog to digital), 3 digital inputs and 3 digital outputs. With these features, the module can be used to sense a variety of external conditions and to control a variety of devices.

The 11 A/D channels allow you to measure voltages from 0 to 5 Volts. The 3 digital inputs and 3 digital outputs are CMOS/TTL compatible. The A/D and digital I/O lines are available through a DB- 25S (female) connector.

The 485SDA10 connects to the host computer’s RS-485 or RS-422 serial port using terminal blocks. The address and turn- around delays are software programmable to allow use of multiple devices or connection to existing systems. The unit automatically detects baud rates from 1200 to 9600. A data format of 8 data bits, 1 stop bit and no parity is used.

Configuration parameters are stored in non-volatile memory. The configuration parameters consist of the module address, communication turn-around delay, and digital output power-up states.
