The D3000M series digital to analog output modules contain an isolated 12-bit digital to analog converter that is scaled to generate DC voltage or current signals commonly used in the process control, production test and motion control industries. Six different voltage output ranges and two different current output ranges are available.

The 12-bit digital to analog converter is controlled using either the Modbus RTU or DGH ASCII serial protocol.  The Modbus RTU protocol is enabled or disabled by commands and the module supports standard Modbus RTU read and write functions. The commands are received through either an RS-232 or RS-485 serial port.

The D3000M includes three discrete digital inputs that can accept direct contact closures from switches or relays.  Making them ideal for monitoring On/Off signals like cabinet door status or manually controlling the analog output signal at a remote module location.

The D3000M series advanced features include a user-selectable analog output slew rate and a communications watchdog timer. The communications watchdog timer can be used to set the analog output to a “safe” level in the event of a communications loss.

The D3000M series modules are cost effective solution for control applications that require a simple step function output.  The analog output signals can be used to control annunciators, actuators or other hardware that requires a control input signal.
