8-channel analog output board | Model 7405

Model 7405 8-channel analog output board
  • Eight 12-bit analog outputs
  • Channels independently configurable for +10V / 4-20mA
  • Outputs automatically reset to 0 volts or 4 mA
  • 0-5V / 0-10V output options

Model 7405 is a legacy product and is not recommended for new designs. Legacy products are available but may have lead times up to 12 weeks and minimum order requirements. Use our Product Finder to find a comparable product or contact our Design Support Team.


Model 7405 is an STDbus board that generates eight analog outputs. Each output channel may be independently configured for either voltage or current output mode. In both modes, output amplitude is a linear function of the programmed digital value.

Model 7405 application


Voltage output

When programmed for voltage out, a channel will generate an output between -10 volts and +10 volts. Full scale output ranges of 0 to 5 volts and 0 to 10 volts are available as factory programmed options.

4-20 mA

Configuring a channel for current output allows driving a 4-20 mA current loop. In this mode, a channel varies its output voltage in order to maintain a constant output current.


In response to a reset, all channels are automatically reset to the appropriate zero-output condition. Voltage-mode channels are initialized to zero volts and current-mode channels are initialized to 4 mA out.


Output channels are accessible at a 40-pin header at the edge of the 7405 circuit board. Convenient screw terminal breakout boards are available to simplify field wiring.

I/O ports

The 7405 occupies two consecutive addresses in the STD bus 8-bit address space. The base address may be jumper-programmed to any even address.

Termination boards

Sensoray offers a variety of breakout boards that convert flat cable connections to screw terminals.

Model 7409TB is a low cost 2x4.6 inch terminal board with a 40-pin flat cable connector on its backside to facilitate panel mounting. Field wiring is made on the front side.

Model 7409TC is a 3.8x5.4 inch terminal board with eight removable terminal blocks, one for each output channel. It has a prototype area for constructing custom circuits.

Model 7409TDIN consists of a 7409TC supplied with snap-rails for DIN rail mounting.
