Each SCM5B39 current output module provides a single channel of analog output. The track-and-hold circuit in the input stage can be operated in a hold mode where one DAC can supply many output modules, or a track mode where one DAC is dedicated to each module. In addition to the track-and-hold circuit, each SCM5B39 current output module provides signal buffering, isolation, filtering, and conversion to a high-level current output.

Setting of the track or hold mode is controlled by the logic state of WR EN\, module pin 23. When pin 23 is low, the track mode is enabled. If pin 23 is high, the hold mode is enabled. The module is designed with a completely isolated computer side circuit which can be floated to ±50V from Power Common, pin 16. This complete isolation means that no connection is required between I/O Common and Power Common for proper operation of the track and hold circuit. For a low state, simply connect pin 23, the Write-Enable pin, to I/O Common, pin 19.

The SCMPB02 and SCMPB06 backpanels allow host computer control of the WR EN\ control line, which allows multiplexing of one host DAC to up to 64 SCM5B39 current output modules. During power-up, the output remains at 0mA for 100ms on all models except the SCM5B39-07 current output module, which allows the track-and-hold circuit to be initialized.

A special circuit in the output stage of the SCM5B39 current output module provides protection against accidental connection of power-line voltages up to 240V AC on all models.

A wide range of backpanels, DIN rail mounting options, cables, racks, power supplies and other accessory items are available for the SCM5B39 current output module.
