The DI-725 is a 32-channel analog expansion unit for DI-720, DI-722, and DI-730 instruments. It is available in two models; base measurement range and extended measurement range. The base model features 32 differential analog inputs, a programmable gain amplifier with gain selections of 1, 2, 4, and 8; and a ±10 volt full scale measurement range (at a gain of 1). The extended measurement range model also features 32 differential analog inputs and a programmable gain amplifier with gain selections of 1, 2, 4, and 8, but it has a ±20 volt full scale measurement range (at a gain of 1).
The DI-725 derives its power from the host DI-720, DI-722, or DI-730 instrument, therefore no additional power supply is required. In return for the 32 expansion channels it provides, each DI-725 consumes two channels from its host instrument. For example, when connected to a DI-720, the combination delivers 62 total channels (30 are still available on the host DI-720). When connected to a DI-730, the DI-725 adds 32 high level differential inputs to the host's 8 wide measurement range inputs for a diverse blend of 40 total channels. A total of 240 channels may be configured using multiple DI-725's.
The DI-725 comes in the same sleek package as the DI-720, DI-722, and DI-730, which measures only 9 × 7.29 × 1.52 inches. Access to the analog inputs is provided through dual 37-pin, D-type connectors. Supported accessories include the DI-205 I/O signal interface, the DI-705 I/O signal interface, the DI-706 I/O signal interface, and the CABL-4 BNC input signal interface cable.
The DI-725 is designed for cost-effective channel expansion for DI-720, DI-722, and DI-730 instruments. Based on US list price, the DI-725 lowers the per channel cost of the DI-720 from $37 to $30; and the DI-730 from $374 to $92. The differential inputs of the DI-725 allow it to connect to a wide range of voltage and process current signals. The base measurement range model offers the following programmable ranges per channel: ±1.25, ±2.5, ±5, and ±10 volts full scale. The extended measurement range model (DI-725E) offers the following programmable ranges per channel: ±2.5, ±5, ±10, and ±20 volts full scale. It may be used in place of the base model whenever a more electrically rugged solution with an expanded measurement range is required.
Optional stacking brackets (part #100671) allow the DI-725 to be stacked and mounted to the host DI-720, DI-722, or DI-730 instrument. The stacking brackets come complete with mounting hardware to make installation a snap. An optional stainless steel carrying handle (part #100690) is also available for convenient system handling.
These LED's indicate when power from the host instrument is applied, and when this power is inadequate for use by the DI-725.
Allows you to connect to a wider range of signals.
Allows selectable measurement ranges of ±1.25, ±2.5, ±5, and ±10 volts full scale (base model) or ±2.5, ±5, ±10, and ±20 volts full scale (extended range model) per channel.
Since the DI-725E's extended measurement range channels use an amplifier per channel, many custom ranges can be configured for minimal additional cost. Contact us with your special requirements and let us quote a system that perfectly suited for your application.
