General Description & Features
Connecting directly to its source sensor via simple pinout, each 5D module powers, conditions, isolates,filters, and scales its sensor's analog signal to a standardized 5-V or 10-V level, making it usable as high-quality input to a PC, PLC, or other device for further processing, display, recording, etc. Every standard and "S" Option 5D module delivers filtered analog output of ±0 to 5 VDC, while the corresponding "V" model produces ±0 to 10 VDC.
Two independent high-level, noise-free analog outputs
For all standard 5D models, one output signal is continuously available, while the other may be switched on and off by setting the logic state of an "enable" line (thus eliminating the need for an external multiplexer in multiple-module applications). For all "V" and "S" versions, both output signals are continuously available. Each output is a true analog signal path, with no digital time lag involved. With independently selectable low-pass analog filtering, separate outputs can be used for simultaneous local calibration/metering and high-speed data acquisition sampling.
High output accuracy over a wide temperature range
The traditional Daytronic benchmark for measurement accuracy (0.02% of full scale typical) meets or exceeds the competition, guaranteeing repeatable sensor signal integrity for amazingly stable readout and solidly dependable control action, even in the most electrically noisy environments (see individual 5D model specifications). Remote sense for long-cable applications yields true ratiometric measurements regardless of cable length. Software-based SYMMETRY and MIDRANGE LINEARITY corrections of the output signal further compensate for intrinsic sensor/cable errors.
A Simple, Flexible Mechanical Interface
A 5D module's extruded-aluminum case has guides for insertion into a housing. It also provides an edge screw boss for securing the unit independently to a fixture or clipping it to a European DIN standard 35-mm rail (the mounting holes are spaced to accommodate the standard JIT Component "JSDA" clip, available from Daytronic). Or it can be plugged into a "motherboard" backplane assembly (such as a Daytronic "5DMB") for multiplexing into an analog input device, via its Analog/Power/Communications Connector (standard DB25 or alternative screw-terminal).
For every "V-" or "S-version" 5D model, a 10-pin header for a Phoenix Style screw-terminal connector replaces the standard DB25 connector for the module's power, configuration, logic, and analog output wiring. Ensuring secure cable connections to individual 5D modules, this option is intended primarily for single-point or single-mount module applications. Since the logic "enable" line is not provided in this case, both analog outputs are continuously available for all "V" and "S" models.
The Daytronic Model 5DMB-16 cabinet-mountable motherboard accommodates up to 16 individual 5D modules with standard DB25 connectors, and typically serves as a front end for a PC with a 16- or 32-channel A/D card. With its simple "relay strip" design, the 5DMB-16 connects all power and communications lines in a single serial port, and provides pluggable screw terminals for all module outputs.
Configuration Software Makes Short Work of Module Setup
Communicating via RS232 link, the 5D Configurator software lets you define, store, edit, download, upload, and manage any number of "configurations" for a connected array of up to 16 independent 5D modules. It also lets you perform selected run-time operations, including both "absolute" and "two-point" calibration, sending standard mnemonic commands to a specific module, and activating a shunt calibration resistor (if present).
