Product Detail:
Microprocessor technology makes DigiTec’s D2800B series of digital controller the ideal solution for meeting the measurement, display and control requirements of industrial applications, OEM’s and system designers.
Models are available for voltage, and current with 3-1/2, 4, 4-1/2 digit displays. Each unit has field selectable 115/230VAC input power via internal jumper selection.
Four Separate Setpoint Limits: Four separate setpoints may be operator programmed to indicate “out of limit” conditions based on the display value. Each limit can be assigned a single relay output with option “C” installed. The setpoints can be programmed also to make the display flash when in the alarm condition.
Lockout Code for Security: To eliminate unauthorized changes by the operating personnel, any alteration of the instrument setup data requires entry of user security code for access.
Second Scale: This function allows the user to set a second scaling to the input. The input will then be displayed in two engineering units (typically for English/Metric displays).
Peak 1 and Peak 2: Peak 1 and peak 2 are both assignable to capture the maximum or minimum display value. They are assignable to any channel and the net or gross value. It can be reset through a front panel key or remote input. Capture rate is 10/sec.
DigiTec recognizes the importance of customer support. One aspect of this support is customized engineering to meet our customer specific market requirements.
