Product Description
The D841 and D850 are super bright RED LED displays that feature alpha-numeric characters allowing for improved clarity in messaging. This is ideal for concrete batching plants or custom site management applications where non-weight related messages such as material names need to be displayed. The D841 and D850 supports the majority of printable ASCII characters. These displays are part of Rinstrum’s range of remotes that are built for both indoor and outdoor industrial applications.
Visibility:
- D841 - >50m (164 feet) at 120 degrees viewing angle.
- D850 - >70m (230 feet) at 120 degrees viewing angle.
Unit Switching**:
- D841 and D850 allows for kg, lb, t, g, tn and oz units to show on display.
Traffic Lights**: The D841 traffic lights (50mm/2 inch round red and green) can be driven from discrete inputs or directly via the communications protocol. The universal inputs will accept clean contact switches or voltages 5-24VDC to control the traffic lights.
Decimal Point:
The decimal point will be displayed between digits as two LEDs in the D841 and the D850. The decimal point does not affect number of digits displayed.
Scrolling Messaging (D841 only):
The D841 can be fitted with K802 firmware for moving messages to interface with a PC or equivalent device. With a fixed format text string length of up to 150 characters it is ideal for providing instructional messages to truck drivers or equipment operators. (K802 firmware option is factory fit only).
** Where unit switching, traffic lights and annunciators are support in the protocol.
Smart Weighing
