This counter is in two variants, HED261-R with reflective display and HED261-T with LED
backlight. Connection is via 2 sets of 3 pins at 0.1 inch pitch, spaced as shown.
The unit is fixed to the panel using the two spring clips which are integral to the housing.
The unit is the correct way up when the pins are at the bottom.
It can be powered from a higher DC voltage using the external circuit shown. For a 5v
supply omit the regulator. Use the regulator for a supply in the range 8 - 30v. The
regulator accommodates the different current requirements for the reflective and backlight
models.
Note:
This product is ideally suited to battery powered applications. Should the product be used
in a circuit where an external power source is used, then the complete system will require
separate approval to meet the CE standards.
Any signal cables connected to this device must not exceed 30 metres in length.
If signal cables are installed that are routed outside the building, it will be necessary to
install additional surge protection devices.
