software set. Default max current 1.5A.
• Backlight on – additional 55mA.
• External fusing should be 2A.
Digital Inputs:
• To operate pull to ground or may be driven high or low. High level from 5-24V. Low Level
less than 1V.
Analog Inputs:
•
2. 0-16 V. Input impedance approx. 50K. Slope and offset configurable (e.g. to support 1-5V
or 1-10V).
