...................... Supply voltage
ZVS
................... SUSI supply voltage
ZCLK
.................. SUSI clock (or AUX5 unamplified) *)
ZDAT
................. SUSI data (or AUX6 unamplified) *)
GND
.................. Ground (0 V)
GPIO
.................. General input / output (max. +5 V / max. 3 mA)
VCC
................... +5 V / max. 15 mA
*) Unamplified function outputs: See supplement 3.
†
) The DH21A existists in two different hardware variants:
– Function outputs AUX3, AUX4: each 1,0 A
(connecting option -0/-2/-3/-4)
– Function outputs AUX3, AUX4: unamplified *)
(connecting option -5)
If necessary: Connect blue wire (common return conductor) to VS.
You can connect a buffer capacitor to ZVS (+) and GND (-).
