Open Collector
• Maximum switched voltage is 32VÎ
(dc)
• 400mA, maximum open circuit volt-
age of 25VÎ
(dc), typical 8VÎ (dc)
at 80mA
• Maximum output sink current per
output is 1.5A (external class 2 or
*SELV supply required)
• Total sink current for all outputs not
to exceed 8A
• Do not connect outputs in parallel
• *Safety Extra Low Voltage
Switched DC
• User selectable voltage, 5VÎ (dc) at
130mA or 19 to 22VÎ (dc) at 80mA

Digital Output - Switched DC Wiring Example
Note:
As a switched DC output; this output is a constant current output delivering 750 mW, cur-
rent limited to 150 mA. The internal supply is 5V(dc) open circuit. Pin Z1 is shared to all
digital outputs. This type of output is meant to drive solid state relays, not mechanical
