4.2.3 Electrical Characteristic

Each DC output (pin 1-6) is isolated by open collector photocouplers. Output voltage of each line is decided by pull-
up voltage of Handler interface. The pull-up voltage is provided by the external voltage (EXTV: +5V to +24V).
Elecrical characteristic of DC isolated output see Table 4-3.
