Hardware settings:
• Six DIP switches for setting the node number. Allocated node
numbers: module 1 = 2 (default), module 2 = 3, module 3 = 4.
Maximum: 63
• One DIP switch for enabling/disabling digital input DI1 hardware
filtering. Default: filtering on
Connectors:
• Light transmitter and receiver (Hewlett-Packard Versatile Link) for
ACS 600 connection
• Two screw terminal blocks (Phoenix Contact MVBSTW 2,5/8-ST5,08) for digital I/O and power supply connections. Conductor crosssectional area: 0.5 to 2.5 mm2
Digital inputs 1 and 2:
• Voltage range: ±24 to 250 V d.c., 110 to 230 V a.c. ±10%
• Input current: 10 mA at 24 V d.c., 4 mA max. at 115/230 V a.c.
• Logical thresholds (d.c.): “1” > 12 V, “0” < 8 V
• Logical thresholds (a.c.): “1” > 40 V, “0” < 20 V
