(XPOW)
Relay outputs RO1...RO3
(XRO1...XRO3)
+24 V output
(XD24:2 and XD24:4)
Digital inputs DI1...DI6
(XDI:1...XDI:6)
Start interlock input DIIL
(XD24:1 [ZCU])
(XDI:7 [BCU])
Digital inputs/outputs DIO1 and DIO2
(XDIO:1 and XDIO:2)
Input/output mode selection by
parameters.
DIO1 can be configured as a frequency
input (0...16 kHz with hardware filtering
of 4 microseconds) for 24 V level square
wave signal (sinusoidal or other wave
form cannot be used). DIO2 can be
configured as a 24 V level square wave
frequency output. See the firmware
manual, parameter group 111.
Reference voltage for analog inputs
+VREF and -VREF
(XAI:1 and XAI:2)
Analog inputs AI1 and AI2
(XAI:4 ... XAI:7)
Current/voltage input mode selection by
jumpers (ZCU) or switches (BCU).
