DIO-400
Universal Digital In, 24 or 48 VDC Digital Out
The DIO-400 block interfaces digital input and output signals
used to read on or off device states and to switch DC voltages.
It supports 16 isolated input channels and eight isolated out-
put channels. Input channels are individually hardware config-
urable for input voltage range. Open-collector output channels
can switch voltages of 24 or 48 VDC with a maximum load cur-
rent of 250 milliamperes. The DIO block can cable connect to
an RLY-100 or RLY-200 auxiliary relay block to provide relay
outputs. The block supports redundant I/O electronics.
