C I/O Boards I2C AIO:8 analog inputs, 8 analog outputs, 2 digital inputs
I2C DIO: 6 digital inputs, 8 digital outputs
I2C ADIO:4 analog inputs, 4 analog outputs, 4 digital inputs, and 4
digital outputs
Note: The Maxum II Airbath/Airless configuration is also compatible
with original version CAN bus I/O from Siemens. CAN I/O boards
have lower I/O channel count and capacity; consult factory for detail
as needed.
Digital Inputs Optically coupled with a common for all inputs. Self powered floating
contact input, or configurable for sinking or sourcing current. Sourcing
current mode: 24V internal isolated supply, with positive terminal of
supply at common. Sinking current mode: 5V internal isolated supply,
with negative terminal of supply at common.
Digital Outputs Floating double-throw contacts, maximum contact load rating 1 A at
30 V (AC or DC). External diode shunt suppression should be used
for inductive DC loads, preferably at the load
Analog Inputs Each input configurable for current or voltage; -20 to +20 mA into 50
ohms or -10 to +10 V with 100K. ohm input resistance, fully
differential. Each differential channel operates within the range of -
100 to +100V common mode to chassis ground.
Analog Outputs 0/4 to 20 mA into 750 ohms maximum, common negative pole,
galvanically separated from ground, freely connectable to ground
Termination Terminal strip for braided or solid cable with maximum section of 18
AWG or 0.82 mm
