4 Electrical Interfaces
Connector X2 for digital signal interface
Cable break monitoring
Inputs CLK and DATA of the digital signal interfaces are monitored for cable
break – irrespective of which transducer type is connected.
The status of cable break monitoring can be read out via field bus. The reaction
to a cable break is configurable.
Cable break monitoring
Detailed information can be found in the "Firmware" User Manual.
Power supply to the transducer
Power is supplied to the transducer via pin 7 on connector X2.

Power supply to
the transducer
There is joint fusing of this power supply for X2, X5, X6 and X7. The total
supply current must therefore not exceed the following value:
Imax (X2+X5+X6+X7) = 300 mA
The 24 V or 5 V supply voltage is configurable (see "Firmware" User Manual).
An external power supply to the transducer is also possible. However, the 0 V
transducer supply must be connected to supply zero.
The supply voltage is cut off in the event of a possible short circuit in the supply
voltage to the transducer. A fault reaction can be configured (see "Firmware"
User Manual). The voltage is available again as soon as the short circuit has
been eliminated.
4.2.3 LocalCAN
The local CAN interface enables transducers, actuators and further
valves/pumps to be networked. The interface is not electrically isolated; short
cables and equipotential bonding must therefore be provided.
EMC protection requirements
Immunity to interference as per DIN EN 61000-6-2
(evaluation criterion A)
Emitted interference as per DIN EN 61000-6-4
Physical
ISO/DIS 11898 CAN-HIGH SPEED
Maximum voltage capacity
±40 V long-term (between CAN_H and CAN_L)
±2.5 kV ESD (classification A: Human Body Model,
C = 100 pF, R = 1.5 kΩ)
Maximum permissible number
of CAN bus nodes
32 or 110

nodes", page 67
Technical data for the
LocalCAN interface

To connect the valves/pumps to a CAN network, we recommend molded cord
sets with an integral straight mating connector.
