BUS Communication for Pneumatic actuators
|
| |
 El-O-Matic
bus-communication products provide the possibility to control pneumatic
actuators via various bus systems. Fieldbus interface cards are provided
as options in our LDN, HDN and FF34 products. They can be supplied in
water and dust proof versions as well as in explosion proof versions.
The LDN switchbox is available with ASI (actuator sensor interface),
the HD box with ASI, Profibus-DP or PA and the FF34 with Fieldbus
FoundationTM. All have basic functionality of two-way communication, the
fieldbus controller receiving input from the two position indicating
switches (mechanically adjustable 0-90º), and an output to the solenoid
valve(s) which may be to mono-stable or bi-stable. Bus wiring may be 2
wire or 4 wire depending on the system.
