5.6 General technical data
Product property EJx9xx
Supply voltage (SELV / PELV) 24 V
DC
(–15% / +20%)
Permissible ambient temperature (operation) -25°C to +55°C
Permissible ambient temperature (transport/
storage) -40°C to +70°C
Permissible air humidity 5% to 95%, non-condensing
Permissible air pressure (operation/storage/
transport) 750 hPa to 1100 hPa
(this corresponds to an altitude of approx. -690 m to
2450 m above sea level, assuming an international
standard atmosphere)
Minimum/maximum cycle time approx. 500 µs / according to project size (if a user-
specific project is used)
Fault response time ≤ watchdog times
Watchdog time min. 2 ms, max. 60,000 ms
Cable length between sensor/actuator and terminal unshielded max. 100 m (0.75 or 1 mm²)
shielded max. 100 m (0.75 or 1 mm²)
Input process image dynamic in accordance with the configuration
Output process image dynamic in accordance with the configuration
Reaction time (read input/write to E-bus) typically: 4 ms,
maximally: see error reaction time
Output current of the clock outputs typically 8 mA, max. 11 mA
Output current of the outputs max. 500 mA
Actuators • inductive
• resistive
• capacitive
When selecting actuators please ensure that the test
pulses do not lead to actuator switching
Actuator switching frequency (inductive load) max. 2.5 mH at 100 Hz
max. 1 H at 1 Hz
These are example working points. The user must
evaluate the actuators used in relation to energy.
