Galvanic isolation
Galvanic isolation between inputs and outputs as well as from
the supply voltage is provided.
Test voltages:
Between power supply and inputs/outputs: 2,3 kV AC, 1 min
Between inputs and outputs: 500 V AC; 1min
Max. permissible voltages:
Between inputs/outputs
against earth:
ß 33VAC
POWER SUPPLY
Depending on ordered version:
AC supply
Voltage: 90...260 V AC
Frequency: 48...62 Hz
Consumption: approx. 7 VA max.
Universal supply 24 V UC
AC supply: 18...30 V AC
Frequency: 48...62 Hz
DC supply: 18...31 V DC
Consumption: approx. 4 VA / 3W max.
* Instruments with optional system interface:
energization is via the bus connector from field bus coupler or
power supply module
Behaviour with power failure
Configuration and parameter settings:Permanent storage in EEPROM
BLUEPORT® FRONT INTERFACE
Connection to the controller front via a PC adapter (see ‘Additional
Accessories’). The BlueControl
®
software enables the KS 45 to be
configured, parameters set, and operated.
BUS INTERFACE (OPTIONAL)
RS 485
Connection via bus connector fitted in the top-hat rail. Screened
cables should be used.
