Function
KCD2-STC-1(.SP)
This signal conditioner provides the galvanic isolation between field circuits and control
circuits.
The device supplies 2-wire transmitters in the field, and can also be used with current sources.
The device transfers the analog input signal to the control side as an isolated current value.
Bi-directional communication is supported for SMART transmitters that use current modulation
to transmit data and voltage modulation to receive data. If the HART communication resistance
in the loop is too low, the internal resistance can be used.
Test sockets for the connection of HART communicators are integrated into the terminals
of the device.
The output is selected as a current source, current sink, or voltage source via DIP switches.
The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
SP version
The devices are available with screw terminals or spring terminals. The type code
of the versions of the devices with spring terminals has the extension ".SP".
KCD2-STC-Ex1(.SP)
This isolated barrier is used for intrinsic safety applications.
The device supplies 2-wire transmitters in the hazardous area, and can also be used
with current sources.
The device transfers the analog input signal to the non-hazardous area as an isolated current
value.
