Product Description
2.1
Function
General
This signal conditioner provides the galvanic isolation between field circuits
and control circuits.
The energized to safe (ETS) function is permitted for SIL 3 applications.
An internal fault or a line fault is signalized by the impedance change of the relay contact input
and an additional relay contact output.
A fault is signalized by LEDs and a separate collective error message output.
KFD2-RSH-1.2E.L2(-Y1)
The device is a relay module that is suitable for safely switching applications of a load circuit.
The device isolates load circuits up to 60 V DC and the 24 V DC control circuit.
KFD2-RSH-1.2E.L3(-Y1)
The device is a relay module that is suitable for safely switching applications of a load circuit.
The device isolates load circuits up to 230 V AC and the 24 V DC control circuit.
Y1 Version
This device is compatible to the following control: Emerson DeltaV CHARM.
Compatibility check to other ESD/DCS systems on request.
2.2
Interfaces
