Emerson KC3040X1-BA1 PLC5 120 VAC DI Signal Conditioner Card
A DeltaV signal conditioner for the documented PLC5 120 VAC or 125 VDC discrete-input path.
Product Profile
PROFILEEmerson KC3040X1-BA1 is a PLC5 120 VAC discrete-input signal conditioner card for the documented legacy PLC5/1771 interface path.
The published signal power values are 120 VAC at 50/60 Hz and 10 mA per channel, or 125 VDC at 3 mA per channel. This is a different electrical execution from the 24 VDC BB1 variant.
Emerson specifies connection only to KC3021X1-BA2. The card cannot be removed or inserted with system power energized and contains no user-serviceable parts.
