Description
The DCF126 is an eight-channel, 24 VDC discrete-input termination and wire-break detection board for ALSPA P320 TGC installations, used with IC693MDL645 and IC693MDL655 input modules. It supplies each field sensor, filters and transfers the eight logic-input signals to the PLC module, and provides a dedicated wire-break diagnostic output for each channel.
The board operates from 19 to 30 VDC, with a nominal supply of 24 VDC and a maximum current consumption of 600 mA. It is DIN-rail mounted and grounded through the rail, is specified for operation from 0 to 60°C, and provides a green H1 indicator for 24 VDC supply presence. Its logic interface supports both standard and redundant loading arrangements.
Please check compatibility with the installed hardware and system configuration before ordering.
