DSDO115A 3BSE018298R1

16 independent relay passive contact outputs
Divided into 4 groups x 4 channels, each channel has independent mechanical relay dry contacts without polarity restrictions; It can drive solenoid valves, indicator lights, on-site relays, valve switch circuits, and contacts can be externally connected to AC/DC loads.
Group isolation, single path faults do not affect each other
Electrical isolation between channels, single channel load short circuit and overcurrent only damage the corresponding circuit relay, without causing the entire card to fail, ensuring the normal operation of other interlocking outputs.
Contact capacity adapted to conventional on-site loads
Single relay supports conventional industrial loads, suitable for power plants, chemical switch valves, sound and light alarms, and motor auxiliary circuit control; The software can set two modes: pulse output and hold output.
Channel level status and fault diagnosis
Each channel is equipped with running LED indicator lights; Real time detection of output circuit short circuits, overloads, and relay faults, uploading fault codes to the AC410/AC450 main control, and quickly locating abnormal points in the control room.
Real time communication and interaction of MXB backplane
Relying on the DSBB110A/DSBB175 MXB backplane bus and bidirectional transmission of output instructions to the controller, independent hardware processing of output logic, without occupying CPU control scanning cycles.
