Main functions
Dry contact isolation relay output, completely isolating relay contacts from PLC logic circuits; Each contact point is independent of each other.
Can connect to AC or DC loads without the need for a unified public power supply; Each circuit can use different voltage levels.
Suitable for driving contactors, solenoid valves, alarm circuits, and external door interlock circuits.
Receive BIU/IC670CPU350 output instructions, controlled by the upper level 90-30/90-70/RX3i through the Genius bus.
Typical Engineering Application Cases
Case 1: Genius Remote I/O Station for Power Plant Auxiliary Control
Remote on-site, different voltage level circuits need to be output: some 120VAC, some 24VDC; Using MDL930, each point is independently isolated without considering common ground interference, driving external contactors and alarm circuits.
Case 2: Metallurgical and water treatment interlocking output
The voltage of the on-site execution circuit is not uniform, and we do not want to do a lot of signal isolation. We directly use MDL930 dry contacts for isolation output; Relay contacts are used as interlocking hard contacts for output.
Case 3: IC670CPU 350 Local Intelligent Station
The local logic directly drives the external isolation interlock circuit, without relying on the upper PLC.
