6. Configure output addressing in Unity Pro or Concept programming software (requires 2 output words).

FAQ

Q: Is 140DDO15310 source or sink type?
A: Sink type (negative logic). The module sinks current from the load to ground. For source type (positive logic), use 140DDO35301.

Q: What is the difference between 140DDO15310 and 140DDO35310?
A: 140DDO15310 is 5 VDC TTL output. 140DDO35310 is 24 VDC negative logic (sink) output. Both are 32-point modules but with different voltage ratings.

Q: What is the difference between 140DDO15310 and 140DDO35300?
A: 140DDO35300 is a 32-point solid-state output module with different voltage/current specifications. 140DDO15310 is specifically designed for 5 VDC TTL applications.

Q: Can I use 140DDO15310 with 24 VDC loads?
A: No. This module outputs 5 VDC TTL only. For 24 VDC loads, use 140DDO35310 (sink) or 140DDO35301 (source).

Q: What is CableFast compatibility?
A: CableFast is Schneider Electric's quick-connect terminal block system that plugs directly into the SUB-D connector, eliminating individual wire termination and reducing installation time.

Q: Is 140DDO15310 compatible with M580?
A: No. 140DDO15310 is designed for Modicon Quantum racks. M580 uses different I/O module architecture (e.g., BMXDDO series).

Selection Tips

• Quantum, 32-point, 5VDC TTL, sink: 140DDO15310
• Quantum, 32-point, 24VDC, sink: 140DDO35310
• Quantum, 32-point, 24VDC, source: 140DDO35301
• Quantum, 32-point, solid-state: 140DDO35300
• Always verify: Load voltage (5V TTL vs 24VDC), logic type (source vs sink), and current requirements before ordering
• Order compatible connector: CableFast terminal block or SUB-D 50-pin cable assembly
