FAQ (Text Format)

1. What PLC systems are compatible with the ABE7H16R20?
It works with Modicon Quantum, Modicon Premium, X80 modules, and TM3 expansion units.

2. Can this module switch inductive loads?
Yes, because each output uses an electromechanical relay capable of handling typical industrial inductive devices.

3. Does the module include built-in protection?
Yes, every channel includes a fast-acting 2 A fuse that helps protect both wiring and connected equipment.

4. How does this sub-base simplify maintenance?
Its modular layout allows technicians to replace components without removing field wiring, which significantly reduces downtime.

5. Is LED indication available for each relay?
Only a power-on LED is included; output status depends on the PLC’s relay activation state.
