FAQ

Question?

What PLCs is the ABE7-H16R21 compatible with?

Answer:
It is designed for the Modicon M340 and Twido PLC series, connecting to their digital I/O modules via a 20-way HE10 connector cable.

Question?

What is the maximum switching current per relay channel?

Answer:
Each relay channel has a maximum switching current that depends on the load type. The label indicates different ratings, but for common use cases, you should always refer to the official datasheet for specific load curves (e.g., resistive vs. inductive loads).

Question?

Does this sub-base require an external power supply?

Answer:
Yes, the ABE7-H16R21 requires a 24V DC supply to power the relay coils. This is separate from the signal voltage being switched by the relay contacts.
