NOTE
1) Limitations on loop inductance
For loop inductances outside the recommended range, only one frequency level may be available.
For very small loop inductances, the maximum loop resistances are lower.
2) Current load of the relay contacts
The rigid gold plating on the relay contacts will be destroyed if the switching current exceeds 100
mA. Relays with contacts that are prestressed in this manner can only reliably switch currents over
100 mA!
3) Terminal block data
Grid dimension 5.0 mm, conductor cross-section 0.25 - 2.5 mm², AWG 24-12
