4-channel extension module
The EM top2 module upgrades the 365-day time switch TR 641
top2 RC, TR642 top2 and TR 644 top2 to 4 channels (C5-C8).
The module is linked to the 365-day time switch via a DATA
interface. Corresponds to type 1 B in accordance with IEC/EN
• The EM top2 module is designed for installation on DIN top
hat rails (in accordance with EN 60715).
• Strong interference fields can have an effect on the clock.
Do not install module near inductive consumers.
Lay separate cable for power supply.
Shield inductive consumer.
