Wiring Diagrams and Functions

3 Wiring Diagram and Functions (83.11-83.21)

3a: Start via contact in supply line (A1)

83.11: Al On-delay
83.21: DI Interval

4 Wiring Diagram and Function (83.41)

Start via contact into control terminal (B1)

BE: Off-delay with control signal

4a: Possible to control an external load, such as another relay coil or timer, connected to the signal start terminal B1.

4b: With DC supply, positive polarity must be connected to B1 terminal (according to EN 60204-1).

4c: A voltage other than the supply voltage can be applied to the command Start (B1), for example:

A1-A2 = 230 V AC
B1-A2 = 24 V DC

Other Data (83.41)

Minimum control impulse: 50 ms
Recovery time: 200 ms
Mounting: 35 mm rail mount (EN 60715)

Working Conditions

In conformity with the European Directive on EMC 2014/30/EU, the timer relay offers a high level of immunity against radiated and conducted disturbances, exceeding the requirements of EN 61812-1. However, external factors like transformers, motors, contactors, switches, and power cables can cause disturbances. To mitigate this, wiring cables should be kept as short as possible. If necessary, protect the timer with relevant RC networks, varistors, or surge voltage protectors.
