The safety relay wiring diagram is shown below. Now we will see how to connect a safety relay with the dual channel emergency. To power ON the safety relay, we need to provide 24V DC at the a1 terminal & the a2 terminal is connected to GND. After that, we need to connect both sets...
safety relays, by using suitable wiring it is also possible to select: Simultaneity monitoring to monitor safety components over time Relay start using a monitored start button Short circuit monitoring to detect short circuits between the connection cables and to shut down the outputs or prevent ...

Relay outputs The outputs are electrically decoupled and of redundant design Connection options By using suitable wiring the following functions can be selected: Relay start with automatic start or a start button Monitoring of downstream relays or contactors On the series ESM-BA.. safety relays, by...
Check the external wiring and restart the safety relay. If the fault is still present, contact Carlo Gavazzi. 7. FAULT DIAGNOSIS Fig. 4 - Change of NE1/4-D safety relay 7 8. APPLICATION EXAMPLES Example 1. Dual channel contact extension (Fig. 3) Closing the NO input contacts, the unit...

Check CH1 and CH2.green/blue/green CH1 and CH2 closed, the safety relay wait for reset.Check reset settings, wiring and reset circuit.red/flash fast red/red The safety relay is in failsafe mode.Do a power cycling.Technical data Measurements Height/width/depth 120 mm/22.5 mm/120 mm Power...
The function saves the use of external components such as speed monitors and the associated wiring. The release of a danger zone while the machine is moving away from the operator increases productivity. Without the SDI function, the machine must be safely stopped during material loading and remov...
Wiring can be complex on big systems. Simple Difficult to commission and fault find when the system is down. No software programming required Complete rewiring is required if changes need to be made later. Option 2: Configurable safety relays ...
