IPA T RLY4 • Setup Guide (Continued)
ATTENTION:
• Connect +12 VDC to the C pin only and connect the return to one or all of the Input pins (1 through 4) for the relays that
you will use. Reversing the connections can damage the power supply.
• Raccordez une source +12Vcc uniquement à la broche C du connecteur et raccordez le circuit de retour à une ou
plusieurs broches d'entrée (1 à 4) pour les relais utilisés. Inverser les raccordements pourrait endommager la source
d'alimentation.
• Observe proper polarity when making connections to the Power port on the MLC 104 IP Plus controller. Miswiring can
damage the port.
• Veillez à respecter la polarité appropriée lorsque vous effectuez des raccordements au port d'alimentation du
contrôleur MLC 104 IP Plus. Une erreur de raccordement pourrait endommager le port.
NOTES:
• Connect the I/O control line to the Input 1 terminal for relay 1, Input 2 for relay 2, and so on.
• Figure 3 is a wiring diagram of a typical application: an Extron MLC 104 IP Plus controlling an IPA T RLY4 relay function
(see the MLC 104 Plus Series User Guide for information on configuring the MLC to control the IPA T RLY4).
• Figure 4 shows an application that includes an external power supply and an Extron IPCP Pro Dual-NIC Controller.
When the relay accessory is connected to an IO port of an IPCP Pro module, ground the external power supply to the
IO port ground pin on the control processor.
