| Using Alternating Relays with Different Voltages than Input Voltage |
| Issue |
| How do I use your Alternating Relays if the control voltage differs from the load voltage? |
| Solution/Resolution |
|
Normally, when using the same Control Voltage as load voltage, you would
add a jumper between pins 1 && 5 on SPDT units or pins 2, 6 & 10 on DPDT
units -- see Diagram below or the Instruction Sheet that comes with the unit
(click here
if you need a copy). The use of this jumper is to provide voltage to the
common connection of the output contacts.
If the Control Voltage differs from the load voltage, you do not need to add this jumper. Instead, you will supply the required load voltage from a separate source, connected to pin 1 on a SPDT unit and pins 2 & 10 on a DPDT unit. In addition, you will not have a connection from the load(s) back to L2 of your Control Voltage.
Please note: the above discussion applies only to our SPDT (ARPxxxA6 & ARPxxxA6R) and DPDT (ARPxxxA2 & ARPxxxA2R) units, where xxx is the input voltage, i.e., 024, 120, etc. It does not apply to any of our cross-wired units (ARPxxxA3, ARPxxxA3R, ARPxxxA8 or ARPxxxA8R) units. For these products, the input voltage & operating voltage for the output loads must be the same. |
