Input (Pick-up) Voltage Range
|
|
This is the range of voltages that, when applied across the input terminals, maintain an "on" condition across the output terminal. This parameter is also used to define the absolute limits of input voltage that relays can withstand without damage. Input voltage range is known as must-operate, pick-up, or turn-on voltage.

|
| |
Dropout Voltage
|
|
The dropout voltage is the voltage applied to the input at or below which the output is guaranteed to be in the off state. Dropout voltage is also known as the must-release or turn-off voltage. It is considered to be the "noise immunity" level of the relay.

Maximum Current
|
|
This is the maximum continuous current allowable across the relay output terminals under the specified heat dissipation and ambient temperature conditions. Generally, AC current is specified in RMS units. Maximum current is also known as the maximum switching voltage range, or the maximum switching current.

Load Voltage
|
|
This is the output supply voltage range in which the relay normally operates. Generally, AC voltage is specified in RMS units. Load voltage is also known as the maximum switching voltage range, and/or as line voltage.

Turn-on Switching
|
|
|
| |
Your choices are...
|
|
|
| |
Instant ON
|
|
Devices immediately turn-on the load when the pickup voltage is present. Instant-on is used to control inductive loads.
|
| |
Peak Switching
|
|
Peak switching turns-on the load when the control voltage is present and the voltage is at the peak. It is used to control heavy-duty inductive loads.
|
| |
Random Turn-on
|
|
Random turn-on is important particularly for inductive loads (transformers, etc.).
|
| |
Zero Switching
|
|
Devices switch at the point where the AC load voltage or current passes through zero as it changes polarity. Zero switching is used to control resistive loads.
|
| |
Other
|
|
Other unlisted or proprietary turn-on switching methods.
