Switch Configuration | |||
Your choices are... | |||
Form A | Form A is SPST-NO. | ||
Form B | Form B is SPST-NC. | ||
Form C | Form C is SPDT-CO (change-over). | ||
Other | Other unlisted switch configurations. | ||
Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

Mounting | |||
Your choices are... | |||
Bracket (Flange) Mount | The relay is equipped with a flange. Typically, this flange is installed by bolting the unit to a matching flange that is welded to a corresponding wall. | ||
DIN Rail | The relay is equipped with a fastener that can attach to a DIN rail. | ||
Panel | The relay can be mounted in or on a panel. | ||
PC Board | The relay can be mounted on a printed circuit board (PCB). | ||
Socket or Plug-in Style | The relay can be mounted in a socket or on a printed circuit board (PCB). | ||
Other | Other unlisted mounting styles. | ||
Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

Input Voltage Type | |||
Your choices are... | |||
AC | The relay uses an AC voltage. | ||
DC | The relay uses a DC voltage. | ||
Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
![]() | |||
Number of Channels | The total number of relays in the module. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

Input 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. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Input Current Range | This is the range of input currents over which relays are designed to operate. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Output 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. | ||
Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
![]() | |||
Output 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. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Operating Temperature | This is the full-required range of ambient operating temperature. This represents the surrounding air temperature limits. | ||
Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
