5Vdc PLC Relay Base Terminal Block and Plug in Relays
These 5Vdc PLC relay base terminal blocks are designed for SPDT relays. Bases are available in screw or spring style terminations. The bases are available in three styles:
- Universal: Can wire sensors or actuators.
- Input: Designed specifically to wire sensors without the need for additional terminal blocks.
- Output: Designed specifically to wire actuator without the need for additional terminal blocks.
Note: The pluggable relays and bases must be ordered separately.
(Plug in Relay + Base Terminal = Combination Part Number)
