286/287 Series - Squre Base Time Delay Relay
SPDT - 3PDT, 10 Amp
The 286 on delay and 287 off delay are square base, bladed versions of time delay relays. Both AC and
DC versions are available. On delays can have up to three poles. The timing circuit is a fully encapsulated
E13324 precision RC (resistor – capacitor) network typically used in applications where oscillators are not desired.
Fixed time and externally adjustable versions are available. The package on this series is typically socket
mounted. It can also be panel mounted allowing direct connections to terminals with quick-connects or
soldering.
