326/327 Series - Time Delay Relay
SPDT - 3PDT, 10 Amp
E13224
The 326 on delay and 327 off delay are “octal” base constructed 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 precision RC (resistor – capacitor) network typically used in applications where
oscillators are not desired. Fixed time versions are available. Single pole and double pole
versions have 8 pin bases. The 3 pole version has 11 pins. All are intended for socket mounting.
