236TD /237 Series - Time Delay Relay
DPDT, 10 Amp
E13224
Rugged, industrial time delay versions of the popular 219 series. On delay, off delay and interval
timing is available. Contacts can be configured up to four pole double throw or six pole single
throw. Blow out magnets can be added to increase DC switching capability. Time ranges are
adjustable over a 1:100 range. Locking shaft potentiometer and integral hold down clip are
standard. A large option list makes this product easily customized for special applications.
**Nuclear versions available**
