67TD Series
Miniature Time Delay Relays  


​When small size is a requirement 67 series relays fit where others won’t. The miniature ice cube timers are capable of handling up to 5 amps. Typical configuration is DPDT on delay. Four pole versions are available. Time adjustments are through a recessed potentiometer. No exposed adjustment knob to bump.

236TD /237 Series
Time Delay Relays

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.

286/287 Series
Squre Base Time Delay Relays  

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 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.

326/327 Series
Time Delay Relays  

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.

388 Series
Time Delay Relays  

The 388 timers are square base, bladed versions of time delay relays. On delay, off delay and interval functions are all available with either AC or DC inputs. On delay and interval products can have up to three poles. Off delays have two poles. The timing circuit is oscillator based. Fixed time and externally adjustable versions. Both socket and flange mount versions are available.

388 Series
True Off Timer Relays  

The 388 true off timers are square base, bladed products. Solid state circuitry combined with a magnetic latching relay allow this product to time when no power is applied. Contacts transfer when power is applied. Timing begins when power is removed. Contacts return to the home position at the end of the timing cycle. No external control switch is needed to initiate timing. The package on this series is typically socket mounted.

235 Series
Adjustable Current Sensors  

The 235 series current sensor combines solid state circuitry with a SPDT, 10 relay. Knob adjustable user settings detect AC current levels generally ranging from 1.5 to 15 amps. Quick connect terminals are standard with socket or side mounting. Custom ranges and voltages are available.

236 Series
Adjustable Voltage Sensors  

The 236 series voltage sensor combines solid state sensing circuitry with a SPDT 13 amp relay or a DPDT 10 amp relay. The single pole version has recessed potentiometers for adjustment.The double pole version has knob adjustments. Pull-in voltage is 75 to 115% of nominal voltage. Dropout is 75 to 95% of set pick up.
Applications: Brownout protection, warning of under voltage condidtions and over voltage protection.

349 Series
Over/Under Voltage Sensor Relays

Under / Over voltage sensing relay incorporating 219 series internal components coupled with an electronic module. Pull-in voltage is adjustable from 85 to 135VAC for frequencies ranging from 50 to 400 hertz. Hysteresis is typically set for a 4 volt differential but can be user adjustable from 3 to 14 volts when external connections are available.
