Control Relays / Timers



Industrial Control Relays
General purpose industrial control relays are available in ice cube, card relay, and solid state relay styles for use in a wide range of applications. A variety of accessories are also available, including relay sockets, relay removers, protective covers, spare card relays, and metal oxide varisters (MOV) and diode circuits offered as convenient plug-in modules.

Timers / Timer Relays
AutomationDirect offers solid state timers and digital timers from two leaders in the industry, FUJI Electric and Koyo. All timer relays meet UL and CE conformity. Koyo has been selling timer relays for over 30 years. FUJI Electric has been in business since 1923 and has been selling timer switches in the U.S. since 1970. All FUJI products are produced under ISO9001 and ISO14000 criteria.

Motor Control Relays ...New
Phase monitor relays provide protection against premature equipment failure caused by voltage faults on 3-Phase systems. Alternating relays are used in special applications where the optimization of load usage is required by equalizing the run time of two loads. Pump failure relays are designed to monitor the shaft seals of submersible pumps.

Solid State RelaysSolid State Relays
A solid state relay switch is a control relay with isolated input and output, whose functions are achieved by means of electronic components without the use of moving parts such as those found in electromechanical relays. These electronic relays are ideal for applications with many contact closures since solid state relay switches offer a greatly extended life compared to electromechanical relays.

Motor Control RelaysMotor Control Relays
Phase monitor relays provide protection against premature equipment failure caused by voltage faults on 3-Phase systems. All ProSense 3 phase monitor relays are designed to be compatible with typical Wye or Delta systems. Phase monitoring relays protect against single phasing regardless of any regenerative voltages.

Alternating relays are used for motor load control in special applications where the optimization of load usage is required by equalizing the run time of two loads. The alternating action is initiated by a control switch, such as a float switch, manual switch, timing delay, pressure switch, or other isolated contact. Each time the initiating switch is opened, the output relay contacts will change state, thus alternating the two loads.

Pump failure relays
are designed to monitor the shaft seals of submersible pumps. A resistive-measuring probe provided by the pump manufacturer is installed in the pump seal cavity. If the pump seal starts to leak, contaminating fluid enters the seal cavity, lowering the resistance between the internal probe and the common connection. When the resistance drops below the user-adjustable sensitivity setpoint of the relay, the output relay energizes.

Koyo Timer RelaysKoyo Timer Relays
1/16 DIN Digital Timers (KT Series) - offer flexible features at a great price. A large, easy to read display is offered in a small 1/16 DIN size. Large, bright red timer LED display has a 12 mm character display height which allows it to be seen easily from a distance and at an angle. In addition, set values use a green LED display to differentiate from timing values.

Fuji Timer RelaysFuji Timer Relays
Fuji Timer Relays (MS Series) - The MS4S series super timers are 1/16 DIN style timer relays designed for process control, machine tool control, safety control and many other types of applications. The timer switches are plug-in 8-pin or 11-pin surface/ DIN rail mountable with up to four selectable modes of operation and four selectable timing ranges.

Fuji Miniature Timer Relays (ST7 Series) - The ST7 series timer switches are very compact and highly accurate. They offer a time delay operation type with a single timing range. These timer switches are designed to optimize mounting space in small areas. These super timers are highly accurate, with a repeat accuracy within ±1% at maximum setting time. Mounting is by DIN rail or by securing directly to a panel with a fastener.
