Relay Switches & Timer Relays

Alternating Relays

Alternating relays are used in special applications where the optimization of load usage is required by equalizing the run time of two loads.

• For duplex loads
• 120VAC Control voltage
• AR-TL Series Relays:
  10A SPDT output configuration
  can be used with one or two control switches
• ARX-TL Series Relays:
  10A DPDT cross-wired output configuration
  can be used with two or three control switches

Pump Seal Failure Relays

PSFR relays are designed to monitor the shaft seals of submersible pumps. The relay output can be used to give an alarm indication of a leaking seal. The relay will automatically reset when the fault condition clears.

• Monitors submersible pump seals for leakage
• 8-pin, SPDT, single channel for one pump
• Adjustable sensitivity ranges (4.7K to 100K ohm)
• Uses industry-standard 8-pin octal sockets

Intrinsically Safe Relays

The ISD Series of Intrinsically Safe Relays provide a safe and reliable method to control up to four loads (motor starters, relays, etc.) with up to four input devices (switches, sensors, etc.) located in a hazardous area.

The ISE Series of Intrinsically Safe Relays provide a safe and reliable method to control a single load (motor starters, relays, etc.) with a single input device switches, sensors, etc.) located in a hazardous area.

Timer Relays

Timer relays provide simple time-based control, with multiple modes and adjustable timing ranges, discrete outputs, and a mechanical or electronic display. A variety of timers are available from well-known industry brands, such as Fuji, Dold, Murrelektronik, Koyo and AutomationDirect's own ProSense line.

Multi-Function Digital Counters, Timers and Tachometers

Multi-function digital counters provide functions such as counter, timer, combination timer-counter or tachometer. Their LCD displays show present values, setting values and menu parameters for easy setup.

Relay and Timer Sockets

Relay sockets provide a quick and easy way to mount and wire relays on 35mm DIN rail or on a panel.

Relay and Timer Accessories

Relay accessories include thermal pads, MOV and diode plug-in modules, bus bars, separator plates, relay jumpers and more.
