FMX Duplexor and Triplexor Alternating Relays

Duplexor and Triplexor Alternating Relays are designed to fit 8-pin octal sockets and feature an operating temperature of -18° to 149°F.

• Duplexor
  - Optional low-profile selector switch allows unit to alternate 2 loads as normal or lock the relay into one or the other
  - Control duplex loads
  - SPDT or DPDT
  - 10A contact rating
• Triplexor
  - Top-mounted switch allows use as standard Triplexor or Duplexor until system expansion required additional third load
  - Control triplex loads
  - SPNO
  - 3A contact rating

Star-Delta Motor Start Timer

A Star Delta timer holds the star wiring of a motor for a set time before switching to delta wiring. These timers feature two timer ranges as a result of this design.

• Universal voltage
• Two Timing Ranges:
- Star: 0.1 to 1 second
- Star to Delta: 0.1 to 1 second
• DIN rail mountable
• 16A contact rating

Elko Asymmetric Cycle Timers

Asymmetric Cycle Timers feature independent ON Delay and OFF Delay time settings. Both DIN rail mountable and octal base models are available.

• Independent ON Delay and OFF Delay time settings
• Timing Range: 0.1s to 100 days
• 8A or 16A contact rating depending on chosen model
• External pots included with select models

Timer/Counter/Tachometer

Timer/Counter/Tachometer devices are multi-function components. They feature 3 operation modes, two output configurations, and a digital display.
