Macromatic's TR-6 Series Time Delay Relays Redesign

Wednesday: February 22, 2017 : Time Delay Relays


The Macromatic TR-6 Series Time Ranger programmable time delay relays have gone through an extensive redesign that was introduced in February 2017.  While many features & benefits were retained, there were several major improvements summarized below:

Changes Old TR-6 Design New TR-6 Design
Input Voltage Individual Voltages, i.e., 24V AC/DC, 120V AC/DC, etc. Universal Input Voltage of 24-240V AC & 12-125V DC
Programmable Time Ranges 16 Ranges Covering 0.1 Second - 2 Hours (0.6 Seconds - 24 Hours on Dual Time Functions) 16 Ranges Covering 0.05 Seconds - 100 Hours
Multi-Function Versions Offered No Yes

These improvements all add up to one important benefit: the number of catalog numbers required in your stock to cover a variety of applications has been reduced dramatically.  Need products for 12V, 24V, 120V and 240V applications—covered with one unit.  Have some applications requiring a 10 second delay or 5 minute delay or 48 hour delay—covered with one unit.  Want to meet multiple function requirements like On Delay or Off Delay or Retriggerable Single Shot with one unit—covered with multi-function versions.

There is one other important change that could impact the application of these products in very rare situations where multiple time delay relays are all initiated by the same trigger switch.  The new TR-6 Series with functions triggered by a control switch (Off Delay, Single Shot, Watchdog, etc.) now have a line voltage trigger vs. the older designs that had a 10V DC trigger circuit.  A line voltage trigger is where the voltage across the control switch terminals is equal to the input voltage of the unit.  Problems may occur when multiple units with different trigger voltages share a common control switch.

At the same time these improvements were made, the TR-6 Series retained the same rotary switch to easily select one of the 16 built-in time delay ranges and the same potentiometer knob to adjust within that range.  The new multi-function products use the same style rotary switch, but with 8 positions to select one of the built-in functions.  The time delay functions operate the same.  And the pin configurations for both 8 & 11 pin products have not changed. All this makes these new versions drop-in replacements for the older products.
