The TDR series of electronic relays is a processor based control that can have many different functions. The operation of the TDR is determined at the time of manufacture, based on the firmware loaded into the relay.


Special functions (X) that are unique to a customer’s specific application are available by contacting the factory.


Functions available include:

C - On Delay (Delays to turn On)

D - Interval On (Turns On and then times out)

F - Off Delay (Turns on then delay turning Off after loss of signal)

L - Pulse Frequency (Supplies prox power on monitors pulse frequency)

R - Repeat Cycle (On & Off & On & Off etc.)

S - One Shot (One output per input)

U - Universal (Multiple functions and time ranges)

Mounting: Plug-In

Termination: 8 or 11Pin

Packaging: Dust Cover

Weight: 8.5 Oz. Approx.


Ambient Temperatures

Operating: 0°C to 65°C

Storage: -40°C to 85°C



On MRS with remote timing resistors, multiples of 2.7 megohms will increase the time delay by 1 minute ±20%.


For adjustment codes 4 a jumper or resistor must be installed across terminals 5 and 6 for the On Time and Terminals 7 & 8 for the Off Time to allow the timer to time out.
