This controller is a 4-channel time relay; each channel of relay can run independently and it also can run in turn. It can be controlled by detecting four channels of input voltage signal to control four loads on/off independently or in turn, such as controlling four solenoid valves to work independently or work in turn, controlling four input signal to delay on/off, etc.

Features:
Industrial LCD display, 4 keys for easy operation, with reset function.
High performance microcontroller for high stability, high reliability and low power consumption.
Reverse power protection function, avoiding surge current shock.
Each group of relay has common, normally open and normally closed contacts, 4 sets of conversion.
Four-channel time relay, adjustable timing range: 0.1 second to 9999 minutes(countdown), the total number of Loops is adjustable from 0 to 9999(zero for the infinite loop).
Effective signal input types of 4 channels can be set to high level and low level, rising edge and falling edge, etc. and can connect with external switch, PNP sensor and NPN sensor. The high level signal threshold value is adjustable from 0.1V to 40.0V.
Four channels of effective signal can be set to control four channels of time relay trigger to run, high level to maintain running, trigger reset and restart etc.
User can set password to prevent others to change the setting parameters.
All setting parameters can be saved after power off.

Specifications:
Timing Range: 0.1s - 9999min Adjustable
Cycle: 0 - 9999 times Adjustable
Working Power Supply: DC6-40V  
Four Signal Input Impedance > 100K
Input Signal Voltage Range: DC0-40V
Working Current: When backlight off current is about 9mA/12V(0.11W)

Q

Is it possible to run one timer as loop, and the other three as one shots, triggered by the first?

A
  • I am not sure what you are trying to do but I did find a manual at http://www.knacro.com/knacro-ptr4-sp-controller-4-way-programmable-time-relay-dc-6-40v-99-groups-time/ it is lacking some details but the best that I could find and it might offer what you are looking for. It is a nice timer after you figure it out.

    I bought this to run 4 perastaltic pumps to automatically measure my nutrients for me in a hydroponic system. The ratios of my nutrients all have a common denominator of 15 seconds of run time. I just set the total number of loops on each channel based on the ratios needed. No more graduated cylinders required, just push the start button and walk away. I have not figured out how to make the inputs work yet. I can't find a manual for this thing so I kind of have to guess how things work so it lost a star. If you try to look it up this is the ptr4-ind not the ptr4-sp. I don't know why it is so hard for vendors to include a link to the manual in the description. Who knows, maybe someday people that sell electronic devices will realize we live in the information age. The manufacturer could even reference a web address on the part itself. Probably makes too much sense
