DC6-40V 4-Channel 99 Steps Programmable Digital Time Relay Timer Controller Delay Module Solenoid Valve Control LCD Display

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.
Four-channel time relay, each channel has common, normally open and normally closed contacts, 4 sets of conversion.
99 groups of time(steps) for setting, adjustable timing range: 0.1 second to 9999 minutes(countdown).
4 channels in each step can be set in cycle or release state; the total number of Loops is adjustable from 0 to 9999(zero for the infinite loop).
Each step can be set in forward cycle to run for 0-999 times, supporting 20 layers of nesting loops.
Allowing external input of high level and low level signals to achieve trigger function and waiting input to run, jumping to another step ,stopping running functions.
User can set password to prevent others to change the setting parameters.
All setting parameters can be saved after power off.
