DC6-40V 4-Channel Programmable Digital Time Relay Timer

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.
