NOYITO 4-Channel Programmable Time Relay Controller 99-Step Multi-Channel Timing Trigger Solenoid Valve Linkage Control LCD Display Optocoupler Isolation

NOYITO 4-Channel Programmable Time Relay Controller 99-Step Multi-Channel Timing Trigger Solenoid Valve Linkage Control LCD Display Optocoupler Isolation

• The PTR4-SP controller can be set 99 groups time (steps), each step the relay switch state can be set switch “ON/OFF” (close or open) , use external input voltage signal or switch it can achieve many functions. The controller can be used to control four solenoid valve - linkage, sequence control as PLC, etc.
• Industrial LCD displays, set by buttons, easy to use, has reset function. High-performance microcontrollers, industrial-grade reliability, high process stability, low power, reverse power protection function, avoiding surge current shock.
• Four relays, each group of relays has common and normally opened, normally closed contacts, 4 sets of conversion; 99 groups time, each timer range: 0.1 seconds ~ 9999 minutes adjustable, the total number of Loops is adjustable from 0 to 9999 ( “0” means run loops all the time ) ;
• Each step can be set to cyclic jump to run forward 0-999 times, 20 layer nesting loops support ; The external input high level and low level signals, achieve trigger function, wait input to run, jump to another step ,stop running functions; User can set the password, to prevent others to change the setting parameters;
• Timing Range : 0.1seconds ~ 9999 minutes can be set, cycles 0 ~ 9999 times,
