Description of ๐ KNACRO PTR4-SP Controller 6-40V 4-Channel Programmable Time Relay Delay Switch Module 99 Groups Time - for DC 6V, 9V, 12V, 24V, 36V and Beyond
The PTR4-SP controller can be set 99 groups time (steps), each step the relay switch state can be set switch โON/OFFโ (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 ( โ0โ 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 (figure 2);. The external input high level and low level signals, achieve trigger function, wait input to run, jump to another step ,stop running functions;.
