## Overview

The KNACROPTR4-IND is a versatile 4-channel time relay controller designed for precise, programmable automation. It supports independent or sequential relay operation with adjustable timing from 0.1 seconds to 9999 minutes, compatible with a wide DC voltage range (6–40V). Featuring industrial-grade microcontrollers, an easy-to-use LCD interface, and advanced input signal detection, it ensures reliable, secure, and flexible control for complex industrial or DIY applications.

## Description

KNACRO PTR4-IND Controller 4-Channel Time Relay DC 6V 9V 12V 36V 6-40V 0.1s~9999m Adjustable Run independently/in Turn 4ch Load Linkage Run in Turn, Similar to PLC Sequence Control

## Features

- The PTR4-IND controller have four channel time relay, each time relay can run independently, there also can run in turn, four time relay can be controlled by detect four channel voltage signal, such as control four loads independent or alternating on/off, control four solenoid valve independent cycle work or work in turn, control the four input signal delay on-off function and so on.
- 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; Four time relay, timer range: 0.1 seconds ~ 9999 minutes adjustable, close- open cycles is adjustable from 0 to 999 ( “0” means infinite loops ) , timer relays can be set to close first or open first;
- The four input effective signal types can be set to high level and low level, rising and falling edge etc, there can be connected with the switch, the voltage signal, PNP sensor, NPN sensor, the high level signal threshold adjustable (0.1V-40.0V).
- Four effective signal of input can be set to control four time relay trigger to run, high level maintain running, trigger reset and restart etc. User can set the password, to prevent others to change the setting parameters.
