Dc6-40v 4-channel Programmable Digital Time Relay Timer Controller

This controller is a 4-channel time relay; each channel of relay can run independently and it also can run in turn. It can be controlled by detecting four channels of input voltage signal to control four loads on/off independently or in turn, such as controlling four solenoid valves to work independently or work in turn, controlling four input signal to delay on/off, etc. 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. Specifications: Timing Range: 0.1s - 9999min Adjustable Cycle: 0 - 9999 times Adjustable Working Power Supply: DC6-40V Four Signal Input Impedance > 100K Input Signal Voltage Range: DC0-40V Working Current: When backlight off current is about 9mA/12V(0.11W) 4 Relays Working Current: about 170mA/12V(2W) Four Set of Conversion(normally open and normally closed) Contact Load: 10A/277V AC or 10A/30V DC Contact Resistance: 100,000 (10A-250V AC) Operating Temperature: -40~85C Item Size: 11 * 8.5 * 3.7cm / 4.33 * 3.35 * 1.45in Item Weight: 196g / 6.92oz Package Size: 15 * 9.5 * 5cm / 5.91 * 3.74 * 1.97in Package Weight: 248g / 8.76oz Package List: 1 * Relay Module
