Time relay, 1-50 seconds
How it works : At the point of switch power ON , the timer delay starts . Upon expiry of the time , relay turns ON and remain in this position until power is OFF. At the point of switch off, the timer resets, ready for the next operation. Led indication for activated relay. Time delay between 1 and 50 seconds. Fully assembled. PVC box included. Dimensions : - PCB only - 49 x 29 mm. - Box - 55 x 35 x 20 mm. The output, is relay with : - Normally open contact - NO. - Normally closed contact - NC. Relay: 15А/125V DC, 15A/24V DC or AC, 10A/250V AC. Power supply - 10 to 14V

Cycle time relay, 1-120 seconds or minutes
This device is a relay, working as cyclic timer (cyclic time relay). Operating mode is as follow: Work, Pause, Work, Pause etc… You can adjust working and pause time between 1 and 120 seconds or minutes. When power is on (LED Power is on), the relay closed (LED Relay is on) and keep that position, until end of set ON time (Work), then relay is deactivated (LED Relay is off) for the set OFF time (Pause) . When off time end - cycle repeat from beginning and so on. Work time (ON relay) and pause time (OFF relay) are adjusted independently. The two times are independent, ie be regulated separately. The time is from 1 to 120 seconds or minutes. Times is adjusted by two trimmer potentiometer. Potentiometer “WORK“ adjust devise working time - between 1 and 120 seconds or minutes. To switch between seconds and minutes use jumper. Settings must be done when power is off. Potentiometer “PAUSE“ adjust devise pause time - between 1 and 120 seconds or minutes. To switch between seconds and minutes use jumper. Settings must be done when power is off. Dimensions for PCB - 68x30mm. The output, is relay with: - Normally open contact - NO. - Common contact - COM. - Normally closed contact - NC. Power supply - 10 to 14 V DC. Relay: 15А/125V DC, 15A/24V DC or AC, 10A/250V AC.

Time relay, positive pulse activate 1 to 50 sec (with box)
How it works: When the power is on, timer waiting triggering impulse + 12V (green cable). Upon receipt of the impulse, relay turns on and remained in that position until the set time expires. After the time expires the relay is turned off and remains ready (waiting triggering pulse). Led indication for activated relay. Time delay between 1 and 50 seconds. Dimensions: - PCB only - 49x29mm. - Box - 55x35x20mm. The output, is relay with: - Normally open contact - NO. - Common contact - COM. - Normally closed contact - NC. Power supply - 10 to 14 V DC. Current in standby (relay is turned off) - 8mA, current with activated relay (relay turned on) - 48mA. Relay: 15А/125V DC, 15A/24V DC or AC, 10A/250V

Alarm system with code (keyboard 3x4)
Alarm system for home-alert. Based on a PIC16F628 micro controller. 3 zones: - Zone 1 - lag /door/ - Zone 2 - instant /volume sensor/ - TMP Zone - 24-hour security for cable circuits and the system itself. Two 4-digit codes: - user code - ON/OFF position of the system - engineering code - for programming Re-setting of input, output and alarm signal time, re-setting of the user and engineering codes. Input time: 5, 10 and 20 sec. Output time: 10, 20 and 30 sec. Alarm signal time: 30, 60 and 120 sec. Mode /Ringer/ - when zone one is activated /the door opens/ - a sound signal will alarm -Sound and light indication. -Keyboard with 12
