MR- ST3PF Time relay AC220V Power Off Delay Timer| Time Relay with Base 8Pin 30S 60S 3M 10M Product Description The ST3P series time relay is a high-performance electronic timing c ontrol device, integrating the advantages of small size, light weight, high delay precision, wide delay range, strong anti-interference ability, good reliability and long service life. It is widely applied in various automatic control circuits that require high precision and high reliability, suitable for AC 50Hz/60Hz (rated voltage up to 380V) or DC (12V/24V) control systems, and complies with GB 14048.5, IEC 60947-5-1 and other relevant standards. The series includes two core models: ST3PA and ST3PC, which are designed with different contact configurations to meet diverse timing control needs. 1. ST3PA Time Relay Core Feature: Equipped with dual groups of on-delay conversion contacts (DPDT timed contacts), which can realize two independent delay control functions simultaneously, and the delay time can be flexibly adjusted according to actual needs. Technical Parameters: Delay Range: Multiple gears optional (Code A-G), ranging from 0.05s to 24h, covering most industrial timing scenarios (e.g., Code A: 0.05-0.5s/5s/30s/3min; Code G: 0.5-4min/40min/4h/24h). Supply Voltage: AC 24V/36V/48V/110V/220V/380V; DC 12V/24V, with voltage fluctuation tolerance of 85%-110% of rated voltage. Repeat Error: ≤0.5% + 20ms, ensuring high timing accuracy for long-term stable operation. Contact Capacity: 3A @ 250V AC, 5A @ 28V DC, suitable for most low-voltage control circuits. Installation Type: Plug-in type, compatible with PF083A, PF085A, US-08 sockets; panel installation is available with optional accessories (FTR F01/F02). Application Scenarios: Suitable for automatic control occasions that require two independent delay actions, such as sequential start/stop of motors, delay activation of multiple loads, and interlocking control of production lines, widely used in machinery, electronics, electrical equipment and other industries. 2. ST3PC Time Relay Core Feature: Equipped with one group of instantaneous conversion contacts (SPDT instantaneous) and one group of on-delay conversion contacts (SPDT timed), integrating instantaneous and delay control functions in one device, which can meet the mixed timing needs of different actions in the same control circuit. Technical Parameters: Delay Range: Same as ST3PA, multiple gears optional (Code A-G), adjustable from 0.05s to 24h, with clear scale and easy operation via knob adjustment. Supply Voltage: Consistent with ST3PA, AC 24V/36V/48V/110V/220V/380V; DC 12V/24V, adapting to different power supply environments. Repeat Error: ±0.3% ±0.05s, setting error ≤0.5% ±0.05s, ensuring precise control of both instantaneous and delay actions. Contact Configuration: 1 SPDT instantaneous contact (no delay, action synchronously with power-on) + 1 SPDT delay contact (action after set delay time). Mechanical & Electrical Life: Mechanical life up to 1×10⁶ times, electrical life 1×10⁵ times, ensuring long-term stable operation in harsh industrial environments. Application Scenarios: Ideal for control circuits that require both immediate action and delayed action, such as emergency stop instantaneous signal transmission + equipment delay shutdown, alarm instantaneous trigger + delay reset, and automatic control systems of textile, printing, packaging machinery. Common Features of ST3PA & ST3PC Adopt large-scale integrated circuits, ensuring high precision and stable performance, with strong anti-interference ability against static electricity, radiation and transient pulses. External Dimensions: 50×40×57.5mm, panel cutout size 50.5×40.5mm, compact design, saving installation space. Operation Indication: Equipped with LED indicator, clearly showing power-on and timing status for easy operation and maintenance. Safety Protection: Comply with relevant safety standards, with reliable insulation performance, avoiding electric shock and equipment damage; do not disassemble the case to prevent malfunction.
