RZ3 Series 10-30VDC PNP 0,1-30sec Analog Time Electronic Relay
The RZ3A1A30S2 fits a standard 22mm panel cutout with just 3 wires, and its rotating bezel lets you adjust the delay time from the front of the panel without opening the enclosure — a genuine time-saver for maintenance staff who'd otherwise need to access internal terminals to retune a delay.
Simple, 3 wire flush mounted timer fits a standard 22mm cutout. Rotating bezel for quick adjustment without opening control panels.
When power is applied the timer begins to countdown and outputs a PNP signal after the delay period has elapsed. Max signal current 200mA.
After delay period the output signal is maintained until power is removed from the device.

Frequently Asked Questions
How does the on-delay function work?
Once power is applied, the timer counts down; once the delay elapses, it outputs a PNP signal, which stays active until power is removed from the device.
Can I adjust the delay time without opening the panel?
Yes — the rotating bezel on the front face lets you retune the delay from outside the enclosure.
What's the maximum output current?
200mA, suitable for driving a PLC input or small relay coil directly.
What's the difference between this and the 0.1-60 second version?
Same timer function and PNP output, but this version covers 0.1-30 seconds, while the other covers 0.1-60 seconds — choose based on the longest delay your application needs.
