Time Relay ZAMEL PCM-04 16A 1NO/NC 230V AC

ZAMEL PCM-04 is an electromechanical time relay for switching single loads up to 16 A. The device provides one changeover contact configurable as normally open (NO) or normally closed (NC) and is powered from a 230 V AC supply. Designed for DIN-rail mounting, the PCM-04 delivers repeatable delay and pulse functions needed in automation, lighting and heating circuits as well as other control panel applications.

Advantages

The relay combines a compact electromechanical design with straightforward installation on standard DIN rails and robust switching capability up to 16 A. Its configurable changeover contact allows flexible use as NO or NC, while the 230 V AC supply ensures compatibility with common mains systems. The relay provides reliable, repeatable timing behaviour for delay and pulse modes without complex configuration.

Suitable for

• Time-controlled switching of lighting circuits in residential and commercial buildings
• Delayed start/stop of pumps and small motors within rated current
• Control sequences in heating systems and thermostatic control panels
• Simple automation tasks in control cabinets and distribution boards

Key specifications

• Type: electromechanical time relay with changeover contact
• Contact configuration: single changeover, selectable as normally open or normally closed
• Switching capacity: up to 16 A resistive load
• Supply voltage: 230 V AC
• Mounting: standard DIN-rail (35 mm)
• Functions: repeatable delay and pulse timing modes

How to use

Install the relay onto a 35 mm DIN rail inside the control panel and make connections according to the circuit requirements: connect the 230 V AC supply to the designated supply terminals and wire the load through the changeover contact. Set the contact mode to NO or NC as required by the circuit and select the desired timing function (delay or pulse) following the product's mechanical or switch settings. After wiring and configuration, restore supply and verify correct timing operation with test cycles before putting the relay into regular service.

Usage recommendations

Ensure the connected load does not exceed the 16 A switching capacity and consider inrush currents of motors or inductive loads; use appropriate protection and contactors for heavy or inductive loads. Mount the relay in a dry, ventilated panel free from excessive vibration and perform periodic inspections to confirm reliable operation.
