Programmable Timer Relays Selection Guide: Technical Criteria & Application Standards
Programmable Timer Relays selection guide: technical parameters, mounting and compliance standards, and Schneider Electric, Cata, Entes, ACK comparison.
A programmable timer relay (time switch) is a switching device that automatically turns a load on and off according to a preset program based on the time of day and the day of the week. It is used for loads that need to run at the same times every day, such as signs, shop window and exterior lighting, pool and circulation pumps, electric heaters and irrigation. The category includes Cata mechanical and digital time switches, the ACK time switch with power reserve, the Entes MCB-A analog and MCB-50 digital, and the Tense TTR-10 programmable timer relays; there are models with daily and weekly programming, DIN rail (W-Otomat) housings and a 16 A rated current. Select the model by daily or weekly program needs, the shortest switching step, the power reserve feature that keeps the clock running during a power outage, contact current and load type, and mounting style. A time switch operates by the time of day; it should not be confused with a delay relay, which counts seconds or minutes after a trigger signal. The Programmable Timer Relays category on Welibaba includes 16 active models from leading manufacturers such as Schneider Electric, Cata, Entes, ACK.
Key Technical Parameters for Selecting Programmable Timer Relays
To specify the right Programmable Timer Relays model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Product Type | Mekanik zaman anahtarı, Mekanik zaman saati, Programlama kiti, Programlanabilir dijital zaman anahtarı | Verify against project schedule and load calculation |
| Device Application | BUILDING, Bina | Verify against project schedule and load calculation |
| IP Rating | IP20, IP20 B, Terminaller: IP20 B | Verify against project schedule and load calculation |
| Series | Acti9 | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Timer Relays.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Dishwasher Timer Relays, Off-Delay Timer Relays, Flasher Timer Relays.
