V.E.M. DH48S-S Programmable Repeating Cycle Time Delay Relay

The V.E.M. DH48S-S is a cyclic time delay relay with a digital display. It switches the load on and off repeatedly according to the times you set.

For example, with T2 set to 5 seconds and T1 set to 2 seconds, a connected LED light stays on for 5 seconds, turns off for 2 seconds, and repeats continuously. Unlike a multi-function time delay relay, it needs no external signal – it starts working as soon as it is powered on.

• Function: Programmable repeating cycle (on/off) timer
• On and Off Time Setting Range: 0.1 seconds to 99 hours
• Output Contact Capacity: 5A @ 250VAC
• Maximum Resistive Load: 800W (direct)
• Start: Automatic on power-up, no external trigger signal required

To switch larger loads, use it together with an AC contactor or solid state relay.

APPLICATIONS

Ice machines and any other equipment that needs to be switched on and off periodically.

FAQ

Can the DH48S-S be used as a preset timer or a power-on delay relay?
Yes. With T1 = 00 and T2 = 5s, the load stops after 5 seconds of operation (preset timer). With T1 = 3s and T2 = 00, the load starts after a 3-second delay and keeps running (power-on delay relay).
