Single-Function Timer Relays
A single-function timer relay is a simple timer relay that performs only one time function, such as on-delay, and has a single time setting. It is used in panel and machine control circuits where the function is known in advance, such as motor starting, fan and pump delays, and conveyor sequencing. The category mostly includes Tense ERP, ER and ERV series and Entes MCB and GEMO models; there are scales adjustable up to 12 seconds, 60 seconds, 3 minutes, 12 minutes and 60 minutes. Product data lists 48 × 48, 72 × 72 and 96 × 96 mm panel-mount types, classic DIN housings and W-Otomat housings, 8-pin socket or terminal connection, and 220 V AC and 24–240 V AC/DC supply. Select the relay by the scale that covers the time to be set, supply voltage, housing size and connection type, and number of contacts; when replacing a relay, verify that the pin layout is the same. A single-function relay cannot be converted to another time function in the field; in circuits where the function may change, it is not a substitute for a multifunction timer relay.

How to choose Single-Function Timer Relays
A single-function timer relay is a simple timer relay that performs only one time function, such as on-delay, and has a single time setting. It is used in panel and machine control circuits where the function is known in advance, such as motor starting, fan and pump delays, and conveyor sequencing.
- Separate sensing, motion control, logic processing and operator interface requirements.
- Select signal type, supply voltage, communication protocol and I/O count for the machine network.
- Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
