ERX-30 multifunction time relay (10 functions) – 12…240 V AC/DC, 1 changeover contact

Product description

The ERX-30 multifunction time relay is a universal control element for delay, switching, pulse control, and periodic processes in automation. It offers up to 10 time functions, covering most tasks in industry and household applications.

It is suitable for:

• automation systems in production (coffee/seed roasting, packaging lines, thermal processes),

• control of ventilation (toilets, bathrooms), heating, air conditioning,

• lighting (staircases, advertisements, displays),

• timing of processes in washing machines and household appliances,

• opening/closing of windows, dampers, ventilation systems,

• control of motors and smaller drives.

The main advantage is the universal power supply 12–240 V AC/DC, allowing the relay to replace many different types in one device.

Mounting is designed for a standard 35mm DIN rail.

Built-in time functions (10 functions)

The relay supports the following modes, applicable at voltages 12 / 24 / 48 / 110 / 230 V AC/DC:

1. Bistable relay

2. Delay on (Delay ON)

3. Delay off (Delay OFF)

4. Flasher starting with a pause (Flasher – start with pause)

5. Delay on after activation + delay off (combination of ON/OFF delay)

6. Flasher starting with a pulse

7. Delay on after activation and delay off after deactivation (ON/OFF DELAY)

8. Pulse generator

9. Single pulse after control input release (Single Shot – falling edge)

10. Single pulse after control input activation (Single Shot – rising edge)

Practical applications

The relay can be used in many applications, for example:

• control of fans in households (toilet, bathroom),

• staircase lighting control,

• turning heating or ventilation on or off at time intervals,

• cyclic control of advertising light panels,

• contact bounce (debounce) for control signals,

• control of processes in the food industry (meat cooking, frying),

• control of pumps, motors, and drives,

• automatic opening/closing of windows, dampers, valves,

• control of devices and production lines.
