ERS-07 220V Alternating Load Controller Dual Timer Relay
ERS-07 220V Alternating Load Controller Dual Timer Relay
ERS-07 Alternating Load Controller – 220V AC Dual-Channel Timer Relay
The ERS-07 Alternating Load Controller is a compact, DIN-rail-mounted time relay designed to manage two independent loads with perfectly balanced duty cycles. Ideal for industrial automation, DSP delay switch systems, pump alternation, motor switching, and any application requiring equal ON/OFF cycling between two circuits, this relay delivers reliable performance with intuitive LED state indication.
Key Features
- Dual Load Alternation: Automatically switches between two separate loads — Load 1 runs for the set time, powers off, then Load 2 activates for the same duration, ensuring balanced usage and extended equipment life.
- Adjustable Timing: Flexible ON and OFF time adjustment from 1 second to 100 minutes, making it suitable for a wide range of automation applications.
- 3 LED Visual Indicators: Flashing R and L LEDs provide real-time visual monitoring of which load is active and the current switch state — at a glance.
- DIN Rail Mounting: Standard DIN rail mounting for quick, tool-free installation in control panels and distribution boards.
- Built-in Time Relay & Breaker: Integrated safety components ensure secure, stable operation across a broad range of environments.
- Wide Temperature Range: Operates reliably from -20°C to +55°C, suitable for both indoor and light industrial environments.
- Easy Maintenance: Clean ABS housing can be wiped down with a dry swab for long-term, hassle-free reliability.

Frequently Asked Questions
Q: What is the ERS-07 alternating load controller used for?
A: The ERS-07 is a dual-channel time relay that alternates control between two separate electrical loads — such as two pumps, motors, or heating elements — ensuring each operates for an equal amount of time. It is widely used in industrial automation, irrigation systems, HVAC switching, and DSP delay switch systems where balanced load cycling is critical.
Q: Can I adjust the ON and OFF timing independently on the ERS-07?
A: Yes. The ERS-07 allows you to set the ON time (active period) and OFF time (standby period) for each load from as short as 1 second up to 100 minutes. Both loads will operate for the same configured duration, ensuring a perfectly balanced duty cycle.
Q: What type of installation does the ERS-07 support?
A: The ERS-07 features standard DIN rail mounting, making it easy to install directly inside existing control panels or distribution boxes. Terminal connections accommodate cable cross-sections up to 2.5 mm² for straightforward wiring.
Q: Does the ERS-07 work with both 110V and 220V systems?
A: Yes. The ERS-07 is compatible with both 110VAC and 220VAC supply voltages at 50/60 Hz, making it suitable for use in a variety of regional electrical systems.
