German machine construction and automation engineers often need precise time control of motors, connectors, pumps, fans and auxiliary appliances. A Multifunction Time Relay can coordinate on and off and cyclic operation, while reducing the need for several separate timers.
The SZRM1 offers Delay ON, Delay OFF, Equal ON/OFF ON-start-flasher and Equal ON/OFF OFF-start-flasher functions with an adjustable time range of 0.06 s to 30 h.
1. What were the problems of the German engineers during the period?
Industrial appliances often require motors, connectors, and auxiliary devices to operate in a certain order. Without proper time control, simultaneous switching can increase wiring complexity and complicate management of control systems.
2. How can the SZRM1 control cabinets and control machines?
2.1 Start delay on command panels
The SZRM1 can serve as a multifunction timer relay for control panel applications such as:
For engineers looking for a DIN rail multifunction time relay, the SZRM1 offers a compact solution for the integration of the chronometer function in industrial control cabinets.
2.2 Machine sequence control
Production facilities usually follow a sequence such as:
Main power ON → Start of auxiliary system → Start of engine after delay → Cooling system works.
The Multifunction Time Relay SZRM1 can ensure the necessary delay between these steps and is therefore suitable as a timer relay for machine control.
3. How to use SZRM1 for pumps and fans?
3.1 Pump operating time
Pumps may require delayed start or stop for coordination with valves, motors, or other devices.
With the Delay ON and Delay OFF functions, the SZRM1 can act as an on delay off delay timer relay for these applications.
3.2 Fan control and ventilation
Cooling and ventilation fans should continue to operate frequently after the main machine stops.
The SZRM1 can:
A Multifunction Time Relay can keep the load active for a certain period before the stop.
4. How does the SZRM1 support cyclical industrial processes?
4.1 ON/OFF repeatable function
Some industrial appliances require repeated work at certain intervals of time.
Examples are:
The SZRM1 offers uniform ON/OFF modes with ON-start or OFF-start and is therefore suitable as a multifunction time relay for industrial automation.
4.2 Flexible times
The SZRM1 supports times from approximately 0.06 seconds to 30 hours with short delays and longer operating cycles. The catalogue also describes the 20A/250VAC contacts and adjustment accuracy of ±3%.
5. Why choose the SZRM1 for industrial time control?
The SZRM1 combines delay and cycle time functions in a compact appliance and is therefore suitable for control cabinets, machines, pumps, fans and auxiliary systems.
