Speed Switch & Speed Monitor

1-Speed Switch

SMP Speed Switch is used in connection with pulse sensor to monitor the rotational speed of machine drives. The pulse frequency set by control of the transistor. When the input frequency passes the set frequency internal output transistor is activated. Warning or control equipment can be connected to this output and operate when the speed either increase or decrease from set point. The operation of transistor doesn’t work during start-up time and adjusting mode.

Application

two modes are available for technology of SMP compact speed monitor.

Under speed application

By rotation of motive machine, pulse numbers will be specified, counted and displayed with plated proximity switch. In following, if pulse numbers (rpm) are less than adjusted value by user output (third-wire) will be activated based on type of interior switch model either of NPN or PNP.

Over speed application

By rotation of motive machine, pulse numbers will be specified, Counted and displayed with plated proximity switch. In following, if pulse numbers (rpm) are more than adjusted value by user, output (third-wire) will be activated based on type of interior switch model either of NPN or PNP.

2-Speed Monitor Relay

SMP Speed Monitor Relay SOUD-900A is used in connection with variant pulse sensor to monitor the rotational speed of machine drives 2-wire, 3-wire sensor (NPN and PNP) can be connected to the SOUD-900A.

The pulse frequency is compared with frequency set by control of the relay. When the input frequency passes the set frequency, internal output relay is activated. Warning or control equipment can be connected to this output relay and operate when the speed either increase or decrease from set point. The operation of relay doesn’t work during start-up time and adjusting mode.

Application

SMP speed monitor of type SOUD-900A with three including over speed, under speed and mix provides a system to control and observe the motion of machine such as belt conveyor, etc.

These devices are shaft driven and can indicate the rotary motion of the equipment they attached.

Besides, it shows shaft or motor speed (by rpm); in this way. This digital machine with high precision can either connect or disconnect those two relays in order to control the speed of device just by 1rpm difference and all set information on the system will quickly be recorded that remains unit next settings.

The system has starting delay time witch is adjustable between 0 to 99 seconds that is required to reach the nominal speed.

Voltage supply of this system is 220 VAC and its output is 24VDC.All kinds of sensors such as 2-wires, 3-wires DC, NPN, PNP, NAMUR can be connected to this device. Therefore, it will be suitable to enter any type of pulse but all pulses must be glitch free.

The devices output contains two relays, one of them is considered for under speed and another one for over speed.

There are two LED: green and red.
