Q: If my meter gives a very short pulse width will the splitter be able to reproduce it?

A: The SY027 has several variants the SY027PSO-BF version can capture short slow pulses and reproduce them as a 20msec pulse.
Q: What are the input connections?

A: Pulse inputs are between B & A where B is the positive and A is the negative, reed switch inputs are between B & C and are not polarity sensitive.
Q: What is causing the output to be permanently on?

A: Check to make sure your input frequency hasn't exceed the specification.
Q: Can I get more than 2 signals from my flow meter?

A: Yes multiple SY027PSO units can have the inputs parralleled. You can get 4 signals from 1 meter with 2 SY027PSOs.
Q: What kind of applications are these used for?

A: It is used for splitting the signal from meters to data loggers and PLCs. It is widely used with water, gas and electricity meters. It is used for isolating, repowering, repeating and conditioning a signal on 2 separate outputs. The Din rail version can be used in road side telemetry Kiosks. It can be used between devices that require voltage switching like PLCs. It is widely used in building management systems.
Q: Does the SY027 require any setting up?

A: No setting up is required, just connect your reed switch, TTL pulse or open collector to the correct input and it will transmit the same pulse via 2 relay outputs.

SY027 Meter Pulse Splitter

The SY027 is designed to convert pulses from meters or other turbine devices and transmit the same pulse via two relay outputs to enable two separate instruments to measure the rate simultaneously. It can be used with electricity,water or gas meters (NOT ATEX). The SY027 PSO has been designed for applications where a pulse is required to be isolated, re-powered and repeated on two separate outputs. It works with inputs from reed switch signals, Opto coupler, open collector, NAMUR or TTL pulse (up to 25V) with automatic debounce, as well as with high frequency pulses. The speed of pulses can be accommodated from very slow to super-fast.  The standard frequency range is up to 1 kHz and a maximum switching voltage of 280V, we also have an extra fast version for a small extra charge we can reproduce pulses up to 5 kHz with a maximum switching voltage of 60V.

The units are widely used in building management systems (BMS) energy management compliance is made easier if this small unit can be retro-fitted to take pulses from an existing meter into a new monitoring and control system. 

The splitter is supplied in a very compact din rail mounted case as standard and requires 7-30V Dc supply. There are options to take it with the DC supply requirements in a small IP65 sealed wall mounting case or with a mains powered option when it is supplied in a larger IP65 sealed wall mounted ABS case with a power input requirement of 85-264V AC. with 4 sealing cable glands.

The SY027 is characterised by a rugged isolated relay contact outputs which offer more flexibility than polarity sensitive transistor or pulse outputs. It is also characterised by a galvanic isolation up to 1500 Vrms and 3000 volt in oil.

If you require a din rail mounting mains powered version please see our SY271-AC

The SY027PSO-F gives a solid state relay pulse output with a bandwidth of 1 KHz.

The SY027PSO-FX gives a solid state relay pulse output with a bandwidth of 5 KHz.

The SY027PSR-P gives 1 x reed relay output and 1 x 0-5V TTL pulse output.

The SY027 PSR accepts a pulse and transmits the same pulse via two relay outputs. The SY027 PSR provides for outputs of up to 55Hz.
