SY027 Meter Pulse Splitter

Our SY027 Pulse Splitter 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 either 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 either a very slow to super-fast.  Isolated relay outputs can be created by the PSR version when an NPN pulse output from a meter needs to be converted to a single relay isolated output or two.

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 Pulse Splitter is supplied in a 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 also with a mains powered option when it is supplied in a larger polycarbonate IP65 sealed wall mounted case with a power input requirement of 85-264V AC. with 4 sealing cable glands.

The SY027 Pulse Splitter 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 also see our SY271-AC

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

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

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

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

SY027Pstretch adjust lengths short fast pulses so that they can be captured by PLCs

SY027PSO-BF lengthens pulses to a fixed 20, 30, 40 or 50 msecs specify on order.

Industrial Applications-

Splitting the signal from meters to data loggers and PLCs.
