SL345 Coming Soon
The SL345 has almost arrived and will replace the SL339-XA. The SL339-XA will remain available with a longer lead time and less functions than the SL345.
The SL339-XA is a variant of the SL339-X0 and operates with bipolar and ac voltage input signals.
SL345 Bipolar Measurements
The bipolar ranges allow input measurements below zero which allows the process output to respond to an extended range of signals. The response time may be set using the 25mS, 400mS (Fast, Slow) switch.
|Bipolar mV ranges||+/- 15, 32,71, 129, 236, 526, 1052, 2104mV|
|Bipolar V ranges||2.8, 6.1, 13.5, 24.5, 49.9, 99.8, 199.6, 399V.|
|Bipolar A ranges||+/- 1, 2, 5A|
SL345 ac Measurements
The ac ranges take multiple readings while detecting the zero crossing of the signal. After a complete cycle the ac value is calculated. This results in accurate amplitude measurement without ripple on signals as slow as 0.1Hz. As a new measurement is available after each input cycle the system response is quicker as the frequency increases. The 'Sample Time' setting sets the fastest output update time, multiple readings are averaged. Slow measurements will at selected sample time or cycle period if longer.
|ac mV ranges||10, 22, 50, 91, 166, 371, 743mVac, 1487mVac.|
|acV ranges||1.95, 4.3, 9.5, 17, 32, 70, 141, 282Vac|
|acA ranges||1, 2, 5Aac.|

SL350 arrives 1/4/19
The SL350 pulse frequency transmitter will replace the FRT150, PRM180, MFT184, FRT287 and the PFC750. All of these products required some form of factory calibration to customer order specification. These hardware modifications and complicated calibration procedures after various internal links are set. Changes in hardware are handled by up to six additional option switches in the order code.
The SL350 has all hardware included for all signals, probes, pulse voltage differences and measurement range from 1 pulse every 5 seconds to 180kHz full scale.
SL350 Pulse Frequency Transmitter
There are two models of the SL350;
- SL350-20 used with supply voltages; 10-60Vdc / 16-42V 50/60Hz
- SL350-10 used with supply voltages; 80-300Vdc / 80-280V 50/60Hz
The SL350-20 will arrive in stock on the 1 of March, the SL350-10 will be toward the end of 2019.
The unit does require configuration with a free windows app and the low cost SL303 USB isolator which can also be used with all other SL series products. Buy more than ten SL series modules at one time and request a free SL303-01 to be added to the shipment. Alternatively we will program the unit for you at no charge.
The SL350 will replace 99% of PRM180 applications. The SL350 will work with a full scale as low as 12 pulses per minute.
The PFC750 has two outputs while the SL350 only has one. A SL350 can be used with a SL339 to provide the additional isolated output. The two units together can be supplied at the same or lower price as one PFC750 and will still use less space on the DIN rail.
Please refer to SL350 - smart line home for more information.
APC258 and PLS257
The PLR255 has been replaced by the PLS257.
The APC253 has been replaced by the APC258.
Both the APC258 and PLS257 feature:
- Two isolated pulse outputs.
- Outputs can Sink or Sourced 3 - 22V Adjustable
- Powered from a wider range power supply.
- Output frequencies up to 10k Hz.
Inputs for the APC258 include AC/DC current & volts, resistance, RTD (Pt100), thermocouple, pH/ORP and pulse.
Inputs for the PLS257 include Low level ac, Low level pulse, DC pulse (200mVpp up to 50Vpp) and proximity sensors.
New more stream lined housing, now includes an external LED for indication of output plus easier mounting.
The RTT508 converts an RTD (Pt100) temperature signal to a dc process signal output and features:
- 2-wire or 3-wire output loop power supplies.
- Standard accuracy 1%, 0.5% optional.
- Standard beige ABS enclosure.
