Seneca Z170 Signal Splitter and Z109UI Signal Isolator

Ucontrol proprietary Limited are a distributor of automation and process control products some of their most popular product Ranges are the Seneca signal splitter and signal isolator lines. Why are these products popular? let's first look at the Seneca Z170 splitter. Signal splitters are used when there are multiple devices on a single 4 to 20 milliamp loop, but it is important to provide protection between these devices. Or there is not enough voltage to drive the loop through all devices because the input impedance of the input devices is too high collectively. The Z170 signal splitter and signal isolator combination device accepts a single universal process signal input user-selectable buy either dip switches or PC configuration software. This is probably the only signal splitter which accepts such a wide range of inputs.

These inputs include thermocouples, analogue inputs such as 4 to 20 milliamps and 0 to 10 volts, potentiometer, Milli-volts resistance, PT100, PT1000 and NI1000 along with an 18 volt transmitter power supply for 2 wire loop powered devices. There are two isolated analogue outputs which can be configured for Volts or Milliamps. The outputs can be independently scaled using the PC software. So as in the above application separate devices can be connected to each of the 2 different outputs to provide protection. Or we have 2 times the voltage driving capability, if there are many devices on the loop.

The software for this innovative signal splitter is aptly named Easy, it is a wizard based software which is very user friendly and is a free download from the manufacturers website. Z170 performs the function of a signal isolator too, along with other signal isolator products in the Seneca range such as Z109reg and z109UI. the Z109UI is a low priced and versatile product. It can accept a range of analogue inputs which include milliamps, voltage and mill voltage. As with the z170 signal splitter the z109UI signal isolator can also be configured with on board dip switches and PC software.

There is no non linear Inputs this device though such as thermocouples inputs. We do however still have the 18 volt on board transmitter power supply for 2 wire devices. Both the signal splitter and the signal isolator are powered with a wide-ranging 10 to 40 volt AC/DC power supply making them suitable for battery powered applications such as vehicles.
