Triple loop splitters - new TIM018-Mk2

Improve the security of your distributed 4-20mA loops. The TIM018-Mk2 takes one 4-20mA input and splits it 3 ways. Each output loop can be scaled separately.

Mark 2 triple output 4-20 mA transmitter

This new version of the TIM018 has these improvements over the previous model ...

1. Narrower case, allows denser packing
2. Wide range power supplies cover 95-265 VAC or 11-30VDC
3. Adjustments from the front panel
4. Detachable screw terminal connectors

All loops are load-isolated, so that a problem on one loop won't affect the others.

Look at the diagram below, here you see one transmitter feeding 4 receivers, all connected in series. If the line is broken, all devices loose their signal.

Now look at the system with the TIM018 triple loop splitter included. If any of the receivers on the outputs of the TIM018 are disconnected, the other loops will still function correctly.

SM7 short range radio link

The SM7 is a DIN rail mounting 2 wire radio data modem, mith multiple channels, able to act as a point to point, or point to multiple device.

It has in-built error correction.

It is most often used within factories, linking buildings or vehicles to a remote data source.

MR03 medium range radio link

The MRO3 offers longer range communication than the SM7, so is more suitable for linking sites, such as boreholes to water treatment works.

PD10 USB to RS485 converter

PD10 converters have two interfaces, galvanically isolated.

* USB 1.1 or USB 2.0 port to PC
* RS-485 for communication with your remote device
* baud rate: up to 115,2 kbps

The converter does not affect the data structure of your transmission and is compatible with many industrial communication protocols such as MODBUS RTU.

The PD10 converter is a portable device with power supplied from the USB bus.

External dimension: 65 x 43 x 24mm
