*Interface converter ZET 7070 is equipped with an integrated power supply module enabling connection of up to 4 sigital sensors ZET 70xx (in the case if the sensors do not require usage of active primary transducers). In all other cases external power supply module is used – its power range should be more than 1,5 times higher than overall capacity of the devices connected to the primary transducer.

Available product versions

Standard: laboratory version in green plastic casing

Industrial*: standard module placed into leak-proof casing with a transparent cover

*The price is calculated on indiviadual basis

Operating principles

of interface converters ZET 7070

For the protection of measuring networks based on ZETSENSOR RS-485 digital sensors DTB devices are used.

ZETLAB package provides drivers for ZET 7070 modules. ZETLAB data server automatically detects device presence in RS-485 line, reads measurement channel name, measured value, upper and lower range of acceptable parameter values and constantly reads measurement channel data forming constant synchronized channel in ZETLAB environment.

ZETLAB data server scans available addresses of the line. In the case if a new device is found a new channel is dynamically connected to the system.  In the case if a new ZET 7070 device is found, ZETLAB data server also connects new channels.  Thus the line maintenance can be performed in parallel with other channels operation, i.e. the system enables “on the go” elements change.

The sensors can be mounted on the measured object or inside of electrical cabinet together with interface modules providing data transfer.

ZETLAB electrical cabinet has compact dimensions if compared to available analogs. ZETSENSOR modules advantages are as follows: they are easy to install and to dismount, they have power indication and data transfer option, which considerably simplifies on-site system diagnostics.
