Seneca Z-PC Line module: Z-4AI
The Z-4AI module acquires up to 4 single-ended input signals (voltage or current type) and it
converts them to a digital format (normalized measure).
General characteristics
It is possible to choose if each input is voltage or current type
It is possible to enable/disable each input
It is possible to change: the electrical start/end scale between ± 10 V, ± 20 mA, the
normalized start/end scale between ± 32000
Configuration of the module (node) address and baud-rate by Dip-Switches
It is possible to add/remove the module to/from RS485-bus without disconnecting the
communication or power supply
It is possible to switch automatically RS485 to RS232 or vice versa

resolution=60µV; se 2V<E.E.S.<10V, resolution=300µV
Sampling time
Configurable between: 120 ms or 60 ms
Accuracy

POWER SUPPLY
Supply voltage
10 –40 Vdc or 19 –28 Vac ( 50Hz - 60Hz)
Power
consumption
Min: 0.5W; Max: 2W (to power 4 current loop)
The power supply transformer necessary to supply the module must comply with EN60742
(Isolated transformers and safety transformers requirements). To protect the power supply, it is
recommended to install a fuse.
Input connections
It is possible to connect two types of sensors to the Z-4AI module:
passive sensors, indicated with “S” label (these sensors have to be supplied: by a module
external voltage Vext or by the module internal voltage Vaux);
active sensors, indicated with “voltage generator” or “current generator” label (these
sensors have already been supplied).
In the following figure are shown five possible sensor connections.
