V následujícím článku naleznete základní informace o vstupech a výstupech Extensionů Unipi. Detailní informace a technické parametry vstupů a výstupů naleznete v podkategoriích:

Extension

Digital inputs (DI):
Designed to read TRUE / FALSE logic states represented by direct voltage levels (voltage / no voltage). Suitable for reading two-state sensors such as:

switches and buttons
water level sensors
motion sensors
window and other contacts
auxiliary contactors
and other binary sensors and devices

All digital inputs on Unipi Patron, Unipi Neuron, Unipi Axon and Unipi Extension devices feature counter functionality, ie. are equipped with a counter that is able to detect long pulses as well as very short high-frequency pulses.

Relay outputs (RO):
Primarily designed for switching ohmic loads, making ROs suitable for control of lightbulbs, thermoelectric valves, smaller heating elements, small pumps, door locks etc. ROs on Unipi units and extensions are rated for maximum current of 5A at 230 V~ or 30 V⎓.

Analog inputs (AI):
Analog inputs on Unipi Extension modules support the measurement of:

0-10 V⎓ or 0-2.5 V⎓ voltage
0–20 mA current
0–1960 Ω or 0–100 kΩ (eg. PT1000 temperature sensor)

As such, AIs are suitable for reading values from both passive and active analog sensors.

Analog outputs (AO):
AOs are designed for the control of devices with analog control, such as three-way valves, lighting dimmers etc. Analog outputs on Unipi Extension devices support only 0-10 V⎓ direct voltage mode.
