ELECTRICAL CONNECTIONS:
POWER SUPPLY:
10...40 Vdc or 20...28 Vac - Connectors 16 and 17, or by T-BUS connector (optional tool) on the base of the module (see the picture placed on the bottom of this page).
ANALOG INPUT:
depending on the type of sensor or signal available, make the connection as shown. For example, to connect a 3-wire RTD sensor requires a connection to terminals 3, 4 and 6. The Thermocouple, whatever it is, it requires the connection between terminals 3 and 4.
To connect a potentiometer use terminals 3, 4 and 6.
To make resistance measurements at 2, 3 and 4 wires to follow the wiring diagram for the RTD.
For ACTIVE current input use the connectors 2 (positive) and 3. For PASSIVE current input use connectors 2 (positive) and 10 . For Voltage input use connectors 1 (positive) and 3.
DIGITAL INPUT:
the QA-OMNI accepts the input pulses from 0,001 Hz to 9,99 KHz, from mechanical contact, NPN 2 and 3 wire, PNP 3-wire with power supply 24 Vdc, namur, photoelectric sensor, Hall, variable reluctance, pulse 24 V, TTL.
For the connection, refer to the diagram as shown.
ANALOG OUTPUT:
for Voltage analog output, connect terminals 31 and 29 (positive).
For ACTIVE current analog output, connect terminals 29 (positive) and 30. For PASSIVE current analog output, connect terminals 30 (positive) and 31. Analog output supply: 13 Vdc, max 30mA.
DIGITAL OUTPUT:
relay Output SPDT. Connect terminal 25 for Normally Open mode, terminal 26 for Normally Close. The default setting is Normally Open (NO).
SERIAL OUTPUT RS485:
available on connectors 32, 33 (B-), 34 (A+), or by T-BUS connector to be mounted on the module
T-BUS CONNECTION (OPTION), needs T-BUS connector:
It may be affixed to the accessory T-BUS based on the module to bring both power and serial communication. The number of modules supported by the bus is a function of the power supply used (check the absorption of the modules).
