The controller is provided with removable terminal blocks for wires having section not bigger than 1.0 mm
2
:
14 ways for supplay, analogue inputs and digital inputs,
12 ways or 6 ways for relays (depending on model)
Note:
•
terminals 17-19 are connected inside the controller (common for the “relay n°1” (terminal 15) and “relay n°2” (terminal 16))
•
terminals 21-22 are connected inside the controller (common for the “relay n°3 ” (terminal 18) and “relay n°4” (terminal 20))
A 5-ways connector is dedicated to the TTL / RS485 interface.
The controller has 4 connectors (depending on model) for remote keyboard, open collector outputs, Pb4 probe, 4..20mA / 0..10Vcc
analogue output; the connectors have 2 ways (0.2 mm
2
wires).
Remote keyboard is provided with 2-ways screw terminal block for wires not bigger than 2.5 mm

.
Check power supply data before connection wires.
Keep the probe and the digital input wires separate from the power cable.
Do not exceed the maximum rating current for each relay, check technical data and if the load is bigger, use filtered contactors.
