TERMINALS
Terminals are all removable and silk screened to facilitate wiring and
replacement.
Primary power terminal, is made up of three poles, P (Phase), T
Ÿ
(Ground), N (Neutral) and powers the board at 230Vac.
2x0.5 minimum cable section
RS485bus terminal, made up of 4 poles: +, A, B, -
Ÿ
Poles + and – provide 12-18 Vdc secondary emergency power. This
second power source is optional, powering the board in the event of
230Vac power outage (we recommend you use power sources with
buffer batteries).
Poles A and B provide connections to the Clavis converter or Vesta
board. We recommend a 2x0.5 cable or superior, twisted and low
capacity shielded (<100pF/m).
Optionally, we recommend a 2x0.5 cable or superior, low capacity
twisted (<100pF/m).
Maximum distance from Clavis or Vesta 1 Km
For +, - poles cable 2x.05
Digital input terminal, this is a terminal with 10 poles: C, C, 8, 7, 6, 5, 4,
Ÿ
3, 2, 1.
Internal voltage between the digital inputs and C poles (system) is
5Vdc. Therefore, a clean contact without voltage (switch, shunt, relay,
etc.) must be connected between them (INxx and C). If any external
voltage is applied, this will break the board (see wiring diagram
available from Master).
For each input, use a minimum 1x0.22 cable or higher. Maximum
distance 500 m.For each system "C", use a minimum 1x0.22 cable or
higher. Maximum distance 500 m.
Relay terminals, there are 4 (one for each relay) and each terminal is
Ÿ
made up of 3 poles, Cx, NO, NCCx corresponds to the system relay,
NO is normally open and NC corresponds to normally closed.
The following can be applied to these terminals:
- 230Vac utilities, lights, appliance sockets, heaters, etc.;
- low voltage utilities, electrical locks, lights, etc.;
- video signals, RBG.
