6. SIGNAL CONNECTIONS for the 4 CONFIGURATIONS (ALL-in-ONE)
After checking carefully all power supply connections, connect the input signal/s and supply the card.
The output voltage varies from zero Vac to 230 Vac, according to the variation of the control signal.
For the connection of the control signal, use an ordinary twisted-pair cable in disturbance-free environments, while in presence
of environmental electromagnetic disturbances use a shielded twisted cable with the screen connected to earth, keeping it as far
away as possible from other power cables.
The function modes, both always available in the present series, can be:
- MASTER with Set-Point, using the inputs In1–In2–In3 (for 4-20mA, 0-5Vdc or NTC probe)
- SLAVE, using the input In4 ( for 0-10V control signal)
The controllers of the ESY-1/ALL-in-ONE series can be set in the following four (4) configurations, described below.
The OM configuration is standard SELPRO
