Power supply
Terminal Meaning
V≅+
power supply device (not isolated; 24 VAC +10% -15%, 50/60 Hz ±3 Hz, 40 VA max. or
24... 37 VDC, 22 W max.)
V≅-
power supply device (not isolated; 24 VAC +10% -15%, 50/60 Hz ±3 Hz, 40 VA max. or
24... 37 VDC, 22 W max.)
- protect the power supply with a fuse rated 2 A-T 250 V
- if the device is powered in direct current, it is necessary to respect the polarity of the power supply
voltage.
RS-485 port (not available in model PSD4BX3)
Non optoisolated RS-485 port, with MODBUS communication protocol.
Terminal Meaning
GND ground
RS485+ D1 = A = + (terminal 1 of the transceiver)
RS485- D0 = B = - (terminal 0 of the transceiver)
- connect the RS-485 MODBUS port using a twisted pair.
For the settings about the RS-485 MODBUS port look at chapter 7 “CONFIGURATION”.
RS-485 port line termination (not available in model PSD4BX3)
Position microswitch 1 on position on (120 W, 0.25 W) to plug in the RS-485 port line termination (plug in the
termination of the first and of the last element of the network).
High voltage digital input
High voltage digital input (if present).
Part Meaning
DIHV1 high voltage digital input (optoisolated contact; 115 VAC -10%... 230 VAC +10%)
DIHV1 high voltage digital input (optoisolated contact; 115 VAC -10%... 230 VAC +10%)
