This
device allows to acquire the state of 4 logic input and set the status of
4 Relay output through an RS485 network, using ASCII or Modbus RTU protocols.
It
has a galvanic insulation up to 3750Vrms between the I/Os and the RS485 interface,
and may be used over network segments of 1200mt of extension and up to 32
devices.
The device is provided of extractable terminal blocks as
for the connection of RS485 I/F as for the power supply and I/Os.
The I/Os are optoisolated from the system and equipped with LED for status
signaling.
The wide range power supply (from 18 to 30Vdc) may be connected
through the two extractable TB or through a standard AC adapter (jack 2.1mm).
