Installation and Settings
1. Mounting
Mount the converter to flat surface or DIN35 rail.
2. Connect supply
10-30VAC or 10-60VDC acc. to the picture below. The supply
is indicated by yellow power LED PWR.
3. Connect optical fibers
terminated by SC connector (grinding PC). After
interconnection of TDW-S-4C and RDW-S-4C LED LOCK
switches off.
4. Connect signal wires
according to the pictures below.
Connect RS485 buses to A+ and B- terminals.
For RS422 transmission use e.g. BUS1 for reception and BUS2
for transmission on one side; the other side will then use
BUS1 for transmission and BUS2 for reception.
Terminate the data buses with 120Ωresistance by switching
the DIP switch to ON position.
Connect shielding to only one side to the GND terminal.
5. Connect inputs and relay outputs
IN - digital inputs can be activated by
connection with GND or by low level of TTL.
OUT -relay outputs
max. load 125VAC/0.5A or 60VDC/0.3A
Contacts are closed after input activation.
RELAY LOCK - relay reacting to error conditions. Used for
alarm systems, starting of back-up, etc. The
function is described in the picture below.
6. Indications
LED PWR - by switching on detects supply
LED LOCK - by switching on detects relay closure
- by switching on detects optics interruption
- by switching on detects failure of a remote
device
BUS1,2 Rx/Tx
- green LED Tx blinking – data transmission
- red LED Rx blinking – data reception
RELAY
max. 125VAC/0.5A
or 60VDC/0.3A
