ELECTRICAL CONNECTIONS
POWER SUPPLY
Terminals 17 and 18 are the power supply inputs of the WS10, accepting any voltage input between 100 and 240 Vac. A few seconds after power-
on the STATUS indicator blinks, indicating the WS10 is running.
The mains power should be one proper for instrumentation or computers.
INPUTS
The built-in WS10 inputs can be used to measure the following types of signals:
•
Analog voltage between 0 to 5 V
•
Analog current between 0 to 20 mA (or 4 to 20 mA with 20 % resolution loss)
•
Digital logic level: Level 0 for signals between 0 and 1V, Level 1 for signals between 4 and 5 V.
•
Dry contact digital signal.
The connections are done on terminals 1 to 8, observing voltage limits and polarities. Sensor cables should run separately from power signals, in
grounded conduits.
The selection between digital and analog inputs, as well as the setting of the ranges for these inputs, are described in the section Configuration of
local inputs. For current type inputs, it is required to change internal jumpers in the WS10.
For the digital inputs, it is possible to associate a function for pulse integration, useful with flow transducers with pulse output. For more information,
refer to Configuration of local inputs and outputs.
HARDWARE CONFIGURATION FOR CURRENT INPUT
For the mA inputs, it is necessary to short circuit internal jumpers in the WS10. There is a separate jumper for each input.
Attention: The following actions require the work of a skilled hardware technician. Use appropriate soldering iron and solder.
1. Open the WS10 back cover.
2. Find the locations of jumpers J1, J2, J3 e J4. The jumpers are identified as follows.
Jumper Input Opened Closed
J2 Input 1
J3 Input 2
J4 Input 3
J1 Input 4
Voltage or switch Current
3. Using solder, close or open the jumper that corresponds to the desired input and function.
4. Re-install the WS10 back cover.
OUTPUTS
The WS10 has 2 relay outputs with SPST contacts: Output 1 (terminals 10 and 12) and Output 2 (terminals 13 and 15). Wiring and loads must
comprise the specification.
Noise suppressors (RC filters) should be installed in parallel to contactors and solenoids coils driven by the WS10 or placed close to it.
SERIAL INTERFACES
The WS10 provides up to 2 serial communication interfaces. The label placed in the WS10 lateral side identifies the installed serial interfaces.
The SERIAL 1 interface is used to communicate with remote equipment using the master Modbus RTU protocol. It is usually an RS485 interface.
The SERIAL 2 interface is intended for communicating with Modems, either internal (provided as an optional) or external. This interface can be
configured to allow access to the WS10 configuration functions. In the standard WS10 configuration, SERIAL 2 is a RS232 interface.
The figure below shows the RJ12 terminal assignments for the SERIAL 1 and SERIAL 2 interfaces.
