SEIKA front page
SC485B
RS232 / RS485 interface converter for connection of SEIKA sensors with RS485 interface to RS232 port of a computer
[+]
SEIKA front page
print version (pdf)
Features

robust, pressure die cast aluminium housing (IP65) with saltwater proof coating
9...15 Volt supply voltage
either connection polarity
internal 5 Volt stabilizing and internal generation of the +/- RS232 voltage levels
half-duplex RS232 / RS485 bus
up to 128 participants on RS485 bus
9channel SubD RS232 port
LED indicating bus activity
Description

The interface converter consists of an aluminium housing with a PCB, a 9-channel SubD port for the RS232 bus, a 4-channel clamp for the RS485 bus, a plug for the external 12V supply voltage, two LEDs for monitoring system operation, the bus voltage level and termination resistances and the interface electronics with voltage level converters and transmission line drivers and receivers.

Application

The interface converter connects any SEIKA sensor with RS485 data output interface to the RS232 port of a computer.

Technical Specifications

Supply voltage 12Volt ± 3Volt
Current drawn approx.30mA + current drawn by sensors
RS485 terminals 4 x 1.5mm2
RS232 port DSub9 socket
RS485 Bus half duplex
Terminator resistance 100 Ohm, can be disengaged by solder bridge
ESD protection on RS485 bus ±15kV (Human Body Model)
Participants on single bus max. 128
Data transfer rate max. 250kbps
Connection to SEIKA-RS232/485 converter SC485B
NV4a
Filtering signal conditioner for sensor signal matching with symmetrical +/- 4 V voltage output

SEIKA front page
print version (pdf)
Features

low noise and low drift
no regulated supply voltage necessary
internal generation of negative operating voltage
integrated reverse polarity protection
outputs are short circuit proof
highly stable voltage supply for operation of a sensor
protection against reverse sensor polarity
zero position and gain adjustable via potentiometers
electronic components hermetically sealed
optionally frequency programmable, active 5th order low pass filter
optional high pass filter
different connector options
Description

The NV4a amplifies, filters and normalizes the output signals of SEIKA sensors. The symmetrical output signal enables unproblematic subsequent signal processing with standard measuring instruments such as oscilloscopes, transient recorders, A/D converters, multimeters, etc.
Multiple internal switching variants allow for optimal adaptation of signal processing parameters, such as settling time, filter cut-off frequencies and amplification and zero point adjustment, to the measuring task.

Application

The NV4a has its application anywhere a SEIKA sensor is, without much expenditure and under optimal compatibility, to be connected to application specific measuring equipment with optimal matching conditions and subsequent adjustments to amplification and zero voltage are necessary.
