| LPS,
Inc. is pleased to offer a complete line of isolation modules
for use in communications, high voltage output drive (sink and source)
and high voltage input reading. These modules provide cost effective
methods for marrying low voltage controls to high voltage loads.
They are designed to operate for long reliable service in demanding
industrial environments. Isolation for the I/O modules is 2500VRMS
for one minute while the RS232DI module is 1520VRMS for one minute.
This makes them ideal for applications with high transient voltages
and different ground potentials. The modules are contained in a
hard epoxy 40 pin DIP package for excellent environmental protection
and can operate from -40°C to +85°C.
Serial communications among electronic systems often require isolation
to insure that ground differences between the systems do not result
in system damage or erroneous data transmission. For problems associated
with RS-232 communications, LPS has developed the RS232DI (pin for
pin compatible with the MAX252 manufactured by MAXIM). The RS232DI
is a complete, eletrically isolated, dual RS-232 Transceiver that
includes isolation for the communications lines and the single +5V
power supply. It can be used for microprocessor (TTL) to PC communications
with no additional parts or configured for PC to PC communications
with the addition of one transceiver chip.
The high voltage output driver modules (SNKQI/SRCQI) deliver a
photo-isolated noise free output from a microprocessor or logic
level system to external loads such as valves, solenoids, relay
coils, etc. The SNKQI and SRCQI are designed to be pin for pin compatible
to allow the user to configure system outputs to either sink or
source current. The high voltage input module (DIGINQI) provides
a photo-isolated, noise free interface from a high voltage load
or sensor to a microprocessor or logic level system. Both output
driver modules and the input reader module have four independently
controlled channels that operate from 9 to 50 VDC and a complete
microprocessor interface. The output driver modules sink or source
up to 250mA per channel and include a reset function that guarantees
all outputs will be disabled during power-up.
