Multi-channel 4-20mA Data Acquisition Module,
RS485/232 Output, ASCII Command Set or Modbus RTU
Channel to Channel High Isolation
ISOAD is designed for sensor-to-host data acquisition, suit for collecting
analog signal for detection or controling of remote equipment. Using
the latest passive isolation technology, signal channels are isolated to
each other and the anti-interference capability is greatly enhanced.
The device includes power supply isolation, channels' isolation, A/D
converter and RS-485 module. Each serial port can transfer a maximum
of 255 ISOAD A08 Series modules support two types of communication
protocol, command set and MODBUS RTU. The Command set is
compatible with the ADAM modules. Buad rate can be set by codes, can
work with modules made by other manufacturer.
All the configures and protocol info are stored in EEPROM.
ISOAD A08 Series follow industry-standard design, manufacture, each
channel / output /power supply bear 3000VDC isolation voltage.
Operating temperature range - 45 ~ +80 .
y Reliable Isolated Signals
