GTC-700 Series Analog Mux Controller has various built-in functions and equipped with micro-processor and high

resolution A/D converter. GTC-700 is constructed as central studio system and consists of one common unit that

performs collection and display of measurement data and data communication and a 8-channel analog input unit that

measures analog input signal (0 - 20 mA). Analog input unit can be expanded up to 16-channels depending on the

service environment.

GTC-700 Series is built with FND digital display (mA value) and LED that displays status of analog input channel,

operation status of internal network, and power on status for the main power. It has RS-485 port and Ethernet port for

data network.

GTC-700 Series Analog Multiplexer Controller is convenient to build the monitoring system with RS-485 & Ethernet

network. It can construct max. 128 detectors with 1 set of controller. It enables expansion of controller to construct 128

or more detectors. (Max. 32 sets, 4096 channels)

Analog input (0 - 20 mA) port is grounded to protect the system safely in an event of thunderbolt or surge. It is equipped

with high performance microprocessor to scan 128-channels within 1 sec (0.64 sec). Each channel can be span calibrated

for accuracy of measurement and calibrated to compensate the cable route.
