THT TYPE THTQ TYPE CUnet TRANSMISSION TERMINAL BLOCK
FEATURES
CUnet Communication
By adopting CUnet communication, a master device (such as a PC or PLC) is not required,
allowing installation by simply replacing the terminal block.
*Connection to a master device is also supported.
Noise Immunity
Complies with the noise test requirements of Electric Power Standard B-402 (FY2016 Edition).
Provides excellent reliability in terms of noise immunity, voltage fluctuation tolerance, and insulation performance.
Power Supply Specification
Supports DC100V/110V control input power.
No separate power supply or voltage conversion is required.
Screw Terminal
Based on a standard screw terminal block, the unit incorporates Di devices and electromechanical relays within the terminal block,
and also features a built-in communication module, functioning as an input/output interface unit.
Replacement & Fault Detection
The unit is designed with a replaceable communication module.
It is also equipped with a fault detection function, with status indication via LED and output through dry contacts.
