THT TYPE INTERFACE UNIT
FEATURES
Both DI and DO modules of the THT type interface unit have the same structure, providing a smart appearance. The connector sockets and operation indicators are located at the center of the unit with 16 bits of DI and DO terminals arranged on the each side of the unit.
Since the terminal blocks on the right and left sides of the unit can be divided from the main unit, the main unit can be replaced without disconnecting wires.
The TJ-5.5 type test tool can be attached to the terminal block.
Interface unit with built-in DI module
The external terminal block (screw size: M4) incorporates the photo-coupler module. Input voltage can be converted from 110 V DC to 24 V DC when it is connected to the terminal block.
External surge voltage applied to the control panel is insulated via the internal photo-coupler module. Thus, the interface unit can minimize surge voltage, resulting in a noise immunity improvement.
Interface unit with built-in DO module
The external terminal block (screw size: M4) incorporates contact relays, enabling a 110 V DC circuit to be controlled with a signal (24 V DC) from a PLC.
With this structure, a conventionally-required intermediate terminal block can be eliminated, enabling a remarkable reduction in the number of parts mounted in the control panel and the number of wiring steps.
