THT TYPE INTERFACE UNIT
FEATURES
THT-type interface units share the same DI/DO unit configuration. This gives both models a sleek appearance. Furthermore, the connector and operation display are laid out in the center of the unit, and DI/DO are placed 16 bits each on the left and right. Terminal block sections located on both the left and right sides allow separation of the upper and lower sections, allowing the main unit to be replaced without removing the wiring. TJ-5.5 type test connectors can be mounted on terminal blocks.
Interface unit with built-in DI module
The photocoupler module is built into the external terminal block (screw size M4) and converts 110 VDC to 24 VDC simply by wiring to the terminal block. The internal photocoupler module provides insulation to minimize external surges entering the panel (improved noise performance).
Interface unit with built-in DO module.
A contact relay is built into the outside wire terminal block (screw size M4) to control a 110V DC circuit with a signal (24V DC) from a sequencer. This eliminates the need for relay terminal blocks, which were previously required, and reduces the number of parts mounted in the panel and wiring man-hours significantly. The number of mounted parts and wiring man-hours in the panel can be significantly reduced by eliminating the need for relay terminal blocks that were previously required.
