About This Product

■Product overview

Relay terminal blocks are products that relay signals between control equipment (sequencers) and devices (sensors, etc.) using a connection method tailored to the application.

■Features 1.

It is possible to relay various signals from 20 points inside the control panel to the outside of the control panel using a 20-core cable for outside the panel (prepared by the customer).

■Features 2.

The connector uses DK-3100 series 20 cores manufactured by Daiichi Denshi Kogyo Co., Ltd.

■Feature 3.

It can be used as a relay terminal block from a general-purpose 20P terminal block to a 20P connector.

■Feature 4.

It has a withstand voltage of AC1,500V and can flow a current of 5A at each point.

■Features 5.

The + screws on the terminals are self-up screws, making it easy to install round crimp terminals.

■Feature 6.

Can be mounted using DIN rail or screws.
