Reliable Electrical Switching for Industrial Automation
The Finder 62.83.9.012.4070 provides a dependable method of controlling multiple electrical circuits using a separate 12 V DC control signal. When the coil is energised, the relay's electromagnetic mechanism operates three changeover contacts, transferring each circuit from its normally closed connection to its normally open connection. When the coil is de-energised, the contacts return to their original positions unless the mechanical test button has been deliberately locked in the operated position.
A key feature of the 4070 configuration is its combination of a lockable test button, LED indicator and integrated suppression diode. The LED provides a visual indication that the DC coil is energised, while the diode helps limit the voltage spike generated when coil current is interrupted. Because the diode makes the coil connection polarity-sensitive, the positive DC supply must be connected to terminal A/A1. The suppression diode can also increase relay release time compared with an unsuppressed coil, which should be considered in time-critical control applications.
The relay's rear flange mounting arrangement and Faston 250 quick-connect terminals support secure installation and accessible electrical connections. Its three 16 A changeover contacts make it suitable for auxiliary switching, equipment interlocking and machinery control, provided the connected loads remain within the applicable switching ratings. The manual test function must only be used when operation of the connected equipment is safe.

Frequently Asked Questions
What is the Finder 62.83.9.012.4070 used for?
The Finder 62.83.9.012.4070 is a 16 A industrial power relay used to switch electrical circuits in machinery, automation equipment and control panels. Its three changeover contacts allow three independent circuits to be controlled using a single 12 V DC coil.
What coil voltage does the Finder 62.83.9.012.4070 require?
The relay uses a 12 V DC nominal coil with approximately 1.3 W nominal coil consumption. Because the relay includes an integrated suppression diode, the DC supply must be connected with the correct polarity, with the positive supply on terminal A/A1.
What is the contact configuration of the Finder 62.83.9.012.4070?
The relay features three changeover contacts (3PDT / 3 CO). Each contact has a common terminal, a normally closed terminal and a normally open terminal, allowing three independent circuits to change switching state when the coil is energised.
Does the Finder 62.83.9.012.4070 include an LED, diode and test button?
Yes. The 4070 configuration includes a lockable mechanical test button, LED coil indicator and integrated suppression diode. The LED indicates coil energisation, the diode helps suppress inductive switching transients, and the test button enables manual relay operation during safe commissioning and maintenance procedures.
How is the Finder 62.83.9.012.4070 installed?
The Finder 62.83.9.012.4070 is designed for rear flange / panel mounting and uses Faston 250 quick-connect terminals measuring 6.3 × 0.8 mm. The coil connection is polarity-sensitive because of the integrated diode, so the positive 12 V DC supply must be connected to A/A1.
