Description
Plug-in industrial power relay with 4 change-over contacts. Standard
equipped with a LED indicator and back EMF suppression diode (for DC
voltages). Optionally magnetic arc-blowout, double make/double break
contacts and increased contact gaps for high breaking capacity and long
contact life.
Proven reliable operation in switching high DC voltage / inductive loads and
low currents. No external retaining clip needed as integrated ‘snap-lock’ will
hold relay into socket under all circumstances and mounting directions.
The construction of the relay and choice of materials makes the D-relay
suitable to withstand corrosive atmospheres, low and high temperatures,
shock & vibrating and dry to very humid environments.
Compact design, choice of many options and a wide range of sockets makes
the D-relay an easy and flexible solution to use.

Electrical life expectancy and breaking capacity
The life expectancy values shown below are based on factory tests (test frequency at 1/3 Hz). These
values could be different in real life applications as environmental conditions, switching frequencies
and duty cycles will influence these values. Putting more contacts in series (Y) and increasing contact
gap (X5) will increase breaking capacity and life expectancy significantly.

Instructions
Installation, operation & inspection
Installation
Before installation or working on the relay: disconnect the power supply first (no hot swapping)! Install socket
and connect wiring according to the terminal identification. Plug relay into the socket ensuring there is no gap
between the bottom of relay and the socket. Reverse installation into the socket is not possible due to the
mechanical blocking snap-lock feature. Check to ensure that the coil connection polarity is not reversed.
Relays can be mounted tightly together to save space. When rail mounting is used, always mount the socket in
the direction of the UP arrow, to have proper fixation of the socket on the rail.
Warning!
- Never use silicon in the proximity of the relays.
- Do not use the relay in the presense of flammable gas as the arc generated from switching could cause ignition.
- To remove relays from the socket, employ up and down lever movements. Sideway movement may cause
damage to the coil wires.
Operation
After installation always apply the rated voltage to the coil to check correct operation.
Long term storage may corrode the silver on the relay pins. When plugging the relay into the socket, the
female bifurcated or trifurcated receivers will automatically cut through the corrosion on the pins and guarantee
a reliable connection.
Before actual use of relays, it is advised to switch the load several times with the contacts. The contacts will both
be electrically and mechanically cleaned due to the positive wiping action. Sometimes a contact can build up
increased contact resistance (< 15 mW when new). When using silver contacts one can clean the contact by
switching a contact load a few times using >24 VDC & ~ 2A. Increased contact resistance is not always
problematic, as it depends on circuit conditions.
Condensation in the relay is possible when the coil is energised (warm) and the outside, environmental
temperature is cold. This is a normal phenomenon and will not affect the function of the relay. Materials in
the relay have no hygroscopic properties.
Inspection
Correct operation of the relay can easily be checked as the transparent cover provides good visibility of the moving contacts. If the relay does not seem to operate correctly, check for presence of the appropriate coil voltage
and polarity using a suitable multimeter. If a LED is fitted, it indicates voltage presence to the coil. If coil voltage
is present, but the relay does not operate, a short circuit of the suppression diode is possible (This may be due to
the coil connection having been reversed).
If the relay doesn’t work after inspection, replace the relay unit with a similar model. Do not attempt to open
the relay cover or try to repair. Contacts are calibrated and in balance, touching can affect proper operation.
Also resoldering may affect correct operation. Since 2009 relays have tamper proof seals fitted and once broken,
warranty is void.
Most relay defects are caused by installation faults such as overvoltage, spikes/transients, high/short current far
exceeding the relay specifications. When returning the relays for investigation, please provide all information on
the RMA form. Send defective relays back to the manufacturer for repair or replacement. Normal wear and tear
or external causes are excluded from warranty.
