/// Socket, push-in terminals, panel mount Sockets for extreme reliability, within long endurance applications and harsh environments Panel / flush mount Very compact solution Sturdy push-in terminals Solid and stranded wires with ferrules can be inserted easily without using a tool Stranded wires without ferrules can be inserted with a flat-bladed screwdriver Twin connection per relay contact Large wires up to 3.3 mm2 (AWG 12) High density matrix of relay/sockets possible, horizontal and vertical stacked Suitable for all railway and industry D8- & KDN relays Easy & quick installation (up to 75% reduction of wiring time) Positive mechanical keying Trifurcated female receiver for tight grip relay pin Clear terminal ID The V88 is a panel/flush mount relay socket. The V88 Connection diagram Bottom view (wiring side) See also page 3 socket has a base with two highly reliable push-in terminals per relay contact, so looping/daisy chaining can be done on the socket and no external connector or terminal is needed. Solid and stranded wires with ferrules can be inserted without using a tool or pressing a lever. Wires up to 3.3 mm2 can be inserted. This quick & easy wiring method saves up to 75% wiring time. Pinning on the socket complies with pinning on the relay. To prevent fault relay placement the socket can be equipped with mechanical keying to accept only designated identical keyed relays. Application The V88 relay socket is suitable for general railway and industry applications with a space saving design. Installation and replacement of relays is made easy and cost saving. No maintenance is required for the user. Suitable for all railway and industry D8- & KDN relays. Railway compliancy Industry compliancy

Mechanical keying relay and socket (optional) Function: • To prevent wrong installation • To prevent damage to equipment • To prevent unsafe situations Using keyed relays and sockets prevents a relay is inserted in a wrong socket. For example it prevents that a 24 VDC relay is put in a 110 VDC circuit. Positive discrimination is possible per different function, coil voltage, timing, monitoring, safety and non-safety. The D relay keying option provides 8 x 8 = 64 possibilities. Upon ordering the customer simply indicates the need for the optional keying. Mors Smitt will assign a code to the...

Installation and 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. No external retaining clip needed as the ‘snap-lock’ will hold the relay into the socket under all circumstances and mounting directions (according shock & vibration requirements IEC...
