Miniature signaling relay

General description

• modular plug-in relay
• used as a switching element in railroad signaling equipment
• two plug-in types and one relay type for mounting into relay sets
• easy to change during operation (plug-in units)
• modular construction, small size and weight
• low power consumption and maintenance costs

Basic technical description

• the design of the NMS and NMSM relay types are in accordance with safety level N in compliance with UIC 736
• the relay works in circuits with a voltage of 12 to 24 V
• in case of alternating circuits a diode converter is implemented into the relay
• the work position of the diode is horizontal and the contacts are placed at the top of the board
• a necessity is to install the relays inside a metal box with a relative humidity of max 95%
• the relay controls contacts which form the contact system
• the contact set contains a break contact, break-make contact and a make contact

Compatibility

• AZD Prague signaling systems
