Operational specification
For the time dependent functions in circuits of operated railway interlocking system are used the time relays, especially the old types TM 10, TU 60, thermal relay TMŠ 2, MTR2, NTRS etc…
Company BETAMONT s.r.o. produces a replacement for the mentioned relays with their products named “Block of time relays” (hereinafter BČR). In those BČR are used the modern industrial time relays from practical reasons supplemented with electronic circuits for the required applications into railway interlocking systems. These products are designed for a wide range of power supply voltages, their mechanical version allows a quick installation, or exchange.
