JCZC3-150 Transmission Relay
  • Product Details

Product Usage

The transmission relay is one of the important equipment in the AC counting code automatic blocking equipment. The DC pulse sent by the electric code transmitter is transformed into an AC pulse by the relay, and then sent to the track circuit.

The JCZC3-150 transmission relay is used for single-line section whole station strand-track coding.


Heavy spring force relay.

The JCZC3-150 transmission relay is connected in parallel with the coil after its capacitance and resistance are connected in series, which can consume the inductive energy when the coil is disconnected.


165mm×49mm×163mm (length×width×height)

Installation method

The relay socket is installed on the combination frame (cabinet) with bolts, and the relay is inserted into the socket horizontally and clamped with a hanging spring.
