TSBSC

Notes: 1) If necessary, set the stepdown transformer (TR) depending on the voltage on the Shock Relay and electromagnetic contactor (MC). Install an isolating transformer if there is any harmonic noise generating device, such as an inverter. 2) Output relay; Normal condition: not excited, Trip condition: excited 3) Coil capacity of MC connected to the output relay of the Shock Relay is: Throw = less than 200VA Hold = less than 20VA In the event that an auxiliary relay is used, have the output relay of the Shock Relay activate the Auxiliary Relay and have the Auxiliary Relay open/close the MC.

Connection with signal converter

1) Prepare a signal converter to use the monitoring software (PCON) of TSBSC. 2) Use twisted cables and connect as follows.
