Protection Relays Current Monitoring Relays and Transducers TCS SERIES Current Sensor Description The TCS Series is a low cost method of go/no go current detection. It includes a solid-state output to sink or source current when connected directly to a standard PLC digital input module. Its normally open or normally closed output can also be used to control relays, lamps, valves, and small heaters rated up to 1A steady, 10A inrush. The TCS is self-powered (no external power required to operate the unit) and available with an adjustable actuation range of 2 - 20A or factory fixed actuation points from 2 - 45A. Operation Normally Open: When a current equal to or greater than the actuate current is passed through the toroidal sensor, the output closes. When the current is reduced to 95% of the actuate current or less, the output opens. Wiring Diagram Normally Closed: When the current through the toroid is equal POSITIVE SWITCHING NEGATIVE SWITCHING to or greater than the actuate current, the output opens. When the current is reduced below 95% of the actuate current, the output closes. To increase sensitivity, multiple turns may be L1 made through the TCSs toroidal sensor. The trip point range is divided by the number of turns through the toroidal sensor to L1 create a new range. When using an external CT, select a 2VA, N/L2 0-20A output CT rated for the current to be monitored. Select L1 TCS adjustment range 0. Pass one secondary wire lead through N/L2 the TCS toroid and connect the secondary leads together.
