Current Sensor
TCS Series
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 selfpowered (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.
For more information see:
Appendix B, page 166, Figure 21 for dimensional drawing.
Appendix C, page 169, Figure 19 for connection diagram.
Features:
• Direct connection to a PLC digital input
module
• 3 to 50VDC, 24 to 240VAC
• 1A steady - 10A inrush
• Actuation Points –
2 - 45A (fixed units)
2 - 20A (adjustable units)
• NO or NC solid-state output
• Complete isolation between sensed current
& control circuit

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.
Normally Closed: When the current through the toroid is equal 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 made through the TCS’s toroidal sensor. The trip point range is divided by the number of
turns through the toroidal sensor to create a new range. When using an external CT, select a 2VA, 0-20A output
CT rated for the current to be monitored. Select TCS adjustment range 0. Pass one secondary wire lead through
the TCS’ toroid and connect the secondary leads together.
