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.
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
Features & Benefits:
- Self powered: No control voltage is required to operate the unit
- Totally solid state and encapsulated: No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity
- Can connect directly to PLC: Solid state output to sink or source current can be connected directly to a standard PLC digital input module
- 1A steady, 10A inrush solid-state output: Provides 100 million operations in typical conditions
- Complete isolation between sensed current and control circuit: Allows you to monitor a load in a separate lectrical system
