TCSG2A工业自动化与控制的监控器-继电器输出规格书PDF中文资料

描述 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.

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.
