Delta TCS Controller
Switch opening circuit controller with current launch coil, model Delta TCS
It guarantees the reliability of the differential protection by monitoring the efficiency of the
release circuit of one or two current launch coil switches and signaling the opening circuit
breakdown through alarm display (front LED) and output relay intervention. It can be used
for all the applications which use the current launch coil circuit to control its efficiency
(for instance safety circuits, acoustic and visual signaling of states of alarm, fire pumps, etc.)

uxiliary supply
direct or alternating current electrical supply which is necessary for
proper working of the device.
Please verify that the available supply voltage meets the one shown on the data label of
the meter
(voltage value and any frequency)
Where a double voltage is shown
(for instance 20...150Vdc / 48Vac)
alternating voltage 48Vac or direct voltage 20...150Vdc indifferently.
In case of direct voltage supply please respect the shown polarities
