Pathfinder Instruments Model TSC-20A
Conductivity Controller with Alarm
OPERATING MANUAL
General Description
The
Model, TSC-20-A
is a microprocessor programmable controller that accepts a conductivity electrode as an input. Outputs are;
one on-off relay;3A mechanical contacts and one Alarm relay, 2A contact. The output can be programmed to operate above or
below the set point; and the alarm is programmed as an absolute value high alarm. The power source is from100 to 240 VAC, 50/
60Hz free voltage there is no need to change connections for different voltages. The controller is programmable from the front
panel via 3 switches, and calibration is done using two front panel adjustments pots. The front panel is a 1/16 DIN, NEMA 4X rated
and mounting hardware is provided.
CRU, RU&CE approvals are standard
