SymCom’s ISS-102A-LC (Latching Controller) is a
dual-input, single output (form A), pump
controller with latching/differential logic. Both
input channels are compatible with switches
(float, pressure, etc.) and resistive probes (fixed
100kΩ threshold).
Each input channel is “active” when the
corresponding switch is closed (or low resistance
is detected, if using probes). When the LAG
input (CH2) is activated, the output contact
closes. Following latching/differential logic, the
output contact remains closed until both the
LEAD (CH1) and LAG (CH2) inputs are
deactivated.
The green RUN LED illuminates when the output
relay is energized.
