SymCom’s ISS-102C-M-LC (Latching Controller) is an intrinsically-safe
switch for interfacing between hazardous and non-hazardous areas. It
is a dual-input, single output (Form C), pump controller with latching/

differential logic. Both input channels are compatible with switches (oat,
pressure, etc.) and resistive probes (xed 100kΩ threshold). The unit is
congurable for pump-up or pump-down applications.

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.
