Description

The ISS-102 is a two-channel, intrinsically-safe switch designed

for multiple uses including a pump-up/pump-down (latching)

controller or two-channel switch. LEDs indicate the state of the

intrinsically-safe inputs and output relays and user-selectable

options are available including a variable resistance threshold for

float inputs. The ISS-102 enclosure is surface or DIN rail mountable.

-LC Each input channel is active when the corresponding

switch is closed. When the lag input (CH2) is activated, the

output closes. Applying latching logic, the output contact

remains closed until the lead (CH1) and the lag (CH2) inputs are

deactivated. Sensitivity is fixed at 100kOhms with a debounce

time delay of 2 seconds.

-DCS This dual-channel switch has two Form A output relays.

Two LEDs illuminate the output state of their respective Form A

relay. Resistance probes or switches can be used on its inputs.

Sensitivity is fixed at 100kOhms with a debounce time delay of

0.5 seconds.

-MC By selecting the proper functionality through the DIP

switches, you can define a pump-up or pump-down, single or

dual channel non-latching switch. The sensitivity adjustment

(4.7k-100kOhms) allows you to define the input impedance at

which the output relays (one Form A & one Form C) will change

state, with a debounce time delay of 0.5 or 2 seconds.
