Specications

The ISS-102

SymCom’s Model ISS-102 two-channel,

intrinsically-safe switch is designed for multiple

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

controller or two-channel switch. Two 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 a debounce delay feature of 0.5 seconds. Resistance probes

or switches can be used on its inputs. Two LEDs illuminate the output state of either form

A relay. 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.

For more information see:

See Appendix A, page 69, Figure 11 for dimensional drawing.
