ISS-105-ISO-4繼電器的安全繼電器規(guī)格書PDF中文資料

Description

The ISS-105 is a “smart” five-channel intrinsically safe relay and

pump controller. The ISS-105 can be configured for pump-up or

pump-down applications or as a five-channel relay covering a

wide variety of applications.

The ISS-105 has a long list of features that are needed for

multiple pump applications and can indicate low, high and

out-of-sequence alarms. If an out-of-sequence alarm occurs,

the skipped pump(s) will be started as intended.

The Model ISS-105 can be set-up to do non-alternating

control, alternating control and alternating control with one

non-alternating pump. The non-alternating pump is intended for

use with an emergency or jockey pump. The ISS-105 can start an

emergency pump once every 50 cycles to keep it working freely.

Using the built-in DIP switches, individual pumps can be disabled

when taken out of service for repair or maintenance.
