Application:
motors
pumps
Functional description:
The INT30x devices can be pro-grammed to operate in two ways.
Mode 1: An output relay is allo-cated to each sensor, the switching point can be individu-ally set for each sensor.
Mode 2: The relays are allocated warning, trip and alarm functions
Special features:
easy 2-key operation
analogue input
analogue output (option: gal vanically isolated)
variable hysteresis
password access possible
All inputs are designed for low voltage - do not con-nect to mains voltage. We rec-
