Point to Point Gas and Fire Detection Modular Systems
SIL2 Compliant

REL/isp is a plug-in module which fit a standard 3U (51/4") 19 inches eurocard rack.
Each module REL/isp consists of dual input channels designed to operate with (4-20 mA) transmitters, LED’s bar graph or graphic display, built in power supply, audio and
visual alarms.
REL/isp performs redundant five programmable logic outputs with In System Programmable Technology.
ISP Technology allows us to realize programmable and reprogrammable logic functions for each alarm condition.
Reprogrammable capability enables fast and easy modifications of system design, will lead to a substantial reduction of developing, management and systems expansion costs, assuring users continuous updating process, preserving investments for a long time.
All REL/isp units have a standard serial line RS-485 Modbus RTU allowing the connection with a remote master system (PC or PLC).
For REL/isp modules management, our company supplies a software package able to realise real-time supervision, remote control operations, historical trends analysis, as well as alarms management and applications library of ready-to-go configurations.
