Explosion proof I/O module STAHL

With the IS1 R. STAHL present the second generation of Remote I/O Systems with intrinsically safe inputs and outputs.

IS1 is extremely simple to use: A CPU & Power Module and several input/output modules are snapped on to the BusRail (35 mm DIN rail). The unique PowerBus power supply concept, developed especially for use in hazardous areas, makes system planning as simple as for normal industrial I/O systems.

IS1 is particularly flexible: It can be used for small and large signal quantities with the possibility of installing field stations in Zone 1 / Division 1 or Zone 2 / Division 2. Installation in control rooms is also possible. An intrinsically safe fieldbus using copper-wire or fibre-optic technology connects field stations in Zone 1 with the automation devices.

IS1 is extremely economical: Modules with 8 or 16 inputs lower the price per signal. The optional ServiceBus in connection with the "I.S. Wizard" software or a HART-Management System cuts down the time for commissioning, trouble shooting and maintenance.

The new I/O modules for Zone 2 applications can be mixed with the Zone 1 modules on the same BusRail. With this it is possible to design very cost effective field stations. IS1 is now available with Industrial Ethernet / Modbus TCP interface.

Modular Remote I/O System for 35 mm DIN rail mounting:
Installation in Zone 1 / Division 1 or Zone 2 / Division 2, Zone 21 and Zone 22, safe areas
Fieldbus communication: Modbus RTU, Profibus DP V0 and P V1 HART, Industrial Ethernet
Hot swap for all modules
Redundant internal system bus
Full redundancy (many control systems) or line redundancy (all control systems)
Field enclosures in many versions
