Future-proof and cost-effective: IS1+ Remote I/O system

IS1+ reduces TCO in hazardous areas

For greenfield projects and plant retrofits, the market-leading IS1+ Remote I/O system from explosion protection specialist R. STAHL is a future-proof and most cost-effective solution for data transmission in hazardous areas (zone 1 and 2). Compared to conventional point-to-point wiring, the system greatly reduces the wiring effort. Even for a limited number of signals and a control system installed only a short distance away, installations become quicker and cheaper. However, the system offers the most significant savings potential in the engineering and commissioning stages – depending on plant size, typically 40% cost savings compared to conventional installations can be achieved. The integrated predictive maintenance and diagnostics features of IS1+ according to NAMUR NE 107 also ensure maximum process availability and low operating expenses. The fully intrinsically safe structure with an intrinsically safe fieldbus based on PROFIBUS DP or industrial Ethernet Modbus TCP, EtherNet/IP or PROFINET facilitates a simple and easy expansion or modification of the system in hazardous areas: modules can be hot-worked or hot-swapped at any time.

IS1+ includes a range of multifunctional modules, such as an eight-channel module for analog inputs and outputs with HART, a 16-channel module for digital inputs and outputs, or an eight-channel temperature module for 26 different temperature sensors. The signals can be configured individually for each channel. In addition, for almost all intrinsically safe and non-intrinsically safe solenoids, R. STAHL supplies digital output modules which offer eight integrated pilot valves. Thanks to the innovative low-power technology, IS1+ system modules feature a long service life of up to 15 years. They are suitable for use in an expanded temperature range between -40 °C and +75 °C even in extreme ambient conditions. For installations in zone 2, the series also includes cost-optimised input and output modules that are functionally identical.
