Weidmüller unveiled its new SIL3 Safeseries safety relays — suitable for use in the process industry — at this year’s Instrumentation Scotland and Offshore Systems event, which was held at the Aberdeen Exhibition and Conference Centre on 5–6 September.

According to the company, the 24VDC safety relays fulfil the requirements of EN 61508, SIL3, and are designed for the emergency shutdown of facilities and plants.

A model is available with G3 coating — a requirement for applications where there is a high concentration of hydrogen sulphide.

The monitoring circuit version has a wide voltage input range of 24–30V UC, which enables the detection of high-voltage DC field signals from back-up systems.

Available Atex and hazardous systems

  • Pro-H range — this comprises switch-mode power supplies for the process industry and high-end automation systems; the power supplies have a high mean time between failures, active load sharing for redundant applications and Atex and Zone 2 approval for hazardous-area use
  • Act 20 X range — this PC-configurable, intrinsically safe signal isolator/conditioner range is designed for interfacing to Zone 0 hazardous areas and is suitable for installation in safe or hazardous areas of Zone 2; it is programmed using FDT/DTM software
  • Varitector EX range — this includes pluggable and slim 6mm housed surge protection devices for intrinsically safe signal circuits for use in safe or hazardous areas from Zone 0 to Zone 2; products offer both Atex and SIL approvals
  • Klippin enclosure series — these enclosures have been extended to cover a range of IP ratings and materials; the series now includes TB, STB, K and POK enclosures
  • WMF terminals — these are claimed to enable the efficient and flexible routing and distribution of signals
  • PRV and PPV terminals — these push-in terminals are designed for marshalling signals in control systems; the PRV, with its push-in wire connection, is said to be extremely compact
