We offer an extensive range of analogue trip amplifiers, all suitable for use in SIL 1, SIL 2 or SIL 3 rated (IEC61508) safety system loop monitoring applications and providing voltage free relay output contacts.

Relays are configured for either High or Low Trip action and fail safe as standard. Non fail safe relays (i.e; De-energised in the healthy state) are available on request.

Many additional options are available, including; Digital Displays, high level of RF immunity (to IEC61000-4-3;2006/A2/2010), Latching relays with local or remote reset, fixed or Variable hysteresis, input open circuit response Upscale or Downscale drive, fixed or variable Time delay into trip, isolated analogue repeat and 10V or 24Vdc Excitation outputs.

Mounting arrangement options include; Din Rail, Wall/Surface, Seismic Keyhole plate, Front of Panel and high density 19” or customised Rack enclosures.
