ABB TEIP11 I/P signal converter for standard signals

Concept

The TEIP11 signal converter converts standard electrical signals (e.g. 4 to 20 mA) to 0.2 to 1 bar (3 to 15 psi).

It is therefore the link between electrical/electronic and pneumatic systems.

It is the link between the electrical/electronic and the pneumatic system. The signal conversion process is similar to the patented force balancing method.

The TEIP11 signal converter is characterized by relatively small dimensions and excellent operational stability when subjected to shock and vibration. 

The converter can withstand loads of up to 10 g with less than 1% impact on functionality.

The housing units are available in a variety of versions to suit your installation requirements.

For potentially explosive environments, units are available in intrinsically safe operation or in pressure-resistant packages with international approvals for worldwide use.

Both inputs and outputs are available with different ranges of signal conversion.

The devices require only 1.4 to 10 bar (20 to 145 psi) of compressed air for power.

To ensure smaller dimensions and lower costs, the pneumatic unit does not include an aerodynamic stage.

This reduces air capacity and means that the I/P signaling converter can only be used to control low-flow air systems.

Rail Mounted Control Room Enclosure Units

The rail-mounted control room enclosure is the simplest and least expensive version of the I/P signaling converter.

It is mounted using a mounting base that is compatible with all commercially available EN rails.

The enclosure with plastic cover has a protection rating of IP 20.

Field mountable housings

The field mounting housings are suitable for installation on site or in open areas. The housing can be made of plastic with protection class IP 54;

It can also be made of aluminum with protection class IP 65 or stainless steel with protection class IP 65.

The housings are suitable for wall and pipe mounting.

Special conditions

The I/P signal converters are suitable for an ambient temperature range from -40 °C to a maximum of 85 °C.

If the I/P signal converter is to be used at ambient temperatures above 60 °C or below -20 °C, use cable entries and cables suitable for the maximum ambient temperature plus 10 K or the minimum ambient temperature.

Models with intrinsically safe control heads can no longer be operated as intrinsically safe if the “Ex (enclosure)” protection type and a non-intrinsically safe power supply were previously used.

I/P signaling converter TEIP11-PS Doc. 901068 or TEIP11-PS Doc. when used with flammable gases.

When used with flammable gases, the I/P signaling converter TEIP11-PS 901068 or TEIP11-PS 901069 must be installed outdoors as a pneumatic power supply.

The supplied gas must be kept sufficiently air and oxygen free to prevent the formation of potentially explosive atmospheres.

The gas must always be vented to the outdoors.
